She had been advised by her insurance company to find a [lateral restraint](https://newmans.com/services/building-and-structural-repairs/lateral-restraint "Lateral Restraint") specialist to carry out repairs to the front of the property where lateral movement, cracking and sagging had occurred. [![](https://newmans.com/wp-content/uploads/NBS-2418-460x345.jpg "Property Prior to Repairs and Facade Restoration | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/NBS-2418.jpg)Property Prior to Repairs and Facade RestorationThe client initially contacted two general builders who both advised that they would repair the problem by taking down the affected areas and rebuilding them. Unhappy with this suggestion, that would cause massive disruption, the client sought another solution and contacted us. Following a survey of the property our designers specified the Twistfix Heliforce stainless steel [bed joint reinforcement system](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2 "Bed Joint Reinforcement"), to create a deep masonry beam to distribute the structural loads, in conjunction with Thor Helical lateral restraint ties and delamination ties. Initially the client’s plan was to redecorate the front of the property retaining the white façade. However, having read about our [Facade Maintenance](https://newmans.com/services/facade-maintenance/) services the property owner enquired about our paint removal and brick restoration service. Areas of the render on the “Dutch” section of the façade on the top floor were debonding so this gave us an opportunity to assess the condition of the brick faces underneath. Following free, paint removal and render removal samples, the client took the decision to restore the brick façade to its original state. The render on the upper floor was carefully removed using traditional methods to expose the original brickwork. Any loose mortar was also removed. Thor Helical WHO-60 thixotropic, cementitious grout was then injected into the bed joints and helical bar reinforcement installed where required.

Why has it failed?](https://newmans.com/building-and-structural-repairs/lintels-what-have-i-got-why-has-it-failed/) **Published:** January 3, 2013 **Author:** Jon Newman **Content:** Lintel construction has varied through the decades from very elaborate brick arch lintels to less elaborate concrete lintels. Edwardian & Victorian built properties often feature very elaborate brick arch lintels and having with stood over 200 years of change many of them are showing signs of failure. One of the most common causes of brick arch lintel failure is the change of a load bearing timber window to an uPVC non load bearing window causing the common stepped cracking that apparent on many buildings. [![Lintel Repair](https://newmans.com/wp-content/uploads/DSC03279-460x345.jpg "Failed Lintel | Newman's - Structural Repair Specialists")](https://newmans.com/lintels-what-have-i-got-why-has-it-failed/dsc03279/)Lintel RepairLintel construction has changed with various methods and materials now in use such as flat soldier course lintels, pre stressed concrete lintels and catnic lintels. They can all fail for various reasons such as changes in structural loads, ground movement, and thermal expansion, and in concrete lintels fail due to oxidisation of the reinforcing bar. ![Victorian Built Lintels](https://newmans.com/wp-content/uploads/DSC03694-460x613.jpg "Victorian Built Lintels | Newman's - Structural Repair Specialists")Victorian Built LintelsIn the majority of cases, lintel failure can be repaired using the Twistfix heliforce system, incorporating bed joint reinforcement with pinning ties and resin injection forming masonry beams within the structure alleviating the need for costly disruptive remove and rebuild of the lintel which is the traditional approach. ![Lintel Repair Using Twistfix](https://newmans.com/wp-content/uploads/IMG_3344-460x345.jpg "Lintel Repair Using Twistfix Helical Beams | Newman's - Structural Repair Specialists")Lintel Repair Using Twistfix Helical BeamsNewman’s are experts in lintel repair and have installed lintel repair schemes across London and the South East. **Categories:** Building and Structural Repairs, Lintel Failure **Tags:** bed joint reinforcement, brick arch lintel failure, cracking, Deep masonry beams, lintel failure, lintel repair, period property, refurbishment, resin injection, stabilised, structural integrity, structural repairs, twistfix pinning ties --- ### [What is a cavity Wall? And why are they Used?](https://newmans.com/building-and-structural-repairs/what-is-a-cavity-wall-and-why-are-they-used/) **Published:** January 3, 2013 **Author:** Jon Newman **Content:** Cavity Walls A cavity wall is a fairly modern method of construction used when constructing buildings, it give a gap between the two skins of masonry. The construction of cavity walls began in the late 20th century to prevent the penetration of moisture through the outer skin of the building into the inner leaf of the wall. During early construction of cavity walls the masonry panels were tied using bricks placed end on into the inner skin until a metal wall tie was developed. [![Cavity Wall Construction](https://newmans.com/wp-content/uploads/220px-Cavity_wall.jpg "Cavity Wall Construction | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/220px-Cavity_wall.jpg)Cavity Wall ConstructionThe Introduction of the Iron Fishtail. Cavity construction had begun in the early 1900’s but with a huge house building boom in Britain in the 1930’s cavity wall construction was the main method adopted due to the speed and ease of construction and this new method prevented damp penetration between the two skins. Wrought and cast iron ‘fishtail ties’ were developed and rapidly deployed as a structural component tying the two skins together. [![Corroded Fishtail Wall Tie](https://newmans.com/wp-content/uploads/2013/01/Corroded-Fishtail-Wall-Tie-300x244.jpg "Corroded Fishtail Wall Tie | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/2013/01/Corroded-Fishtail-Wall-Tie.jpg)Corroded Fishtail Wall TieThe Problem. Wrought and Cast Iron are prone to corrosion, this causes them to fail weakening the structure and putting the property at risk of collapse. The fishtail ties corrode and there are many factors that cause the corrosion mainly being oxidisation of the iron causing expansion of the tie which lifts the bed joint it is bedded in causing horizontal cracking and loss of strength allowing lateral movement. Other factors such as aggressive mortar like those found in black ash mortar accelerate corrosion as well as the porous and weak Lime sand mortar often used in London. The problem is rapidly accelerated in coastal areas found across the South East coast due to the high content of salt water present. As well as corrosion tie density and spacing is also a cause of concern as it is often found that there are inadequate wall ties within the masonry panel especially at the weakest points around window and door openings.

The style of Victorian properties varies across the country and the main focus of this article is those properties built in the South East and London. The general era defined by the Victorian period of rule is of 1830’s to early 1900’s and it was an era that changed the face of Britain’s house building. With the industrial revolution introducing innovative techniques and rapid economic growth leading to a boom in domestic, commercial and industrial property building. [![](https://newmans.com/wp-content/uploads/DSC02587.jpg "Typical High Status Victorian Property in West London | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/DSC02587.jpg) The Victorian era of house building led the revival of many previously popular styles of architecture and incorporated these styles that define the Victorian era. Houses were a sign of status and the more wealthy the owner the more elaborate the property, incorporating elegant fascia boards and dog teeth brickwork and high brick built chimneys and large bay windows. The exterior of the property was usually built using solid wall construction using yellow stock bricks laid in a 1 sand and 1 lime mortar mix in a Flemish bond. Flemish bond is a strong bond but the typical mortar mix used is a fairly weak mix with a high permeability to moisture absorption. There is a benefit in using a fairly weak mix with lime in the mix as this allows the structure to withstand a fair amount of structural movement which is why movement joints aren’t found amongst period properties and often aren’t required. The cause for a large proportion of external cracking within the exterior of period properties is caused by common factors such as lintel failure, outward movement causing lateral instability and ground movement causing subsidence and heave. Internally the structure is commonly found to have 9 inch solid brickwork for load bearing masonry partition walls and lathe and plaster separating walls both of which are strong and allow some amount of structural movement. Ceilings are often very high and found with intricate internal plasterwork, decorative mouldings and joinery. The Victorians also installed large timber sash windows that are often load bearing and upon replacement, with non-load bearing uPVC windows, causing lintel failure. The elaborate brick arch lintels often fail upon removal of the timber windows and doors as they are often left unsupported, allowing them to sag causing the brick work and mortar to crack in a common stepped cracking. With stair cases usually running parallel to the external flank and gable walls Newman’s usually find that there are no ties from the external wall into the floor joists or stair case. This allows the flank or gable wall to act freely leaving a lateral instability but with the skill and knowledge our surveyors have we are able to restrain this movement using the innovative Twistfix helical bar creating masonry beams combined with Twistfix lateral restraint ties. [![](https://newmans.com/wp-content/uploads/Masonry-Beams-Ready-for-Grouting.jpg "Bed Joint Reinforcement Repairing Failed Victorian Lintel | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/Masonry-Beams-Ready-for-Grouting.jpg) Victorian foundations differ dramatically from Modern structures that are usually built on large foundations typically on concrete ground beams or reinforced slabs and commercial and industrial buildings being built on piled rafts. The Victorians often didn’t use this method of construction for foundations and instead used to build shallow footings out of a course of 5-6 bricks in a ‘pyramid’ shape spreading the load across the ground and in some cases the footings are no more than 200mm’s deep. Many of these Victorian buildings have stood the test of time and we are often asked “with such shallow foundations, why hasn’t my house fallen down yet?” There is no simple answer to this but the loads from a house typically weighing around 100 tonnes doesn’t actually impose huge forces to the ground as the weight is distributed evenly across the structure and the ground. [![](https://newmans.com/wp-content/uploads/Lintel-Repairs-3.jpg "Outward Movement and Lintel Failure Repaired Using Helical Beams | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/Lintel-Repairs-3.jpg) The problems with the shallow foundations arise due to the shrinkage and heave of the clay soils that are found across London and the South East. Subsidence is a major issue within the South East of England as clay is prone to subsidence which is the shrinkage of the soil and the not so common heave which is the swelling of the soil. This structural defect is usually dealt with by your insurance company of which Newman’s are highly regarded for as a skilled contractor offering piling underpinning and superstructure repairs for a network of insurance companies.

This is often evident at the levels of the masonry where the floor joists run in accordance to the floor and ceiling joists. Tying into the floor and ceiling joists is essential in repairing and restraining the movement and traditional tie bars which are visible on many period properties are no longer required.

One of the first ‘council estates’ built was the Boundary Estate in the East End of London. It was opened in the early 1900’s and is now a Grade Two Listed structure. In 1919 David Lloyd George launched a campaign to build ‘homes for heroes’, this was to be housing suitable for returning soldiers and funding was secured from the government. The Second World War intervened with the house building programme and it wasn’t until after the second war had finished the council house hey-day began. [![](https://newmans.com/wp-content/uploads/DSC02319-460x345.jpg "Typical Lau Housing | Newman's - Structural Repair Specialists")](https://newmans.com/the-history-of-social-housing/dsc02319/)Typical Lau HousingIts estimated that around 4 million British homes were destroyed leaving many people homeless, the government provided large amounts of funding to provide new homes and suburban estates and introduced the New Towns Act 1946 which would shape the social housing we see today. There was a small number of high rise developments introduced in large cities such as Kingston upon Hull, Birmingham and Coventry our focus in this blog is the social housing within London and the south East. Typically across London’s sub-urban housing estates two and three bedroom semi -detached properties were built with a front and rear garden, hot running water and private indoor toilets and bathrooms. Inner city developments didn’t follow suit with many 3-4 storey low level flats being built albeit to similar standards of construction and private bathrooms and toilets. High rise structures were deemed more suitable for areas of inner city slum reform with prefabricated ‘system building’ being implemented for the design and construction of high rise developments. [![](https://newmans.com/wp-content/uploads/DSCF4684-460x345.jpg "Low Level Flats Structurally Restored by Nbs in London | Newman's - Structural Repair Specialists")](https://newmans.com/the-history-of-social-housing/dscf4684/)Low Level Flats Structurally Restored by Nbs in LondonMany High Rise tower blocks have been subject of sub-standard build and problems have arose with these structures such as the ingress of damp, structural defects and huge concern over their ability to with stand unexpected forces such as a gas explosion which is what happened at Ronan Point in East London in 1968. Council housing declined rapidly during the ‘Thatcher era’ with the ‘right to buy’ scheme being introduced, laws were put in place preventing the proceeds of property sales and local taxes being invested into the councils housing stock causing the properties to have a rapid decline in structural integrity. Council estates within London and The south East are still standing and with investment from the decent homes project providing key funding to bring the dwellings to a decent standard of living will ensure the properties suffice. Newman’s have played a key role within the decent homes standard and are proud to have brought many properties on estates up to standard. We have worked with councils and housing associations in order to upkeep and reform their housing stock bringing back to life many void properties for use as homes once again. As well as void properties Newman’s has extensive experience and contracting skills whilst restoring tenanted properties. **Categories:** Social Housing **Tags:** bed joint reinforcement, Deep masonry beams, refurbishment, social housing, structural integrity, structural repairs --- ### [Wall Tie Replacement, Why You Should Always Use a Specialist](https://newmans.com/wall-ties/wall-tie-replacement-why-you-should-always-use-a-specialist/) **Published:** January 30, 2013 **Author:** Jon Newman **Content:** At Newman’s we carry out a large volume of wall tie surveys across London and the South coast to properties that have had a wall tie failure of the original wall ties, but ever increasingly we are receiving more and more inquiries for wall tie surveys after new remedial wall ties have been installed, and failed. There are many different wall ties available on the market to diy’ers and untrained installers who see the installation as simple as drilling a hole, tightening an expander or using a resin or mastic to fix the wall tie. In principal installation is simple, specification of an appropriate tie is also fairly simple, but to do it correctly and install a lasting permanent solution isn’t if you are not experienced. for instance here is a tie installed by a ‘reputable’ cavity wall insulation company who decided they would install wall ties to 9 retirement bungalows….. [![](https://newmans.com/wp-content/uploads/DSC04029-460x345.jpg "Failed Wall Tie | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/DSC04029-460x345.jpg)Failed Wall TieThe wall tie has smashed the brick in half losing all bearing within the brick and it was found to be fixed with a red flexible caulk type mastic.

The need for housing influenced the decision for tower block construction and it boomed. [![the Lawn, Harlow, Essex](https://newmans.com/wp-content/uploads/The-Lawn.jpg "the Lawn | Newman's - Structural Repair Specialists")](https://newmans.com/tower-blocks/the-lawn/)the Lawn EssexTower blocks are constructed usually using three methods; in-situ, Steel frame with infill panel and pre-fabricated panels. In theory all three methods of construction should have provided structures free from structural defect and with stand the test of time. In reality many high rise structures are in urgent need of refurbishment to ensure they do not enter a state of disrepair with the only solution being demolition. With all three methods of construction there are common structural defects found that are often similar across the country. Cracking is usually evident within the external and internal fabric of the structure and the defects are often linked to one or more of these causes of movement, thermal movement, lack of movement joints and failed wall ties or inadequate wall ties. Poor construction methods during the build phase. Concrete failure as well is a common structural defect found which can be caused by many factors such as oxidisation of the reinforcing steel, the reinforcing steel being too close to the surface of the concrete which again causes oxidisation freeze thaw action and chemical reaction to name but a few.

Often they fall into a state of neglect and structural defects occur putting the retaining structure into jeopardy of collapse. There are various techniques used to build a retaining wall and the three common techniques used are called Gravity, Cantilevered and Sheet Piled. There are various other techniques used such as gabion basket, and buttressed walls. With changes in the earth pressure on the retaining wall, changes in the water table and areas of structural defect retaining walls tend to fail. The damage caused by a failed retaining wall is severe and can lead to injuries to persons within the vicinity causing them to be crushed. It can also be damaging to property as often the retaining wall is retaining soil that the property is built on forming an integral part of the structures foundation strength. A slip in the soil can cause your property to subside. And you may be liable for legal action if you have failed to maintain your retaining wall. How to identify a Structural Defects to a Retaining Wall? Cracking and bowing are the main defects that will be evident when a retaining wall fails. This can lead to the wall to collapse completely due to the loss of structural integrity. Retaining walls rely on their ability to act as one structure and with a fracture this will prevent the structure from retaining the soil. ![](https://newmans.com/wp-content/uploads/DSC03337-460x345.jpg "Dsc03337 | Newman's - Structural Repair Specialists")Cracking on WallBefore cracking and bowing of the wall are evident you should check the condition regularly of the wall after the winter months or periods of heavy rainfall. It is important to check that the pointing is still strong and not defective as this will allow the penetration of moisture. It is also important to check the condition of the face of the brick any spalled bricks should be replaced as again this will allow the penetration of moisture which can cause a structural defect. How Can My Retaining Wall Be Repaired? In the early stages of a failed retaining wall it is possible to use helical bar combined with high strength grout as incorporated in the Twistfix System, which Newman’s are approved installers and designers of. With this method it is possible to install lengths of helical bar to create masonry beams which will allow the structure to act as one panel again. In cases of severe outward movement we employ various techniques of restraining the wall by introducing platypus ground anchors that tie the structure to the ground using high tension cables and pattress plates preventing further outward movement. In instances where the loads are extreme piles have been driven in to the ground to resist the outward movement. If your retaining wall is suffering structural defects ensure you contact Newman’s for a free survey and repair specification. ![After Restraint Repairs](https://newmans.com/wp-content/uploads/After-Restraint-Repairs-460x345.jpg "After-restraint-repairs | Newman's - Structural Repair Specialists")After Restraint Repairs **Categories:** Bowing Walls, Building and Structural Repairs, Retaining Walls **Tags:** bed joint reinforcement, bowing masonry, bowing wall, brick repairs, cracked brickwork, cracking, deep bed repointing, Deep masonry beams, lateral restraint, retaining walls, Victorian Building --- ### [Subsidence Repairs](https://newmans.com/subsidence-and-heave/subsidence-repairs/) **Published:** April 3, 2013 **Author:** Jon Newman **Content:** Subsidence is a common structural defect which puts structures in serious jeopardy and at risk of collapse. Subsidence is common across the South East of England and in areas where the ground conditions are formed up of clay. Clay absorbs lots of moisture during wet periods causing it to swell and lift the foundation and once the ground dries it shrinks back to its original state or smaller which causes the foundation to drop.

Lintel Failure is a common structural defect amongst properties of all ages and constructions and Newman’s regularly carry out lintel failure surveys in order to establish the extent of lintel failure and the risk it poses. [![Lintel Failure London](https://newmans.com/wp-content/uploads/DSC01399-460x613.jpg "Lintel Failure, London")](https://newmans.com/wp-content/uploads/DSC01399-460x613.jpg)Lintel Failure LondonLintel failure can lead to the collapse of the masonry it is supporting with catastrophic effect. Lintel failure is often recognised by diagonal stepped cracking which is similar to subsidence but should not be confused as subsidence. [![Lintel Failure, Diagonal Cracking](https://newmans.com/wp-content/uploads/DSC02759-460x345.jpg "Lintel Failure, Diagonal Cracking")](https://newmans.com/wp-content/uploads/DSC02759-460x345.jpg)Lintel Failure, Diagonal Cracking Traditional methods of lintel repair are costly and time consuming with many builders believing the only way to restore the structural integrity is to remove the lintel prop the masonry above and rebuild it. Using modern methods of repair Newman’s can repair lintels by installing Twistfix Helical rods installed in the bed joint above the lintel creating beams above which support the masonry. With fast curing resins lintels can be propped into their original position and fixed saving the aesthetics of the property and time and money. **Categories:** Lintel Failure **Tags:** bed joint reinforcement, brick arch lintel failure, Failed Intel, failed lintels, Intel repairs --- ### [Crack Repairs, London](https://newmans.com/building-and-structural-repairs/crack-repairs-london/) **Published:** April 9, 2013 **Author:** Jon Newman **Content:** Cracking View at This North London Warehouse Newman’s were called upon by a commercial property management company who own various trading estates across London. Many trading estates in London are still Victorian brick built structures that have stood the test of time and are still fully functional. The masonry construction of most of these structures is built using 13 inch solid masonry laid in English bond using lime mortar. This type of construction is a strong bond which will allow slight movement. We were called out to attend site as a matter of urgency due to the crack rapidly widening and in some places was over 10mm’s wide. We carried out a structural survey free of charge the same day and designed a repair specification that would restore the structural integrity without any major disruption to the business operating in the building. [![Crack Repairs, North London](https://newmans.com/wp-content/uploads/Islington-20120802-00113-460x344.jpg "Crack Repairs, North London | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/Islington-20120802-00113-460x344.jpg)Crack Repairs North LondonWe used our own mobile scaffold tower alleviating the need for traditional scaffolding enabling us to be on site just two days after the initial survey. To repair the crack in the brickwork we installed 14 No masonry beams across the crack which was drilled back into the left and right pillars. This method of crack repair not only crack stitches but distributes the loads imposed and distributes them across the masonry preventing further cracking.

Reinforced concrete is used due to its speed of construction and it strength and fire resistance making it an ideal building material. Many of London’s tower blocks and tall buildings are built using a concrete frame with brick in fill panels or cladding and have been standing for over 50 years but due to weathering, poor construction etc many of these buildings are suffering from concrete failure. [![Concrete Repairs](https://newmans.com/wp-content/uploads/2016/08/Masonry-Repairs-Barnes-South-West-London-300x224.jpg "Concrete Repairs | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/2016/08/Masonry-Repairs-Barnes-South-West-London.jpg)Concrete RepairsThere are various reasons that cause concrete to fail such as carbonation, corrosion of the reinforcing, honeycombing, lack of concrete cover, stray electrical current causing corrosion to name but a few. Concrete repairs should only be carried out by suitably trained and experienced tradesmen and at Newman’s we are experienced. We carry out concrete repairs on a regular basis and are able to diagnose concrete failure design a suitable solution and instigate a lasting repair programme.

Combining mortars and specialist coatings we are able to restore structural integrity of failed concrete by removing the defective concrete and treating any steel and applying new mortars. Here is one of our recent concrete repair case studies, a 1960’s built commercial premises suffering from cancer of concrete and cracking caused by thermal movement. **Categories:** Concrete Repair **Tags:** concrete failure, concrete inspection, Concrete Repair --- ### [Wall Tie Replacement, London](https://newmans.com/wall-ties/wall-tie-replacement-london/) **Published:** April 18, 2013 **Author:** Jon Newman **Content:** Newman’s are currently undertaking wall tie replacement, London for one of our council clients. We were called upon to carry out a wall tie survey to 15 properties suffering signs of wall tie failure. The classic signs of horizontal cracking within bed joints highlighted the defects and upon our visual and intrusive wall tie survey we found that the existing ties had corroded causing them to expand and lift the bricks work. [![Wall Tie Replacement](https://newmans.com/wp-content/uploads/2016/08/DSC06810-300x225.jpg "Wall Tie Replacement | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/2016/08/DSC06810.jpg)Wall Tie ReplacementWall tie failure is a common defect among houses built in prior to the 1980’s and buildings of all types and constructions suffer from wall tie failure due to the ties being constructed from mild steel or wrought iron and moisture penetration through the pointing of a building reacts with the metal and causes it to rust and expand lifting the masonry. There are other causes of wall tie failure of which we will cover in future blogs. With this particular project that is underway wall ties are being located using a metal detector and isolated using Twistfix’s unique Clansleeve’s that encompass the failed tie in a sleeve filled with resin that prevents any further corrosion. The sleeve slips onto the tie within the bed joint alleviating the need to remove any bricks.

[![Outward Movement](https://newmans.com/wp-content/uploads/blog1-460x345.jpg "Outward Movement | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/blog1-460x345.jpg)Outward MovementStructures built circa 1970’s often suffer with **Lateral Movement** especially to gable and flank elevations of the property where the floor and ceiling joists run parallel to the brickwork. This is commonly where the **Lateral Movement** will occur due to the large expanse of masonry often having no tie to the joists which will strengthen the masonry. [![Lateral Restraint Tie](https://newmans.com/wp-content/uploads/DSC02384-460x345.jpg "Lateral Restraint Tie | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/DSC02384-460x345.jpg)Lateral Restraint TieHow can we rectify Lateral Movement without Re-building the damaged areas?. Most builders will take one look at a bowed wall suffering from Lateral Movement and assume the only solution is to remove and rebuild the damaged area which is not always the case. In most instances it is possible to tie the defective areas using Specialist Structural Repair methods to provide a far quicker and less disruptive Structural Repair Solution. When Lateral Movement has occurred Newman’s can install **Lateral Restraint Ties** through the external masonry via a 12mm hole into the joists of the affected area. With a resin bond in the brick work we can achieve a high resistance to pull out forces which will restrain further Lateral Movement.

We can use a grouted tie to reconnect bowing external walls to internal walls where Lateral Movement has occurred as well as tying into masonry spine walls we can connect the external wall into stud walls in the same way we tie into floor joists again offering substantial restraint against Lateral Movement. It’s easy to misdiagnose bowing walls as there are other structural defects which could be causing the Lateral Movement such as wall tie failure, delamination of masonry which is particularly common in buildings that have rubble filled walls which we will explain further in our next blog.

Parapet walls came into fashion in the early 18th century when the building act of 1707 was put into place and banned the use of timber projecting eaves in London as they posed a major fire risk so it became common practice to build a brick parapet that projected above the roof giving the building a flat roof look with a slated gable behind the parapet ring. [![Traditional Parapet Walls](https://newmans.com/wp-content/uploads/IMGP1202-460x613.jpg "Traditional Parapet Walls | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/IMGP1202-460x613.jpg)Traditional Parapet WallsMany have a decorative stucco concrete or render finish to them which in a lot of cases are over 100 years old so it’s of no surprise that extreme weathers they withstand and age has taken its toll and lead to their deterioration. What does a parapet wall actually do? It is often used to show a boundary between two neighbouring properties and is often an extension from the party wall of which the roof is supported by. Many still have original cement caps which fail and allow moisture into the property. [![Parapet Wall Repair](https://newmans.com/wp-content/uploads/DSC00749-460x345.jpg "Parapet Wall Repair | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/DSC00749-460x345.jpg)Parapet Wall RepairWeather damage is often the most common cause of failure to parapet walls which affects the pointing or rendered finish due to freeze thaw cycles which then cause fractures and de-bonding to occur which poses a risk to the roof structure and anyone within the vicinity from falling concrete. [![Parapet Wall Repair](https://newmans.com/wp-content/uploads/DSC00784-460x345.jpg "Parapet Wall Repair | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/DSC00784-460x345.jpg)Parapet Wall RepairAs well as falling materials it can also be the root cause of moisture ingress which can lead to timber decay in the roof structure as well as mould and damp infestation so upkeep of a parapet should be of utmost importance. What should I do if I think my parapet wall id defective? You should contact a company like Newman’s or Twistfix and ask for advice or to arrange a survey. It’s important that you use a specialist as many people suffer from wrong advice, specification and installation and then require costly repairs from companies such as us.

Most have required the local builder, plumber or electrician to carry out some form of repairs, but when cracks appear and the words ‘structural damage’ ‘structural failure’ ‘could fall down’ are heard panic sets in. [![Structural Crack](https://newmans.com/wp-content/uploads/IMG_3831-460x345.jpg "Structural Crack | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/IMG_3831-460x345.jpg)Structural CrackThere are lots of Structural Repair companies and DIY kits available but as with all construction works some are good some are bad. We have on many occasions put works right due to failures caused by ineffective structural repairs. DIY kits are available from companies such as Twistfix, of whom we purchase all of our materials from. The kits are simple to use and when installed correctly with the appropriate advice very effective but should you use a DIY kit if you do not have the knowledge to know what you’re really up against? Unless you are totally confident that you know why cracks have appeared and you have the tools and skill to install a repair kit yourself you should contact a structural repair contractor and one that look as though they specialise in the field of Structural Repairs as many don’t. So you make contact with a Structural Repair contractor and take up a free survey. What should you expect from a competent Structural Repair contractor? Well you should expect to meet a surveyor who is time served and has the necessary industry qualifications and is willing to show them. [![Structural Repair Survey](https://newmans.com/wp-content/uploads/DSC04281-460x613.jpg "Structural Repair Survey | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/DSC04281-460x613.jpg)Structural Repair SurveyOnce you have had the survey you should expect a fixed price quotation, confirmation of the cause of cracking and failure. You should also receive a specification of repair and detailed CAD drawings showing the necessary repairs. Newman’s offer a range of technical data produced by the manufacturer Twistfix including their unique method statements and a copy of the BRE testing and load tables with Twistfix being the only manufacturer to have BRE testing carried out to helical repair products.

[![Structural Repairs](https://newmans.com/wp-content/uploads/20140318_164028-460x345.jpg "Structural Repairs | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/20140318_164028-460x345.jpg)Structural RepairsThere are many **Structural Repair** contractors out there that offer a vast range of services so why use Newman’s? The staff at Newman’s have been involved with the field of Structural Repairs for many years and both directors are time served Structural Repair technicians who have passed their knowledge through the company through continued training both on site for our installers and office based training for our designers and surveyors. [![Multi Skilled Staff](https://newmans.com/wp-content/uploads/1-460x345.jpg "Multi Skilled Staff | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/1-460x345.jpg)Multi Skilled StaffWith our recognised industry accreditations and NVQ training our reputation has rapidly grown and we have therefore become an industry recognised specialist who are able to design and install suitable repair strategies to almost any structure suffering from cracking. This particular property had suffered from extensive ground movement due to the clay subsoil shrinking, causing foundation movement which lead to altering load paths necessitating the need for Structural Repairs. Cracking was evident within the render at both ground level and first floor level particularly at window openings which is the weakest part of any brick façade. The cracking was caused by the ground movement but the ground movement also caused the lintels to fail. [![Structural Repairs](https://newmans.com/wp-content/uploads/20140319_160247-460x345.jpg "Structural Repairs | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/20140319_160247-460x345.jpg)Structural Repairs**Structural Repair** product supplier, **Twistfix**, supply a range of bed joint reinforcement products which enable us to repair the structural integrity of the masonry without the requirement for sub structure works such as underpinning or piling as the movement was monitored for a period of 12 months and the results proved the movement was no longer continuous. The Structural Repair scheme involved hacking off render slots to enable us to ensure the bed joint reinforcement was installed into the brickwork and not just into the render. You will notice many Structural Repair companies will cut into the render and reinforcement the render but not the brickwork!

This method of Structural Repair ensures that if further ground movement occurs the masonry will resist the movement providing a long lasting structural solution which was guaranteed for a period of 10 years by one of the only genuine insurance backed guarantees on the market.

Stay Calm, We Can Fix It!](https://newmans.com/building-and-structural-repairs/crack-in-wall-stay-calm-we-can-fix-it/) **Published:** November 10, 2014 **Author:** Jon Newman **Content:** The chance of the crack in your wall being caused by subsidence and requiring underpinning and/or rebuild is very slim. Cracks in walls are the result of some kind of movement causes stress that the bricks cannot sustain. Movement can be caused by a variation in moisture, either in the wall itself or in the ground that supports it, temperature variations, chemical reactions or by replacing load bearing, wooden windows with non-load bearing UPVC windows. Some movement comes and goes with the seasons and other movement is permanent. Walls tend to crack where the bricks are over-stressed and have the least amount of restraint such as in corners and around window and door openings.

Cracks in walls that are active or are more than 5mm wide should be carried out be a specialist, structural engineer. Active cracks of more than 15mm require investigation by a structural surveyor.

Whilst they were pricing the works we were asked to carry out a [**Structural Survey**](https://newmans.com/services/Property-Surveys/Structure-Only-Report) to identify any causes for concern. Whilst carrying out a [**Structural Survey**](https://newmans.com/services/Property-Surveys/Structure-Only-Report) we discovered extensive lintel failure, almost every lintel had failed offering very little support to the masonry above. Diagonal stepped cracking indicates Lintel Failure within brickwork and fortunately for the contractor’s client we have Twistfix’s 2nd generation Helibeam system available to us. [![Lintel Failure](https://newmans.com/wp-content/uploads/blog-21-460x613.jpg "Lintel Failure | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/blog-21-460x613.jpg)Lintel FailureTraditional methods of repairing the masonry would involve removing the lintel and rebuilding which can be costly, time consuming and disruptive as well as quite dangerous. Using the Helibeam system we can create load bearing beams by removing the mortar joint and installing two helical wires encompassed in a thixotropic grout which creates the Helibeam. By installing two cords of helical wire in the bed joint with another pair installed above we create the tension and compression beams which support and reinforce the masonry above. [![Helibeam System](https://newmans.com/wp-content/uploads/2013/11/blog-3-460x613-300x169.png "Helibeam System | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/2013/11/blog-3-460x613.png)helibeam SystemThe Helibeams are being installed above every lintel across the length of the building requiring over 400m’s of helical wire.

The bridge has a 5 arch span constructed from Cornish stone and granite with brick arch spans leading from the bank side to ground level which are built from London yellow stock bricks and the arches in filled for storage and access paths. [![Cracked Brick Arches and Rotated Piers](https://newmans.com/wp-content/uploads/DSC08045-460x345.jpg "Cracked Brick Arches and Rotated Piers | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/DSC08045-460x345.jpg)Cracked Brick Arches and Rotated PiersThe brick arches have come under stress from vibration and increased loads and being over 120 years old have begun to fail leading to cracking and delamination of the ring arch brickwork. Cracking through the soffits are apparent as well as cracking to the spandrel walls. The bridge is going to be undergoing a planned 6 month closure for re-surfacing works and essential reinforcement works. The masonry will be reinforced using Twistfix’s unique masonry reinforcement system which will include over 3000 metres of bed joint reinforcement to increase the arches capacity and stitch the brickwork. As well as reinforcement to the soffit of the masonry arch cracking and rotation to the brick piers will also require stabilisation with the installation of bed joint reinforcement and pinning ties combined with high bond resin injection to provide a lasting repair.

Once the reinforcement works are completed we will subject the reinforcement to digital load tests to confirm the reinforcement programme has worked and in most cases we excel the required load expectations with the installation of bed joint reinforcement.

The Doff is a self contained system that superheats water to up to 150°C to produce steam. The pressure of this steam can be controlled by the operator to enable the cleaning of a wide range of building materials. Because the Doff system does not use any acids or abrasives and the pressure is fully adjustable, it can be used for cleaning all manner of building materials and substrates. Removing carbon from bricks, removing vegetation from stone, cleaning roof tiles, removing graffiti from walls, removing paint from stone, cleaning stucco, cleaning intricate detailing in brick, stone, terracotta etc Because the temperature of the steam is so high it kills of spores in organic matter such as moss and lichen which impedes their regrowth and significantly increases the time between cleaning. The Stonehealth Doff cleaning system is the number one choice of conservationists and listed building officers.

The extension had been built on inadequate foundations causing it to subside leaving the addition with cracking in various areas. We were asked to design a scheme that would restore the structural integrity of the masonry where cracking had occurred and prevent any further subsidence. As the homeowner had already used a large amount of their savings and a failed claim to the insurers, we monitored the movement and designed a bed joint reinforcement scheme that would restore the structural integrity alleviating the need for piling or underpinning. Deep masonry beams were installed to the external skin of masonry wrapping around the structure along with deep masonry beams to the internal skin tying to the external structure. Crack Stitches were also used to tie separated masonry to the internal skin. The repairs were made good with local areas of plastering and repointing. The movement was monitored for 12 months and there was found to be no further movement and the repairs were guaranteed against failure for ten years.

Subsidence is a common problem in London and the South East of England with an estimated 3.7 million home owners at risk within the region covering over 140,000 postcodes. Why is subsidence such a problem in London and the South East? Well the majority of the properties within London and the South East are Edwardian or Victorian built and certainly the vast majority were built before the 1970’s. Built on shallow foundations on a clay sub soil which is susceptible to shrinkage and heave with our ever changing adverse weather condition causing changes in ground conditions causing subsidence. How is subsidence recognised? The location of the cracking for subsidence is normally located around window and door openings in vertical staggered form with the width of the crack normally wider at the top than at the bottom, Heave is different, it is the expansion of the sub soil lifting the building and this is recognised with similar crack locations but often the crack is wider at the bottom than at the top. Subsidence is caused by ground movement but in order to locate the source of the ground movement obvious factors are undertaken during our survey such as the location of tress which can suck large volumes of moisture from the soil, drains – which in some instances fail causing the soil beneath to wash away. Excavations beneath the ground such as tunnelling for Londons crossrail, expansion of the water and sewage systems and the increasing number of basements can also be the culprit of subsidence. Subsidence and heave can in some instances be repaired using the Twistfix Heliforce system by creating masonry beams across the brick panels connecting the whole building allowing it to act as one structure instead of individual brick panels that distributes structural loads. In instances were subsidence cannot be repaired using the Twistfix Heliforce system alone, it is incorporated with either mass concrete underpinning or more conventionally mini piling systems that drive piles down to bedrock or firm made up ground preventing the structure from subsiding or heaving in the event of further ground movement.

They are everywhere and a large number of them are well over 100 years old. Victorian built retaining walls are usually constructed using 13 inch solid brick work construction with a soft lime mortar and usually they haven’t been inspected for signs of failure or disrepair until they are at a critical stage of failure. At Newman Building Solutions we are regularly required to design a suitable structural stabilisation programme that will restrain further outward movement or collapse as well as retain the original charm of the structure. Newman Building Solutions specialise in retaining wall restraint and use various modern methods of structural repair such as the Twistfix helical system creating masonry beams and crack stitches tying the masonry together. In some instances ground anchors are required to restrain the outward movement. Twistfix helical systems can be guaranteed for up to 25 years and ground anchor solutions can be guaranteed for up to 99 years. We like to restore these engineering marvels and relish the opportunity to conserve the original structure.

Bowing walls are caused by a lack of lateral restraint, which allows the masonry panels to move independently often outwards severely weakening the structural integrity of the property. This is often evident at the levels of the masonry where the floor joists run in accordance to the floor and ceiling joists. Tying into the floor and ceiling joists is essential in repairing and restraining the movement and traditional tie bars which are visible on many period properties are no longer required. Newman Building Solutions utilise the Twistfix Heliforce system providing lateral restraint by inserting 1.0m, 1.5m or 2.0m ties into the floor and ceiling joists with a resin fix into the brick work providing an almost invisible repair once aesthetic brick repairs have been carried out. Incorporation lateral restraint ties with helical bar creating deep masonry beams and replacement wall ties remove the need for expensive intrusive and dangerous remove and rebuild techniques that may have been previously used. Here is a selection of projects that this method of repair has been used to restraint outward movement. **Categories:** Bowing Walls **Tags:** bed joint reinforcement, bowing masonry, bowing wall, cracking, Deep masonry beams, lateral restraint, outward movement --- ### [Failed Intel survey in balham south west London SW12](https://newmans.com/building-and-structural-repairs/failed-intel-survey-in-balham-south-west-london-sw12/) **Published:** January 25, 2013 **Author:** Jon Newman **Content:** Structural survey to this Victorian terrace property, recommendations include Brick Arch lintel repairs using Twistfix helibar and thixotripoc cementitious grout covered by a 10 year insurance back guarantee.

[![Diagonal Cracking Above Opening](https://newmans.com/wp-content/uploads/20130505-160050.jpg "Diagonal Cracking Above Opening | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/20130505-160050.jpg)Diagonal Cracking Above OpeningDiagonal stepped cracking often indicates that the lintel that supports the masonry above the opening has failed. There are many types of lintels available and in use such as brick arch and soldier course lintels commonly found in period properties. Newer lintels are normally steel Catnic type lintels which can also fail showing signs of diagonal cracking above the opening.

[![Diagonal Cracking Above Opening](https://newmans.com/wp-content/uploads/20130505-160107.jpg "Diagonal Cracking Above Opening | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/20130505-160107.jpg)Diagonal Cracking Above OpeningLintel Failure often occurs upon the removal of hardwood windows that were originally designed to bear a substantial load without distorting and are replaced with standard uPVC windows which are non-load bearing allowing the lintel to drop or bow causing sagging of the lintel which is shown by the diagonal stepped cracking. Traditional methods are to remove the lintel and rebuild it, this is an intrusive method of repair and a slow process typically taking around a day to properly remove and replace a lintel. Lintels can now be repaired using the Twistfix Helical System by using their [Bed Joint Reinforcement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2) which effectively creates a new lintel within the existing masonry by remove the mortar within two bed joints above the lintel and inserting helical rods encompassed in grout to create a load bearing lintel which spreads the structural loads across the length of the bars preventing further sagging of the lintel.

This defect is especially common in Edwardian and Victorian properties but is also evident in properties of all ages. [![Bowing Wall](https://newmans.com/wp-content/uploads/20130507-085608.jpg "Bowing Wall | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/20130507-085608.jpg)Bowing WallBowing walls should not be regarded as ‘just the way it was built’ this is a serious structural defect that will require a structural repair solution in order to prevent further movement or complete failure. If the bowing in the wall is only at the levels where the floor joists run either into or alongside then this is more than likely to indicate that lateral movement also known as outward movement has occurred. [![Lateral Restraint Tie](https://newmans.com/wp-content/uploads/20130507-085624.jpg "Lateral Restraint Tie | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/20130507-085624.jpg)Lateral Restraint TieLateral movement occurs when there is no connection between the masonry and the floor joists or stair case allowing the masonry to move independently. In order to prevent further outward movement you must provide a connection between the two. Newman’s utilise Twistfix lateral restraint ties which are an 8mm stainless steel tie which are installed externally through a 12mm hole in the masonry into the floor joist. With a concealed resin fix to the masonry we are able to tie the masonry to the floor joist which restrains any further movement.

[![Expansion Joints](https://newmans.com/wp-content/uploads/20130508-140856-460x345.jpg "Expansion Joints | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/20130508-140856-460x345.jpg)Expansion JointsThermal movement doesn’t pose serious threat to the structural integrity in the first instance but over time the damage caused can become very serious. Bricks and mortar are extremely strong and able to resist high compressive forces but offers very poor performance when subject to tensile forces. Thermal movement is basically caused by the expansion and contraction of the fabric of the building due to hot and cold weather. When it’s hot the masonry expands causing compressive forces which the masonry can cope with due to its high compression strength but once it’s cold the material shrinks with tensile forces causing cracking. This cycle is repeated and small cracks eventually turn into large cracks. Period properties rarely suffer from Thermal movement as many were constructed using soft lime mortars which allow movement slight movement usually accompanying thermal movement. [![](https://newmans.com/wp-content/uploads/20130508-140848-460x345.jpg "20130508-140848.jpg | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/20130508-140848-460x345.jpg)Cracking Due to Thermal MovementModern structures are sometimes built without any expansion joints so the thermal movement cannot be accompanied within the masonry so cracking occurs. Remedial measures are required in order to prevent further cracking and this should only be carried out by a specialist. Expansion joints are usually a 20mm wide cut which creates a separation in the masonry allowing each panel to accommodate the movement without cracking occurring. [![Expansion Joints](https://newmans.com/wp-content/uploads/20130508-140838-460x345.jpg "Expansion Joints | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/20130508-140838-460x345.jpg)Expansion JointsNewman’s use the unique Twistfix system which incorporates specialist slip ties and the patented CD drivefix tie combined with a backing cord and flexible mastic creating an expansion joint.

Re-pointing is a delicate process that should only be carried out by a specialist as when carried out incorrectly it can be extremely costly to put right and look awful. Newman’s only use directly employed time served Re-pointing technicians to carry out Re-pointing works. Newman’s have been awarded a lucrative contract by Travelodge who are rapidly expanding their hotel chain and have recently bought a number of properties in London with structural issues and Re-pointing works.

The property below was suffering from areas of Re-pointing failure caused by freeze thaw cycle which had blown areas of the pointing particularly to the parapet wall which required grout injection and vertical ties to reinforce the parapet. Areas beyond repair were rebuilt along with the installation of new coping stones. Newman’s carried out the works in under 2 weeks causing minimal disruption to the duration of the contract working alongside allied trades.

[![Lintel Failure](https://newmans.com/wp-content/uploads/DSC01400-460x613.jpg "Lintel Failure | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/DSC01400-460x613.jpg)Lintel Failure[**Lintel Failure**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) leaves a crack pattern that is instantly recognisable by its distinct stepped Diagonal Crack which usually starts from one corner of the opening to the other. *Lintels* are a vital structural component within the masonry as they support the weight above an opening and prevent the masonry from collapse. Failed Lintels impose serious structural defects and should not be ignored or cracks simply just resin injected and repointed which is the preferred choice of repair for many builders and DIY enthusiasts. Traditional methods often involve the removal of the existing *Failed Lintel* and the installation of a new lintel often a concrete or catnic type lintel. This method of repair is not incorrect and will restore the structural integrity of the masonry but it can be costly, time consuming and disruptive.

We are all guilty of ignoring the external fabric of our property and most of us do not realise how important it is to maintain not only our gardens but our structure too. Newman’s surveyors often carry out [**Structural Surveys**](https://newmans.com/services/Property-Surveys/Structure-Only-Report) to assess cracks which could possibly have been avoided by carrying out just a few hours maintenance in the summer but unfortunately weren’t carried out causing structural defects. Maintenance needn’t be expensive and here are a few steps to prevent cracks and damp occurring in your property. **Starting with the roof**; Have a look for any damaged or broken tiles and have them replaced or repaired if damaged or missing tiles are spotted. Water ingress into your roof structure can become extremely serious with rot occurring in the rafters and timbers supporting your roof. Flat roofs should also be inspected for any tears in the covering. Check for any damp spots internally in your flat roof. Companies such as Twistfix supply many very high quality repair products which are yet cost effective. [![Broken Roof Slate](https://newmans.com/wp-content/uploads/broken-roof-slate.jpg "Broken Roof Slate | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/broken-roof-slate.jpg)Broken Roof Slate**Flashings**; Visually check the lead flashings for wear and deterioration these weak spots often allow water into the structure through capillary action although only small amounts of moisture penetrate once the cold weather comes the freeze thaw cycle begins which can cause cracking and moisture entering the structure will cause damp. If a flashing needs replacing again companies such as Twistfix can supply easy to install **Lead Free Flashings** which most competent DIY’ers can install themselves. [![Lead Flashing](https://newmans.com/wp-content/uploads/lead-flashing.jpg "Lead Flashing | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/lead-flashing.jpg)Lead Flashing**Gutters;** check your gutters and down pipes aren’t leaking or blocked, often leaves and moss fall into or grow within them and can prevent rainwater from flowing freely into the drainage system. If rainwater is leaking or over flowing from blocked gutters during wet spells this can cause soil erosion, literally washing away the soil your buildings foundations are built on leading to major cracking, foundation movement and subsidence or heave. If your insurer discovers that the cause of subsidence is due to negligence you will not be insured. If blocking is a common occurrence then you should consider installing a [Gutter Guard](http://www.twistfix.co.uk/gutter-guard) which prevents blocking and again this is something Twistfix supply. [![Blocked Gutter](https://newmans.com/wp-content/uploads/gutter.jpg "Blocked Gutter | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/gutter.jpg)Blocked Gutter**Masonry**; You should visually inspect your walls for signs of cracking, often hairline cracks are an indication of movement occurring and whilst they are just minor cracks repairs are far simpler to carry out and often cheaper and less disruptive. Missing mortar or failed pointing should be replaced as this is a barrier between the brickwork and will prevent moisture penetration.

Trees and large shrubbery to close to a property can cause major structural issues. Roots often penetrate through concrete and brick foundations causing them to fail during their search for water. As well as root penetration trees and shrubs absorb large amounts of water and in the South East most of our properties are built on clay which hold large amounts of water but in dry spells the clay will shrink and can cause foundation settlement so it is important to control the growth of trees and vegetation.

My wall is leaking… this is a phrase we have been hearing since December from panicking homeowners faced with wet walls from penetrating damp. With Britain facing yet more storms and frequent downpours are you worryingly become noted of the lack of general maintenance to the outside of your property? With Penetrating Damp causing puddles of water inside your house. [![Wet Walls](https://newmans.com/wp-content/uploads/wet-wall-1-460x613.jpg "Wet Walls | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/wet-wall-1-460x613.jpg)Wet WallsWe have been exceptionally busy with calls and emails asking for advice and solutions to prevent Penetrating Damp to period properties. Period properties are suffering badly with this wet weather being faced with driving rain driven by gale force winds the porous brickwork is acting like a sponge absorbing the moisture and with no cavity the moisture has nowhere to go other than through the bricks and mortar into the plaster until eventually the plaster can hold no more water. This phenomenon is become ever increasingly more severe and shouldn’t be ignored, Penetrating Damp can pose severe risks to a person’s health as well as structural issues and if left untreated can be a costly affair. [![Penetrating Damp](https://newmans.com/wp-content/uploads/ww2-460x613.jpg "Penetrating Damp | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/ww2-460x613.jpg)Penetrating DampNewman’s can carry out an external Structure Only Survey for you free of charge in most instances to give advice and a solution as well as specify any structural works which may be required. General maintenance of your property will prevent your building suffering from Penetrating Damp. The best place to start with Penetrating Damp is of course on the outside, Prevention is better than Cure. You should check the condition of your pointing to ensure it is in good condition with no missing mortar or loose sections, If there is ensure the pointing is replaced. This is a perfect starting place for damp to enter into the wall. [![Missing Mortar](https://newmans.com/wp-content/uploads/Missing-Mortar-460x345.jpg "Missing Mortar | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/Missing-Mortar-460x345.jpg)Missing MortarCheck the condition of the face of the bricks, if some are spalled or the faces look as though they have worn away it is important they are repaired or replaced as the brickwork behind the brick face is even more porous than the brick face. Newman’s carry out vast amounts of re-pointing from patch repairs the complete elevations including brick repairs and replacement to ensure water tightness and restore the aesthetics to the property.

Following a vast amount of research and development and mentorship from one of Europe’s leading repair mortar chemists, the late Heinz Jahn, we developed our own range of repair mortars, which led to the creation of our sister company [Steadfast Specialist Products](https://steadfastspl.com/) in 2016. Further research led us to Kimia, an Italian company, who since 1979 Kimia have been specialising in the research, development, and manufacture of products specifically for the stabilisation, restoration and repair of historical buildings and monuments. Based in an earthquake prone area has acted as a key motivation for Kimia to create repair systems and solutions to not just sympathetically restore, but also to protect against future movement caused by seismic activity. Steadfast now partner with Kimia on the development of new products. This and other manufacturing partnerships means that Steadfast now supply a wide range of high-quality products to the structural repair and building restoration industry. Within Steadfast’s customer base, there are several companies and technicians that are specialists in their fields and that we know can be trusted to carry our repairs to a high standard.

If left unaddressed, wall tie failure can cause further structural damage and even result in the collapse of the outer wall. Helical wall ties provide a quick and efficient solution and often result in an almost invisible repair. Cavity Walls were introduced in the very late 18th and early 19th centuries to stop the penetration of moisture into the internal skin of masonry. When cavity wall construction began the inner and outer walls were tied together using randomly placed bricks or stones. This method was quickly phased out with the introduction of iron fishtail ties. However, iron cavity wall ties are prone to defect, as moisture penetrates the outer skin through failed pointing and cracked masonry, the ties corrode and rust which causes them to swell. This results in horizontal cracking within the bed joint which severely weakens the structure and increases the risk of collapse where the external wall moves away from the internal wall. [![Corroded Cavity Wall Tie](https://newmans.com/wp-content/uploads/2024/06/Corroded-cavity-wall-tie-300x300.jpg "Corroded Cavity Wall Tie | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/2024/06/Corroded-cavity-wall-tie.jpg)Corroded Fish Tail Wall TieInstallation of remedial wall ties is carried out by drilling a small pilot holes in the brickwork and pre-determined locations. Stainless steel, helical wall ties are then hammer driven into the pilot hole, reconnecting the inner and outer leaves. The small hole is then filled with colour matched brick repair mortar to provide an invisible repair. Being made from high-tensile stainless steel, the ties are extremely strong and will not corrode.

Unfortunately the wall ties that are used are often inadequate and the insertion of remedial timber frame wall ties is required. In the case of timber frame wall tie replacement, the self-tapping nature of the helical tie causes it to corkscrew into the timber frame providing a secure and dependable connection.

The bars are embedded into the horizontal mortar joints in the wall, using purpose made grout. This tried and tested method of repairing cracks in walls is designed to reconnect the masonry on either side of the crack, restoring the wall’s structural integrity. Depending on the existing mortar, Newman’s use either cementitious or lime-based grout. This enables us to use helical crack repair on historical and even listed buildings. Cracks in brickwork and masonry can be caused by a number of factors. These include, but are not limited to, thermal movement, failed drainage, poor construction, installation of replacement doors and windows, and vegetation such as tree roots. The shape and direction of cracks can offer clues as to the cause of cracking. Horizontal cracking, tapered cracks, cracks that follow the bed joints around the bricks and cracks through bricks, are all tell-tale signs that an experienced structural surveyor will use in both diagnosing the cause and specifying the repair. ### Crack Stitching Crack repair is carried out using short lengths of helical bar, commonly one metre long. These are installed into the horizontal mortar joint reconnecting the masonry on either side of the crack. Ideally, the bar is inserted centrally across the crack, with 500mm of masonry on either side. Bar will be inserted every four or five courses of brickwork, depending on the length of the crack. ### Bed Joint Reinforcement Where there is extensive cracking or multiple cracks along the same horizontal plane, long lengths of helical bar are used to create masonry beams. As well as reconnecting the masonry on either side of the cracks in the wall, masonry beaming redistributes the vertical structural loads across the width of the beams. In severe cases, long lengths of helical bar can be used to wrap around the building, reinforcing the entire structure. In cases where subsidence has occurred, the introduction of the helical system can minimise the need for piling or underpinning. Masonry beams can also be introduced to allow for the safe removal of doors, windows and even masonry during renovation projects. ## Crack Repair Video ### Combined Methods Using Bed Joint Reinforcement and Crack Stitching combined with other helical ties and repair strategies, we are able to provide a permanent repair solution for [lintel failure](https://newmans.com/services/building-and-structural-repairs/lintel-repair/), [lateral restraint](https://newmans.com/services/building-and-structural-repairs/lateral-restraint/), [retaining and boundary wall restraint and repair.](https://newmans.com/services/building-and-structural-repairs/retaining-and-boundary-wall-repairs/) Importantly, the installation process is far less intrusive than traditional methods, such as take down and rebuild, often allowing the premises to remain occupied. Disruptive removal and re-build techniques are often avoided by the introduction of helical bar, and the aesthetics of the damaged structure are retained. This method of repairing cracks in masonry is especially suited to listed buildings and in applications where it is not practical for new materials to be used. The repairs are hidden in the bed joint and, once re-pointed or rendered, provide a maintenance free, aesthetically pleasing repair that is often unnoticeable. #### Repair Specification and Quick Estimate Based on a full description of the issue and sufficient images, it may be possible for one of our surveyors to provide a repair specification and estimated cost.

Due to thermal and seasonal movement long walls without movement or expansion joints will suffer frequent cracking. It is therefore vital that expansion joints are created to prevent cracking by allowing for this movement to take place. Newman’s create movement joints in existing masonry by cutting through the outer skin in a cavity wall or half way through if a solid wall and inserting a foam backing cord. Helical, retrofit wall ties are installed connecting the inner and outer skin of masonry in conjunction with helical slip ties and then a polysulphide mastic is injected and finished to give an aesthetically pleasing finish. Newman’s specialise in the process of creating remedial movement joints and offer a ten year guarantee for all repairs. #### Repair Specification and Quick Estimate Based on a full description of the issue and sufficient images, it may be possible for one of our surveyors to provide a repair specification and estimated cost.

Lintel failure is a common problem in properties of all ages and all types of lintels. It is especially common in Victorian properties and can pose serious threat to safety. Brick Arch and Soldier course lintels in period properties can fail and sag causing the masonry above to drop and crack losing all structural integrity, over time will become worse and has the potential for collapse. Lintel failure often appears after the replacement of windows and is caused by the removal of load bearing windows that are replaced with non-load bearing windows such uPVC causing failure. It is also common to have historic settlement of the lintel which may go un-noticed or not be deemed as a serious defect, which is often not the case. In the majority of cases lintel repair is straightforward using [Bed Joint Reinforcement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-crack-repair/) and pinning ties, combined with resin injection systems which restore the structural integrity of the lintel whilst retaining the aesthetics of the facade. Newman’s work in partnership with contractors carrying out window replacement schemes for private clients and social housing offering fast cost saving solutions allowing the safe removal of windows and doors. As a leading specialist Newman’s are able to offer 10 year guarantees on all lintel restoration design schemes. #### Repair Specification and Quick Estimate Based on a full description of the issue and sufficient images, it may be possible for one of our surveyors to provide a repair specification and estimated cost.

We use a combination of traditional techniques and modern methods of repair. Foundation failure mainly occurs because of subsidence and poor construction and not so common “heave”. The cause of subsidence varies but it is often caused by changes in the moisture of the soil that the foundations are built on. Failed drains, changes in the water table and poor soil conditions are all contributory factors. Mature shrubs and trees within close proximity to the structure can increase the risk of subsidence by rapidly removing excessive amounts of moisture from the ground during dry spells. Foundations can be repaired using micro-piles or shire piles, which provide fast and unintrusive methods of repair, or by means of traditional underpinning.

The system fundamentally comprises of a stainless steel rod embedded inside a fabric mesh that is pressure injected with cementitious grout installed in an oversized core hole which expands like a balloon, gripping into voids in the substrate and creating a bond with the parent material. Sock anchors are particularly effective in repairing rubble-filled walls and can be used to reconnect failed or separated masonry, in arches, bridge strengthening, stabilisation and many more applications. This method of repair is ideally suited to listed buildings and aged structures such as bridges, manor houses, tourist attractions, churches, cathedrals and high rise building etc. It is possible to use the cored material to reinstate the hole drilled providing an aesthetically pleasing repair that will go unnoticed. #### Repair Specification and Quick Estimate Based on a full description of the issue and sufficient images, it may be possible for one of our surveyors to provide a repair specification and estimated cost.

Lack of lateral restraint will be presented by ‘bowing’ or ‘bulging’ walls. It is often found that there is absolutely no Lateral Restraint or connection to the floor and ceiling joists causing the masonry to move outwards weakening the structure with the potential for collapse. Bay windows, especially in Victorian properties, are commonly found to have no connection to the existing structure and are built on shallow foundations resulting in extensive outward movement requiring the need for lateral restraint. End of terrace gable and flank elevations are also commonly affected by lack of Lateral Restraint as the floor and ceiling joists run parallel to the masonry with no form of tying in or restraint allowing outward movement and cracking to occur. Newman’s can restrain any further movement by tying the masonry to floor and ceiling joists as well as partition walls using lateral restraint ties. This process is unintrusive and once the making good has been carried out the repairs will be almost invisible. Common solutions such as the use of batt straps alone should not be relied upon to provide the restraint required. As a leading specialist Newman’s are able to offer 10 year guarantees on all lateral restraint design schemes. #### Repair Specification and Quick Estimate Based on a full description of the issue and sufficient images, it may be possible for one of our surveyors to provide a repair specification and estimated cost.

A Structural Survey is a visual survey carried out by a suitably trained surveyor who will examine the internal and external structure of the property to assess any defects that are present or potential. We will assess the the materials used to construct the internal and external walls and we will also inspect the foundation if safe to do so. ## Our surveyors have extensive knowledge in identifying movement such as: [Subsidence and Heave](https://newmans.com/services/building-and-structural-repairs/foundation-repairs/) [Lintel Failure](https://newmans.com/services/building-and-structural-repairs/lintel-repair/) [Outward Movement/ Bowing Walls](https://newmans.com/services/building-and-structural-repairs/lateral-restraint/) [Thermal Movement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-crack-repair/) [Wall Tie Failure](https://newmans.com/services/building-and-structural-repairs/wall-tie-replacement/) Differential Movement etc. Your Structure Only Report will contain a detailed written assessment on the cause of the movement and will specify the remedial treatments necessary to prevent further movement as well as a repair specification. The report will also contain information regarding the construction of internal and external walls and how their performance will be affected in the future. The report is provided in a PDF format with drawings identifying the defects and a specification of the remedial measures required. --- ### [Facade Maintenance](https://newmans.com/services/facade-maintenance/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** [Home](https://newmans.com/ "Home") » [Structural Repair Services](https://newmans.com/services/ "Structural Repair Services") » Facade Maintenance ## Brick & Stone Restoration, Cleaning & more Newman’s specialise in façade maintenance including brick and stone restoration, cleaning, tinting and repointing. ![Facade Before and After Repairs and Restoration](https://newmans.com/wp-content/uploads/2016/08/BeforeAndAfterRepairsRestoration-300x112.jpg "Facade Before and After Repairs and Restoration | Newman's - Structural Repair Specialists") ### Services include: - - **[DOFF Cleaning](https://newmans.com/services/videos#doff_cleaning)** – steam based cleaning. Highly effective yet sympathetic to the material being cleaned. - - **[Dust Free Blasting](https://newmans.com/services/Brick-Facade-Maintenance/Facade-Cleaning)** – often referred to as sandblasting. - - [**Brick and Stone Restoration**](https://newmans.com/services/brick-tinting/) – using state of the art repair products that replicate the properties of the original material. - - **Stucco Repair** – stucco is a durable, decorative wall surface that can develop cracks and holes over time. When cracks and holes appear in stucco it is important to seal them quickly to protect from the damage of water ingress. Our technicians use specialist stucco repair mortars to repair and replace stucco and to reform detailed profiles. - - **Repointing** – Including Chimney Repointing – As well as being unsightly, failed or damaged pointing can lead to more severe problems such as damp penetration, frost damage and even collapse. The appropriate selection of materials is critical and should be left to professionals. We ensure that the correct material is used and that the final finish matches the existing mortar. Using our mortar tinting process we are also able to recolour existing mortar where required. - - **[Brick Tinting](https://newmans.com/services/Brick-Facade-Maintenance/brick-tinting-and-repairs)** – using our proprietary tinting technique we can recolour brick, stone, concrete, roof tiles and any permeable building material. - **Brick and Façade Waterproofing** – We use a breathable, water repellent surface treatment to protect walls from damp penetration. Once dry, our waterproofing treatment is transparent and does not colour the surface. However, with the inclusion of our natural tinting pigments, waterproofing and tinting can be combined. --- ### [Brick Tinting & Restoration](https://newmans.com/services/facade-maintenance/brick-tinting/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** [Home](https://newmans.com/ "Home") » [Structural Repair Services](https://newmans.com/services/ "Structural Repair Services") » [Facade Maintenance](https://newmans.com/services/facade-maintenance/ "Facade Maintenance") » Brick Tinting & Restoration ## Brick Restoration Over time bricks can become damaged by the elements, erosion and impact. When repairing bricks it is vital that the repair material used has the same properties as the original. Bricks that are repaired with unsuitable material such as sand and cement may look okay but over time can lead to problems with cracking and damp. Newman’s craftsmen carry out brick restoration using specialist, mineral, brick repair mortars that replicate the properties and colour of the original material. Textures and shapes are replicated using a range different tools and techniques. ## Brick Tinting Finding the correct bricks when extending or carrying out remedial works is an increasingly difficult task and reclaimed bricks are rarely available in sufficient quantities. Therefore brick tinting, a process of dying bricks to match, is often the best solution. Combining natural colour pigments with a vapour permeable or ‘breathable’ fixing agent provides a permanent, colourfast stain that is not lost to weathering or UV exposure. Once applied there is no ongoing maintenance. A water-repellent, breathable fixing agent can also be used where required. In order to obtain a complete, uniform finish, existing brickwork can be cleaned prior to tinting or the tinting can emulate weathering or sooting. Because brick tinting stains the bricks it doesn’t change the texture and provides a much more sympathetic solution than painting or rendering methods that are often used to overcome mismatched bricks. A specialist will match the colour required without using the fixing agent. The samples can then be power-washed off. Once a colour match has been made, the tint is created using the fixing agent which bonds the tint permanently to the brick. Tinting, which is also referred to as brick dying and brick staining, can be used on any porous building material and we are also experienced in Stone Tinting, Roof Tile Tinting and and Mortar Tinting. --- ### [Balcony, Walkway & Step Waterproofing](https://newmans.com/services/balcony-and-walkway-repairs/balcony-walkway-waterproofing/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** [Home](https://newmans.com/ "Home") » [Structural Repair Services](https://newmans.com/services/ "Structural Repair Services") » [Walkway, Step & Balcony Repair](https://newmans.com/services/balcony-and-walkway-repairs/ "Walkway, Step & Balcony Repair") » Balcony, Walkway & Step Waterproofing ## Balcony, Walkway & Step Waterproofing Keeping balconies, walkways and steps completely waterproof is essential in preserving and protecting the materials that they are constructed from. Any moisture penetration will cause structural defects to the surface and supports regardless of the materials used and will also become a safety hazard. Newman’s are one of few UK based companies using the latest PMMA (Poly methyl methacrylate) Waterproofing products from Vulkem and Resiplast. Repairing leaking balconies, steps and walkways used to be a highly disruptive process which often meant the area would not be accessible for a lengthy period of time causing disruption to tenants. Newman’s use the unique PMMA liquid membrane waterproofing system which is cold applied, thereby alleviating the need for heating bitumen and the use of roofers’ torches. Once installed, the modified polyurethane system has a setting time of just one hour. The installation process is fast and provides a completely waterproof surface. The concrete sealing system which comprises of a primer suitable for the existing surface and conditions, a waterproof liquid membrane and a durable top coat that protects against wear and UV, comes in a huge range of colours and can be topped with a wide range of finishes. The benefits of using the Vulkem and Resiplast waterproofing systems are: - 100% Waterproof - Can be applied over almost all existing substrates - A range of colours and aesthetically pleasing finishes can be achieved - Cold applied no hot works required - Rapid setting times - Can be applied in low winter temperatures The PMMA system is unique with nothing else like it available on the UK market and can be applied for various applications such as balcony, step and walkway refurbishment, stadiums, roof tops, warehouses, runways, car parks to name but a few applications.

These techniques are cost effective and provide permanent solutions to cracking and other building defects. Cracks in walls are caused by a number of structural defects and problems. Although it is often thought that subsidence is the most common cause it is actually rarely the case. Seasonal changes, vegetation, replacement doors and windows, failed or inadequate drainage are just a few reasons that cracks in buildings can occur. Click on the areas indicated in the image below to view a selection of our structural repair services. Cracks in walls are a common problem and are caused by movement of one form or another. The pattern and location of a crack in a wall can often point to its cause. Newman’s are highly experienced crack repair specialists. We survey, assess and diagnose the cause of cracking and propose appropriate crack repair techniques. Cracks often appear on period properties and when inspecting your own property you should check for cracks above doorways, cracks above windows, cracks in ceilings, cracks in plaster and cracks in render. Cracks in walls above doorways and cracks above windows are normally linked and could be a sign of lintel failure and will need to be inspected to ensure it is not subsidence as the crack pattern is often similar. Cracks in ceilings and cracks in plaster are often linked to outward movement caused by a lack of connecting ties into the floor joists and wall junctions and again a competent surveyor from Newman’s should inspect this. There are other causes of cracking such as thermal movement, subsidence, heave, wall tie failure to name a few. #### Repair Specification and Quick Estimate Based on a full description of the issue and sufficient images, it may be possible for one of our surveyors to provide a repair specification and estimated cost.

As well as being an eyesore, steps, balconies and walkways can become unsafe requiring the services of a specialist contractor to design and implement a balcony repair programme to restore the structural integrity of the balcony and/or restore the walkway. To repair concrete or stone balconies and steps suffering from cracking, honeycombing of concrete, concrete cancer, stone failure etc, it is essential that repairs are carried out using the correct repair mortars and [waterproofing](https://newmans.com/services/balcony-and-walkway-repairs/balcony-walkway-waterproofing/) systems. We employ high quality products such as the Jahn range of repair mortars and the Resiplast and Vulkem PMMA waterproofing systems which we believe to be the best products currently available to the UK market. The majority of the problems associated with Concrete Failure to balconies are associated with the penetration of moisture which is often caused by the concrete being exposed to the elements and requires complete concrete repair and waterproofing. Most waterproofing systems require long periods of time free from traffic in order to prime the surface and to apply a waterproofing system to seal the surface, which in most cases isn’t practicable. Newman’s are one of a few UK structural repair companies to have met the high standards set by Vulkem who have manufactured and developed a system that is cold applied and 100% waterproof within 1 hour of application and can be walked on within 1 hour after the finished installation. The Vulkem system is a cold applied PMMA liquid membrane that is applied onto the existing surface, trowelled and levelled and can be finished with a wide range of products to provide an aesthetically pleasing, durable repair which is 100% waterproof and we can offer a 20 year guarantee.

When a retaining structure fails the effects can be devastating causing the risk of collapse not only to the wall but also to the structure built on the ground the wall is retaining. Newman’s can reinstate the structural integrity of retaining walls with the introduction of Ground Anchors combined with the helical bar reinforcement systems. Capable of handling loadings of up to 200kn’s, ground anchors combined with deep helical masonry beams offer a permanent guaranteed retaining wall solution. Boundary walls, are of little structural importance but they are unpleasing to the eye when they fail and they pose the risk of collapse. They can be easily repaired without the need for costly rebuilds by introducing the [Bed Joint Reinforcement](https://newmans.com/) system. By using modern methods of masonry repair, Newman’s are able to offer vast savings in cost and time in comparison with traditional methods of rebuilding the failed structure such as taking down and rebuilding. Lack of movement joints is a common cause of cracking in both retaining and boundary walls, especially in walls of greater length. Remedial movement joints can be created using a combination of vertical cuts, wall ties, slip ties and silicone sealant. Our engineers provide a full design service giving detailed specifications and calculations and technical drawings. As a leading specialist Newman’s are able to offer up to 10 year guarantees on all restraint design schemes. #### Repair Specification and Quick Estimate Based on a full description of the issue and sufficient images, it may be possible for one of our surveyors to provide a repair specification and estimated cost.

We offer concrete repair surveys and issue detailed written reports with repair diagnosis and method of repair. Concrete can fail and become defective losing all structural integrity due to physical measures such as vibration and impact, freeze-thaw action, salt crystal expansion and erosion as well as mechanical defects such as alkali aggregate reaction and chemical exposure. Reinforced concrete can fail for various reasons such as carbonation – where Carbon Dioxide (CO2) that naturally occurs in the atmosphere, reacts with the calcium hydroxide. Corrosion of the reinforcing due to stray electrical current that can travel through the reinforcement and the presence of corrosive contaminants such as chlorides accelerate the corrosion dramatically. Newman’s work closely with the industries leading concrete repair manufacturers and employ highly skilled tradesmen to carry out concrete repairs. Repair of the damaged structure can be treated by removing local areas of the damaged concrete and treating any defective reinforcing with a specialist primer protecting from further corrosion restoring the structural integrity. Reinstatement of the concrete surface is often carried out by hand using high strength repair mortars. As approved contractors for the largest manufacturers in the concrete repair market, we can offer the solutions for all concrete repair problems. From large scale renovations and structures, to restoring kerbs and joint rises, Newman’s will have a product or system to do the job. Products include but are not limited to: • Primers & steel protection • Cementitious repair mortars • Resin repair mortars • Crack injection and stitching materials • Fast setting pavement repairs • Decorative coatings • Anti-carbonation coatings • Concrete resurfacer [Click here](https://newmans.com/case-studies/balcony-repairs---old-fire-station-hammersmith "Balcony and Walkway Repair - Old Firestation, Hammersmith") to see a case study on the repair of the concrete balconies and walkways to the Old Fire Station in Hammersmith. or click below to download a PDF. --- ### [Wall Tie Survey](https://newmans.com/services/property-surveys/wall-tie-survey/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** ### What is a Wall Tie Survey? A wall tie survey is a specialist survey which should only be carried out by suitably trained and experienced surveyors, who will assess whether the wall ties present within the structure are doing their job properly, tying the two leaves of masonry adequately. We offer intrusive and nonintrusive wall tie surveys. Where wall ties are inadequate or corroded we will recommend [wall tie replacement](https://newmans.com/services/building-and-structural-repairs/wall-tie-replacement/). ### What are the Differences Between an Intrusive Survey and Non-intrusive Survey? **Intrusive** surveys are generally required when the cavity cannot be exposed and the wall ties cannot be inspected through an endoscope or fibre optic camera. This is usually a necessary requirement when cavities have been injects with cavity wall insulation as the tie will be covered. Intrusive surveys require the ties to be located and bricks removed to expose the tie to allow a visual inspection of to be carried out. **Non-Intrusive** surveys can be carried out when it is possible to see inside the cavity through an endoscope or fibre optic camera. We can achieve this by locating the tie and drilling a series of 8mm holes to allow the insertion of an endoscope or fibre optic camera. As with both surveys each panel is inspected and all the ties will be located to ensure there is adequate wall ties within the panel to ensure the requirements of BS:5268. ### What is a Wall Tie? And Why Do I Need Them? A wall tie is a simple solution that wall tie the two leaves of masonry within a cavity wall together but also allow them to move independently and transmit live and static loads across the structure without substantial movement or deformation of the façade. Wall ties are a vital structural component and are often not picked up within homebuyer surveys often leading to costly repairs that are unforeseen during the sale of the property. ### What is The Worst Possible Scenario? Wall ties form a vital structural component of any structure but unfortunately due to bad building practice etc, they are often inadequately placed and in coastal areas corrosion of wall ties is imminent and should be inspected. Failure of wall ties has led to the collapse of masonry panels leaving structures unsafe with the potential for collapse. --- ### [Property Surveys](https://newmans.com/services/property-surveys/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** ## Surveys ### What type of Surveys Are Available? #### [Structure only](https://newmans.com/services/structure-only-report/) This is a visual inspection offering advice on the materials used to construct the property, how they will perform in the future. It covers any structural defects present and will provide advice on repair. This type of survey is cheaper than a full structural survey as it is limited in its scope. #### [Wall Tie Survey](https://newmans.com/services/wall-tie-survey/) A wall tie survey is often carried out to assess the state of the wall ties that tie the structure together. Often it is found that there are inadequate wall ties or in fact corroded wall ties that are likely to fail putting the structure at serious risk. We offer an intrusive and un-intrusive survey to provide a detailed written report along with repair specification. #### [Rope Access Survey](https://newmans.com/services/rope-access-surveys-and-repairs/) All of our survey service can be carried out by abseil where appropriate. --- ### [Accreditations](https://newmans.com/accreditations/) **Published:** August 2, 2016 **Author:** Support Department **Content:** # Quality, Professional, Approved We are approved, registered contractors for leading manufacturers and suppliers to the building and structural repairs industry.

Our surveyor attended the property within 24 hours of the initial contact to out the home owners mind at rest and carry out a structural survey to investigate the cracking and design a **[Structural Repair](https://newmans.com/services/building-and-structural-repairs)** solution. The property was suffering from **[Lintel Failure](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure)** which was causing sagging of the brickwork above the rear door opening with diagonal stepped cracks. Diagonal cracks above doors and windows are a common sign of **[Lintel Failure](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure)**. The front right hand corner had a vertical hairline crack running from the dam proof course up to the first floor panel. We were un-certain that the cracking was historic as there was very little debris in the cracks so our engineer opted that we installed a remote crack monitoring system to monitor the movement for three months so that we could implement the correct repair system. Once the data from the remote monitoring unit had been interpreted we found that there was very slight movement and a Twistfix Helical repair solution would prevent further cracking. **[Bed Joint Reinforcement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2)** was used to create Masonry beams that were installed above the rear door opening which distributes the loads across the masonry which in turn creates load bearing beams within the masonry alleviating the need to remove and rebuild the lintel and the masonry above. Twistfix helical bar encompassed in WHO-60 thixotropic grout,creating masonry beams, has been tested by the BRE and achieved loads of up to 32.8 kN/m. The rotating corner was stitched using Twistfix crack stitches tying the cracked masonry together and reinforcing the bed joint preventing further rotation and resisting separation of the vertical crack. Once the Twistfix helical system was installed the structural movement was restrained and a 10 year IGL **insurance backed guarantee** was issued against further cracking.

The engineers report stated that the lintels over the central panels of the bay had cracked vertically/diagonally, both above the ground-floor and first-floor windows. There was no significant cracking in the brickwork above the ground-floor lintel, and only a 0.5mm-wide crack in the gable masonry. There were no signs of significant distortion such as would indicate that subsidence had taken place. In the ground-floor lintel the north part of the lintel had rotated slightly anticlockwise and had dropped by 5-10mm relative to the south part. The cause of the cracking could not be fully determined but was deemed to be due to the low tensile strength of the lintels and relatively historic. Although it had been repaired cosmetically, no structural repair had been carried out. Following several recommendations from the structural engineer, the property owner chose a solution utilizing helical bar reinforcement and contacted Newman’s. Following a visit by one of our surveyors, a repair scheme was designed as per the structural repair drawing below. #### Repair Method To repair and strengthen the [lintels](https://newmans.com/services/building-structural-repairs/lintel-repair/), twin bands of Steadfast’s Helicalfix high tensile strength, stainless steel helical bar were installed. The bars were installed horizontally, into the bed joints between the floors, across the entire width of the bay, to reconnect the cracks and redistribute the structural loads. The cracks in the brickwork were repaired using single bands of [Helicalfix crack stitching bars](https://steadfastspl.com/product/helicalfix-crack-stitching-bars/). The shorter lengths of stainless steel helical bar are inserted horizontally into the bed joint across the cracks, reconnecting the brickwork on either side. [Grouted helical ties](https://steadfastspl.com/applications/pinning-masonry-arches-grouted-ties/) were then installed vertically to reconnect the lintels to the masonry above. Although not reflected in the photos, all areas of masonry and mortar disturbed during installation were made good to provide an almost invisible repair that the client was very pleased with. --- ### [Listed Building Refurbishment North London](https://newmans.com/case-studies/listed-building-refurbishment-north-london-job-no-1930/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Mymms Hall, on the outskirts of North London, is a grade II\* listed building which dates back to the earl 16thcentury. In the past additions have been added to the building as well as a late Victorian annexe which had all fallen into a state of disrepair. Newman’s being a specialist in restoring the external envelope of listed buildings and period properties, were consulted at the initial stages of the design and refurbishment to this listed building and were asked to design a suitable scheme to repair and restore the exterior of this beautiful building. A modern approach was required in order to conserve and restore the property effectively without any unnecessary disruption to the external structure and with as little damage to its aesthetics. We carried out soil investigations and, as expected for a property of this age, the foundations were inadequate. With soil samples lab analysed it was agreed with the structural engineer that an underpinning or piling scheme wouldn’t be required and that reinforcement to the superstructure would suffice. Almost all of the lintels had failed to the entire building causing stepped diagonal cracking in between window heads as well as cracking and separation across the rest of the building which had been caused by excessive ground movement and increased loads. Ivy and other vegetation had previously grown all over the building and It was deemed necessary to remove the vegetation as root ingress had added to the structural instability by eating the cracks and gaps in between brickwork cause excessive failure of the pointing. Being a period property originally constructed using lime putty mortar it was essential that all products used to reinforce the brickwork were lime based and provided a sensitive approach to the restoration scheme. Our engineers designed a scheme that combined over 500 metres of Twistfix [bed joint reinforcement](https://newmans.com/services/building-structural-repairs/bed-joint-reinforcement/) to create ‘helibeams’ within the masonry to increase the brickworks load bearing capacity, distribute structural loads across the façade and tie all cracked brickwork. As the building was being re-pointed with lime putty mortar it was essential we didn’t use structural grouts or resins that would create hard spots which would lead to further cracking and movement. Areas where ground movement had been excessive, had caused major cracking to the brickwork and again Twistfix 2nd generation bed joint reinforcement was selected to distribute structural loads and resist further cracking should ground settlement occur in the future. A lime based grout was used to provide the required fixing for the Twistfix bed joint reinforcement as well as provide the necessary stabilisation to the brickwork during the repointing process. The entire building required repointing with lime putty mortar, with bed joints of irregular width and very delicate masonry the extraction of mortar had to be carried out in the traditional manner; by hand. The process is very time consuming but once re-pointed with heritage mortar the reinforcement to the brickwork was invisible and the external envelope was fully restored and set to withstand another century.

We were contacted by a very worried home owner whose thoughts were that their house may fall down and can we help? Our office in Guildford work with many residential home owners who have purchased these elaborate Victorian properties and are experienced in diagnosing suitable repairs that will provide a long term solution yet won’t cause major long term disruption. Cracking was evident to the internal party wall as well as cracking and sagging of the brickwork externally to the front elevation. Cracking of this nature is common in Victorian period properties and is caused by a lack of connection between the brickwork to the front and the brickwork of the party walls. It is essential to reconnect the two panels of masonry so that they can no longer separate. In order to achieve this connection Twistfix bed joint reinforcement was selected to provide a connection between the two elevations but also resist further outward movement. Areas of masonry that had sagged beyond repair were carefully removed and re-built using reclaimed bricks and mortar that matched the existing. Our delicate approach to re-building period masonry ensures that we retain the original aesthetics of the proeprty. The bed joint reinforcement is chased into the external bed joints of the front elevation and then drilled into the internal party wall where it is chased into the wall. This method of repair creates a L shaped tie which when grouted into the slots achieves exceptionally high pull out resistance. The bressumur beam supporting the first floor joists above the bay window opening had also snapped in half requiring immediate repair. A team of carpenters reinforced the bressumer beam and Newman’s were required to design a solution that would take some of the load off of the bressumer beam. Again Twistfix Bed Joint Reinforcement was used to distribute loads across the masonry and reinforce the brickwork to spread the load evenly across the bressumer beam. The Bed Joint Reinforcement was installed in pairs to create masonry beams that distribute structural loads. The works restored the structural integrity of the masonry and provided a permanent connection between the bowing walls in the least disruptive way. Modern methods of masonry repair and reinforcement are preserving period properties and ensuring the heritage remains in the structure. **Newman’s can help to diagnose structural defects, cracking and movement by arranging a free Structural Survey, contact London and the south East’s leading structural repair specialists for Help, Advice and peace of mind Call 0333 444 0154 or Email info@newmans.com** --- ### [Structural Repair - Oxford](https://newmans.com/case-studies/structural-repair-oxford/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** This block of garages in Oxford, owned by Oxford City Council, had lost all structural integrity to the flank elevation causing immediate concern for the safety of the garage owner and passers-by who had noticed severe cracking and distortion to the brickwork at high level. A fast response was required by Newman’s in order to design and implement a **[Structural Repair](https://newmans.com/services/building-and-structural-repairs)** solution that would prevent further **cracking** to the brickwork without major disruption. As well as preventing disruption it was essential that the **Structural Repair** solution was to be cost effective also. Surveyors from our offices in **Oxford** attended site as soon as the enquiry had come to us and we quickly diagnosed the cause of cracking to the structure and were then able to design a suitable scheme of **Structural Repair**. Being a [**Twistfix**](http://www.twistfix.co.uk/) approved designer and installer our **Structural Solution** utilised their innovative range of products to reinforce masonry without the need for re-building brickwork. In this instance we specified the use of their 7mm helical wires installed within the bed joint to reinforce and reconnect the separated masonry. In order to reinforce the brickwork and connect the separated masonry our technicians chase slots into the mortar between the brickwork to a depth of approximately 40mm, the bed joint is then flushed with water to ensure all dust is removed from the joint. Twistfix’s WHO-60 high strength grout is then pressure injected into the slot and the helical wires are inserted into the grout. A final layer of grout is then pressure injected leaving a 15mm recess for re-pointing of the mortar. This method of **[Masonry Repair](https://newmans.com/services/building-and-structural-repairs)** is called **[Bed Joint Reinforcement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2)** and is a fast and effective way of restoring the structural integrity of the masonry. Using this method of repair saves the need for the removal and re-building of the failed masonry, which in this instance would have been extremely costly for the client who would have had to partially remove the roof in order to carry out rebuilding of the supporting wall. Our repairs can be guaranteed for up to 20 years by a genuine insurance backed guarantee ensuring that a modern approach of repair is also a lasting approach.

Chloride attack had caused extensive cracking to this reinforced concrete block of residential properties putting the structure into high risk of further structural issues as well as water ingress. As well as structural defects and water ingress falling concrete poses a severe risk to the health of the residents and passers-by and required immediate attention. Chloride Attack poses severe threat to the integrity of reinforced concrete structures and particularly those in marine environments such as this block being only 30 metres from the sea front. Chloride Attack occurs when salts and other contaminants are absorbed by porous concrete. A chemical reaction then occurs within the concrete that causes hydrochloric acid that eats away at the steel causing the steel to corrode and expand spalling the concrete. Catastrophic loss of structural integrity can occur as a result of chloride attack and it is essential that marine structures are protected as best possible to prevent chloride attack occurring. Porous concrete will suffer at an enhanced rate as opposed to concrete with pores which are small and any surface defects such as minor cracking or spalling can lead to severe problems. In this instance chloride attack had caused major spalling and in some areas the concrete had blown away so much so that all of the reinforcing rods were exposed accelerating the rate of attack leading to severe concrete failure. Our surveyors designed a suitable repair solution using the Flexcrete concrete repair system in order to repair the corroded steel and reinstate the areas of spalled concrete. By breaking out the failed concrete and exposing the steel we were able to treat the steel by abrasive blasting to remove all corroded steel. In order to treat the corroded steel a 20mm coating of Flexcrete steel reinforcement protector was applied around all of the corroded steel which will prevent Chlorides from attacking the steel. Due to the concrete being fairly porous Flexcrete bonding bridge slurry was applied to the existing concrete to provide a good bond between the existing concrete and new repair mortar. In some instances the repairs to pillars and beams were in excess of 150mm deep and Flexcrete Monomix excelled in overhead repairs allowing us to carry out a fast and effective repair. With the steel treated and the repair mortar installed we used Flexcrete monolevel fairing coat mortar to seal all pores within the new repair mortar and provide a smooth flush finish ready for decoration. Flexcrete Anti carbonation coatings were then applied in order to provide a decorative finish but also to protect the concrete. Flexcrete’s monodex ultra is a high performance coating that resists carbon attack and aids in the prevention of chloride attack. With a system solution we were able to provide a 10 year guarantee on to the areas of repair covered by the manufacturer and also our own independent insurance backed guarantee.

With a vast amount of London’s housing being classed as a period property it is no wonder that Newman’s are regularly carrying out **[Structural Repairs](https://newmans.com/services/building-and-structural-repairs)** to repair **Structural Defects** such as **Lintel Failure**, **Bowing Walls**, Bay Window Restraint and general cracking. Newman’s were once again called upon to carry out a **[Structural Survey](https://newmans.com/services/Property-Surveys/Structure-Only-Report)** to a 5 storey Victorian house in Islington, North London which was suffering from a range of Structural Defects causing the property to crack on the front and rear elevations. We carried out CCTV drain inspections to assess whether ground movement had occurred due to a drainage failure which confirmed that there weren’t any issues with the drainage washing away the soil below the foundation. The front elevation was suffering from **[Lintel Failure](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure)** which caused the masonry to bow and pull out from the main structure. As well as **Lintel Failure** localised cracking had occurred to the brickwork supporting the steps into the property. Twistfix **[Bed Joint Reinforcement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2)** was installed above areas of **Lintel Failure** which creates lintels in the bed joint that allows us to create load bearing beams without the need for the removal of the existing failed lintel. Cracking to the steps was repaired and restrained with the installation of Twistfix crack stitches which is again another method of bed joint reinforcement and stitches both sides of the separated masonry together and resists further separation. In some instances it is not possible to install helical bar we utilise the Twistfix patented 450mm pinning tie to resist further cracking. The Rear Elevation had suffered with **Lintel Failure** also but combined with **Outward Movement** the cracking was much more severe. The masonry had bowed due to there being very little connection between the floor joists and the masonry. This is very common in properties of this age and often it is considered that a rebuild is the only option. Using Twistfix **[Lateral Restraint](https://newmans.com/services/building-and-structural-repairs/lateral-restraint)** ties we are able to provide a mechanical connection between the external masonry and the floor joists which will resist the **Outward Movement** and leave an almost invisible repair. As well as tying into the floor joists cracks had appeared at the junction between the external masonry and the internal partition walls and again Twistfix lateral restraint ties are used to tie the external masonry to the internal partition walls. Once the **[Structural Repairs](https://newmans.com/services/building-and-structural-repairs)** had been carried out repointing and plastering was carried out to provide an almost invisible repair. All of our works are covered by a genuine insurance backed guarantee and this project was insured against further cracking and outward movement for a period of 10 years.

The scheme was created by London’s councils in order to bring people back to the high streets and into new areas of London that tourists may not usually visit. This particular project was next to Earls Court underground station in the middle of the high street. We were instructed by the council to carry out a **[Structural Repair Survey](https://newmans.com/services/Property-Surveys/Structure-Only-Report)** to 11 properties on the high street prior to the commencement of their regeneration scheme in order to advise and provide detailed reports of the necessary repairs and produce a repair specification and estimates for the works. The building is a 4 storey building constructed in the late 1800’s with 13 inch solid walls and was suffering from cracking which was caused by **[Lintel Failure](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure)** allowing the masonry above to drop and rotate putting the building’s structural integrity at risk. **[Lintel Failure](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure)** is a common structural defect in properties of this type and Newman’s regularly repair and reinforce masonry that has failed due to [**Lintel Failure**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure). Using Modern Methods of Masonry Repair we can restore the structural integrity without the need for disruptive and costly remove and rebuild methods. Newman’s installed over 200m’s of Twistfix helical bar in order to create masonry beams within the bed joint which in effect creates load bearing lintels above the existing lintels so that they do not need to be removed and rebuilt. As well as [**Lintel Failure**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) the pointing was in a poor state of disrepair which was caused by weathering of the mortar. With the mortar being the original used when the property was built it is of no wonder that after 120 years of wind and rain it had failed. Newman’s always carry out deep bed **[Repointing](https://newmans.com/)** and remove the mortar to a depth of 45mm and inject a 30mm bead of thixotropic grout which will stabilise the brickwork and bond the masonry providing a repair that is very strong under compressive loads yet flexible so still allows the masonry to move. The stabilisation grout is then **[Re-Pointed](https://newmans.com/)** to match the existing, but in this case the client wanted the new pointing visible so that the repaired areas could be seen. As well as **[Structural Repairs](https://newmans.com/services/building-and-structural-repairs)** and **[Repointing](https://newmans.com/)** we had to remove the balustrade from the balcony and install new lead flashings along with coping stones due to the balustrade being unstable and moisture penetrating into the top flat. Once the **[Structural Repairs](https://newmans.com/services/building-and-structural-repairs)** had been carried out we decorated the front elevation providing an aesthetically pleasing and lasting stabilisation scheme.

A **[Structural Survey](https://newmans.com/services/Property-Surveys/Structure-Only-Report)** was carried out by one of our in house surveyors based in our Hammersmith office nearby as time was a key factor in the procurement of the contract which is often the case when working with contractors. Structural Defects were noted across the property and needed urgent attention to prevent extensive damage to the masonry. [**Bowing Walls**](https://newmans.com/services/building-and-structural-repairs/lateral-restraint) were evident across the gable elevation as well as [**Lintel Failure**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) and Cracking due to minor settlement of the foundations. As well as the[ **Lintel Failure**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) and Bowing of the masonry the pointing to the front elevation was in terrible condition along with spalling of the brick faces caused by moisture penetration creating a freeze thaw cycle blowing the brick faces off during the winter months. Separation of the front elevation from the gable elevation had also occurred requiring reinforcement and tying back to prevent further outward movement and twisting which has the potential to lead to collapse if ignored. Being a [**Twistfix**](http://www.twistfix.co.uk/) registered contractor we have access to a range of products which enable us to carry out modern methods of masonry repair which save time and money compared to traditional remove and rebuild techniques most trades persons prefer to adopt. The [**lintel failure**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) was repaired using 9mm Twistfix helical wire reinforcing the Bed Joint essentially creating lintels within the masonry combined with the patented 450mm CD vertical pinning ties which are installed vertically through the bricks in the lintel tying into sound masonry. The [**bowing walls**](https://newmans.com/services/building-and-structural-repairs/lateral-restraint) were tied into floor joists using Twistfix Lateral Restraint Ties which are installed through the external masonry using only a 12mm drill hole which enabled us to complete the installation of the ties within one day compared to around 3-4 days for traditional methods. [**Masonry Beams**](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2) and Crack Stitches were installed to reinforce the upper corner and to tie the front elevation to the gable elevation as well as distributing structural loads. This method of repair is often used in instances where settlement of the foundations has occurred and movement is no longer on going. The front elevation was [**repointed**](https://newmans.com/) with a specialist lime mortar and the bricks refaced using a hard wearing rapid setting mortar. With the bricks refaced a[ **brick tint** ](https://newmans.com/services/Brick-Facade-Maintenance/brick-tinting-and-repairs)was applied ensuring the bricks new brick faces would go barely un-noticed. To prevent further spalling due to freeze thaw cycle Twistfix stormdry masonry protection cream was applied which provides a permanent barrier repelling water from the façade. Being one of the only structural repair contractors actually based in London and working on this type of property on a regular basis we were able to complete the contract in only 7 days with 2 of our teams carrying out the works.

[**Lintel Failure**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) often occurs after the replacement of windows especially original hardwood timber frames which are often load bearing and resist any movement to the lintel so if you are having replacement windows you should always ask the contractor to prop the lintel whilst removal is taking place and monitor the lintel for any cracking afterwards. A [**Structural Survey**](https://newmans.com/services/Property-Surveys/Structure-Only-Report) was carried out from our office in Bristol which services South Wales and it was obvious that the lintel had dropped slightly leaving a crack in the render. Using the [**Twistfix**](http://www.twistfix.co.uk/) masonry reinforcement system we were able to restore the structural integrity of the masonry by inserting [**helical lintel reinforcement**](https://newmans.com/case-studies/lintel-repair/) into the bed joints above the window. As well as masonry beams Twistfix patented 450mm vertical pinning ties were installed through the lintel pinning the brick arch lintel to sound masonry above resisting any further downward movement. With resin injection to the cracks and render repairs to the pebble dashing the repair provides a lasting solution that will go unnoticed combined with a 10 year guarantee relieving a very worried home owner.

The properties were constructed during the 1930’s and are typical construction for social housing built during that period with brick to brick construction tied using an iron fishtail [**cavity wall tie.**](https://newmans.com/services/building-and-structural-repairs/wall-tie-replacement) **[Wall Tie Failure](https://newmans.com/services/building-and-structural-repairs/wall-tie-replacement)** is a common structural defect to properties of this type but external bowing walls are not as common so a suitable solution from us was required. [**Wall Tie Replacemen**](https://newmans.com/services/building-and-structural-repairs/wall-tie-replacement)t was carried out isolating the existing ties across the ten properties using the Patented CD helical wall tie supplied to us by Twistfix of whom we are a proud registered contractor. The bowing external walls were restrained by installing Twistfix 6mm Helical rods within the external Bed Joint and drilled into the internal party walls and secured using Twistifx WHO-60 masonry reinforcement grout anchoring the L shaped rod into the masonry resisting any further outward movement. As well as crack stitches tying the cross walls to the external walls internal cracking was present and again Twistfix crack stitches were used in order to restrain further separation. Once Brick Repairs, Repointing, Rendering and Plastering had been carried out the repairs were left almost invisible providing a lasting solution to structural defects. Using the Twistfix Remedial system we were able to save the council vast amounts of money time and disruption.

Newman’s were asked to competitively tender for the concrete repair works to their building in Watford high street. **Concrete** had been witnessed falling off of the building posing a very high risk to the general public as the **spalling** extended across the 15 storey high tower block. **Carbonation** of the **concrete** had occurred due to the tower blocks location and low concrete cover. Our in house concrete repair team, all trained abseilers, carried out a survey to the tower block to determine the amount of repairs necessary and the depth of carbonation. Cover metre tests were also carried out and it was noted that cover of concrete to the reinforcing rods was as little as 10mm is some areas. In order to repair the **spalled concrete** our team of repairers cut out the concrete to locate low cover steel reinforcing that had suffered from carbonation attack. Initially carbonation of concrete hardens the concrete and increases its compressive strength but as the carbon penetrates further into the concrete a chemical reaction occurs which damages the passivating layer which protects the reinforcing from moisture, as this breaks down it allows moisture absorbed naturally by the porous concrete to corrode the steel causing expansion and spalling of the concrete. Carbonation is unstoppable especially in porous concrete and to steel reinforcing that has low concrete cover. The effect of carbonation can be devastating leading to total structural collapse if ignored for a long period of time. It is essential that concrete is sealed to resist the threat of carbon attack. In order to repair the spalled areas the concrete was hacked out to expose the corroded steel and the steel cleaned to SA 2 ½ it was then treated with Flexcrete steel reinforcing protector, the area of repair was then repaired with Flexcrete monolite concrete repair mortar. Newman’s are a specialist concrete repair contractor and have the capabilities to carry out concrete repairs to almost any structure suffering from concrete defects. **Newman’s can help to diagnose structural defects, cracking and movement by arranging a free Structural Survey, contact London and the south East’s leading structural repair specialists for Help, Advice and peace of mind Call 0333 444 0154 or Email info@newmans.com** --- ### [Bowing Walls London](https://newmans.com/case-studies/bowing-walls-london-2/) **Published:** August 24, 2016 **Author:** Jon Newman **Content:** ### Bowing Walls in London are relatively common structural defect that occurs to Victorian and Edwardian properties which make up much of London’s housing stock. Newman’s are often faced with this **structural issue** and have become highly experienced in rectifying this problem using non-disruptive modern methods of reinforcement supplied to us by manufacturer and supplier Twistfix. **[Bowing walls](https://newmans.com/services/building-and-structural-repairs/lateral-restraint)** and **lateral instability** usually occurs when the masonry panels, often solid walls, aren’t connected to the floor joists, ceiling joists and stair cases. Without this connection the brickwork can act freely and will move under altering structural loads, ground movement or high winds. It is essential for the stability of the structure that the building is tied into the brickwork in order to prevent cracking or even collapse of the structure by having this connection. Newman’s can design and implement suitable repair solutions to overcome this problem and provide lasting concealed repairs. This property in Central London’s Fitrovia, W1, which was once home of the famous writer George Bernard Shaw, was suffering from major lateral instability causing cracking at party wall junctions to the rear elevation of the building. As often with this type of property the narrow stair cases have many rooms leading off of landings at various levels and the 5 storey 13 inch solid brickwork was completely un-connected leaving bowing walls at floor joist level and outward leaning walls at 4th and 5th floor level. With the building being a listed structure it was essential that our design included a concealed solution that would provide adequate restraint to the masonry and again the **Twistfix** range of **[lateral restraint](https://newmans.com/services/building-and-structural-repairs/lateral-restraint)** solutions were key to the repairs schemes success. In order to tie the rear elevation to the flank elevation **[bed joint reinforcement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2)** was chased into the external rear corner at 450mm centres vertically up the entire height of the building, this was then drilled into the internal skin of brickwork where it was chased into the masonry and grout fixed creating an L shape tie which would resist further outward movement. Once repointed and plastered this permanent connection would be invisible to the eye. Cracking to junctions of stud walls were apparent and the **bowing** was more severe at this section which was in the middle of the rear elevation, with the plaster removed on one side of the stud wall we installed additional noggins between the studs to provide extra strength and installed **Twistfix [lateral restraint ties](https://newmans.com/services/building-and-structural-repairs/lateral-restraint)** at every 400mm centres the full height of the building. The ties are installed through the exterior of the brickwork and self-cut into the timber stud work once installed 10% of the ties were load tested achieving a minimum of 3 K/n’s pull out force. The connection is made with rapid set WHO-60 grout and once brick repairs were carried out the connection is invisible to the eye. As well as [**lateral restraint ties**](https://newmans.com/services/building-and-structural-repairs/lateral-restraint) into the stud walls, ties were required into the landing floors to prevent further bowing. Ties were installed every 400mm’s again and connected in the same manor. This method of repair provides a lasting permanent solution resisting further lateral movement. **Newman’s can help to diagnose structural defects, cracking and movement by arranging a free Structural Survey, contact London and the south East’s leading structural repair specialists for Help, Advice and peace of mind Call 0333 444 0154 or Email info@newmans.com** --- ### [Structural Repairs - London](https://newmans.com/case-studies/structural-repair-london/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s were once again called upon by a London council in order to provide a Structural Repair service in order to repair Cracking to a sheltered housing property for elderly residents. The tenant had discovered that cracking had occurred to the external brickwork whilst she was carrying out her spring gardening. The cracking hadn’t been there before the winter of which we had received record levels of rain. Our in house team carried out a soil investigation to determine the type of foundation and the soil of which the structure had been built off of and it was determined that minor subsidence had occurred as a result of the clay subsoil swelling and then shrinking causing the brickwork to crack. The cracking was monitored for a period of 6 months by our engineers and we could confirm that the movement had stopped and we could then design and implement a cost effective Structural Repair programme of works to restore the integrity of the masonry. In order to provide a lasting repair that would cause as little disruption to the elderly tenant our surveyors designed a specification that utilised the Twistfix bed joint reinforcement system to distribute structural loads across the masonry and resist further cracking. In this instance it was necessary to create load bearing beams within the brickwork and the Twistfix helical wires were installed in pairs to create ‘helibeams’ which in effect create lintels within the brickwork to reinforce the masonry and resist further cracking. The 2nd generation system supplied by Twistfix is the most innovative system available. The bars were wrapped around the bungalow ensuring the masonry would be able to resist further settlement and the works were covered by a 10 year insurance backed guarantee. Once the bed joint reinforcement had been installed and the slot re-pointed the works were almost invisible.

After an extensive survey of the property it was discovered that the cracking had occurred due to [lintel failure](http://newmanbuildingsolutionscom.createsend1.com/t/j-l-eirity-l-s/) above the window to the gable elevation as well as outward movement to the rear elevation. Whilst carrying out our free survey we found that the parapet wall had also failed allowing moisture to penetrate between the render and masonry causing it to become delaminated and unsafe. This is a very common defect with period properties but it should only be left to the specialists to propose and implement a suitable repair strategy. Using a combination of [bed joint reinforcement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2) and pinning ties we were able to create helical masonry beams within the masonry distributing structural loads to the gable elevation lintel. The rear elevation was repaired and restrained with a combination of [bed joint reinforcement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2) as well as [lateral restraint](https://newmans.com/services/building-and-structural-repairs/lateral-restraint) techniques tying the masonry to the floor joists without the requirement for pattress plates thus giving a hidden repair. Upon closer inspection to the parapet wall it was found that water was getting behind the render damaging the flank wall masonry as well as delaminating the render. The original parapet had previously been repaired poorly and it was decided Newman’s would have to remove 3 courses of masonry and the delaminated section of render in order to provide a lasting repair. Reclaimed bricks were used to rebuild the masonry with new lead work and render providing a permanent solution. --- ### [Walkway Repair With Minimum Disruption To Residents](https://newmans.com/case-studies/walkway-repair/) **Published:** April 4, 2017 **Author:** Jon Newman **Content:** Newman’ns were contacted by Arun Council who were looking for a contractor to advise them of the best and most practical way to repair the issues that they had with damaged asphalt walkways on three blocks of flats. Newman’s had several meetings with the client both on site and at their offices. Examples of previous walkway repair projects were shown along with samples of how our [balcony and walkway repair](https://newmans.com/services/balcony-and-walkway-repairs/) system works. **The Problem** The asphalt walkways had cracked and deteriorated in such a way that water was penetrating the coating and causing the steelwork inside the concrete to corrode. The concrete was then spalling due to the steel work expanding. Also, at the rear of the properties, lintel failure had occurred and cracks were enabling water penetration into the flats. **The Solution** The solution was to install a fast cure, waterproof walkway, the Vulkem Quick Balcony System. This system was recommended because as well as being extremely effective, its fast cure time of approximately one hour, keeps disruption to residents down to an absolute minimum. The Vulkem system was installed to all three decks. The cracks in the balcony floor were raked out and injected and the new membrane installed over the top of the existing finish. This has the added benefit that the tenants can still use the walk ways to enter their properties. Once the walkways were made waterproof the concrete repairs were completed using [Steadfast Jahn M90 Concrete Repair Mortar](http://steadfastspl.com/jahn-repair-mortars/jahn-m90-concrete-repair-mortar/). An anti-carbonation coating was then installed over the top to complete the aesthetics of the underside of the balcony. [Lintel repair](https://newmans.com/services/building-structural-repairs/lintel-repair/) was completed with the installation of Steadfast Thor Helical masonry beams above the rear lintels. These distributed the loads and all cracks were raked out and injected with a colour matched thixotropic grout. All external surfaces were cleaned using the DOFF superheated steam system before fully painting all sections in the councils specified RAL colours to allow a full restoration of the surrounding areas and bin stores. --- ### [Wall Tie Replacement- Guildford](https://newmans.com/case-studies/wall-tie-replacement-guildford/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Working closely with our client, a national loss adjusting firm, Newman’s were asked to carry out a structural survey and design a structural repair specification to stabilise the failed masonry of this single storey bungalow in Guildford. Upon completion of the structural survey it was discovered that the existing wall ties were inadequate and had also failed. Various areas of pointing were also lose and failing requiring a specialist stabilisation programme. Newman’s, being approved Twistfix contractors, designed a wall tie replacement specification that would be guaranteed for 25 years. The Twistfix 9mm Helical CD wall tie was used at 900mm x 450mm centres providing 2.5 wall ties per metre square. The ties were installed using a dry fix method and were installed through a 6mm pilot hole. Pull out tests were carried out at random intervals and the lowest pull-out achieved was 1.2n/m’s. Using the dry fix method provides a fast and effective wall tie replacement scheme providing adequate structural integrity and restraint against further movement. Areas requiring repointing were raked out using conventional grinders with dust extraction to a depth of 35mm and the masonry was stabilised using thixotropic cementitous grout injection leaving a 10mm recess to repoint providing a hidden structural repair. All works were carried out to a high standard with the wall tie replacement scheme being guaranteed for 25 years providing the only insurance backed guarantee within the industry.

This week our team of concrete repair specialists have been repairing the underside of a concrete slab that is home to some large machinery on the first floor which had suffered from extensive damage causing large sections of concrete failure. The slab is 200mm thick with reinforcing rods at every 60mm which have in areas corroded extensively causing the concrete to spall. As well as corrosion to the reinforcing rods the machinery above was causing heavy vibration caused by un-level slab which required levelling. The reinforcing rods were treated using Flexcrete Steel reinforcement protector which prevents further corrosion of the reinforcing bar. Using handheld hammer drills spalled concrete was removed and Flexcrete Monomix HD was applied by hand. Specifying and applying the correct repair mortar is essential to provide a lasting repair and only a specialist contractor should be selected in order to carry out concrete repair. Flexcrete Monomix HD repair mortar is one of the best on the market and Newman’s are able to utilise all of their specialist products in order to carry out repairs in almost any situation of concrete failure. If you are an engineer or specifier of concrete repair products we would highly recommend the Flexcrete System.**[www.flexcrete.com](http://www.flexcrete.com/)** **[If you are looking for further information on concrete repairs visit our informative concrete repair section here](https://newmans.com/services/Concrete-Repair-Solutions)** --- ### [Bowing and Cracking Walls Hertfordshire](https://newmans.com/case-studies/bowing-and-cracking-hertfordshire/) **Published:** August 24, 2016 **Author:** Jon Newman **Content:** Newman’s were asked to carry out a survey to a Victorian end terrace property in Bishops Stortford, Hertfordshire, by a private landlord who was extremely concerned by bowing and cracking walls in this 1830’s Victorian built cottage. Upon inspection of the property the bowing was found to be significant and that existing lateral restraint ties installed in the 1950’s had failed due to corrosion. There was cracking at the junction of the party wall with the main structure, combined with gaps appearing at ceiling level and at first floor level. Cracking to the front of the property was also evident and the cause of this which was [lintel failure](https://newmans.com/case-studies/lintel-repair/), a common defect to properties of this age and construction. The solutions to the defects was to install [masonry beams](https://newmans.com/services/building-structural-repairs/bed-joint-reinforcement/) drilled 1000mm and resin fixed into the party wall all the way around the gable wall and resin fixed into the rear wall a further 1000mm. This would tie the midriff of the property together and distribute the structural loads across the worst areas of bowing to sound masonry. The lintel was repaired using 450mm 9mm stainless steel Twistfix pinning ties with each bed joint within the lintel raked out and grout injected stabilising the lintel. The joists were inspected and found to be sound with no signs of defect so 15 no 1.5m long Twistfix [lateral restraint](https://newmans.com/services/building-structural-repairs/lateral-restraint/) ties would be the effective solution to provide a permanent restraint to the front and gable elevations. The party wall was tied to the external front wall with 2m long crack stitches chased from the party wall and drilled through the external front wall providing an L shaped grouted tie. The ground floor party wall was tied using 1m long 9mm grout ties. Once the grout had set pull out tests were carried out to the grout ties and the lowest pull out reading was 2.5 kn’s. With all areas re-pointed and plastering carried out the repairs provide an almost invisible repair solution alleviating the need for costly remove and rebuild techniques and provide a permanent solutions covered by a 10 year insurance backed guarantee.

A survey was carried out indicating that the extent of the lintel failure was severe and required stabilisation by the introduction of bed joint reinforcement combined with resin injection to create load bearing beams within the masonry and stabilise the lintels. Two masonry beams were installed between each window opening to alleviate the structural loads from the failed brick arches and restoring the aesthetics. The project was completed on time and within the agreed budget providing a guaranteed permanent repair.

To restore the structural integrity of the masonry Newman’s designed a specification that would allow the installation to be carried out in a day but also restore the integrity. Deep masonry beams were installed above the lintel distributing structural loads and the brick lintel was propped back into position and resin injected creating a load bearing high strength lintel whilst restoring the original aesthetics of the building. As well as lintel failure a 3mm crack was stitched using 1.2m single crack stitching rods where cracking had occurred caused by a change in loadings where lintel failure had occurred.

Along with the consultants at MACE group and the principal contractor ASHE construction, we carried out a [structural survey](https://newmans.com/services/property-surveys/structure-only-report/) and proposed a design scheme. ASHE were carrying out the refurbishment of the library and whilst removal of the original windows and installing aluminium frames it was found that there was major cracking and rotation of the masonry panels leaving them unsecured posing a severe health and safety risk. Newman’s were instructed to diagnose the cause of the cracking and the rotation to the masonry panels. Our surveyors discovered that the masonry had sagged and rotated outwards as the original construction was defective. The brick panels were built on a concrete frame and usually up to one third of the brick work over hangs the concrete toe. In this case it was discovered the concrete had become defective and the brick work was sat just over halfway on the concrete toe allowing the masonry to lean outwards and sag. As well as the rotation the brick slips had become loose and some areas of brick work had actually collapsed. This defect was discovered above every opening and window span to the library. Our scheme had to restore the structural integrity of the masonry and provide a permanent solution that would be insured by a genuine insurance backed guarantee in the event of a failure for peace of mind for the client. Being approved Twistfix contractors and members of IGL we were able to provide such a scheme that was guaranteed for 20 years. With deep helical beams installed into the masonry panels at 450mm centres the structural loads and sagging across the 25m span was spread throughout the panel preventing any further sagging. 9mm stainless steel CD DriveFix ties were selected as the installation process is rapid with just a 7mm pilot hole required and the tie becoming load bearing as soon as they are installed so there wasn’t any setting times preventing the structural integrity being restored. Cracks were raked out to a depth of 45mm and injected with Twistfix high strength rapid setting resin providing a secure bond between the separated masonry. The underside of the concrete toe, that bears the full load of the masonry panels, was found to be suffering from concrete failure which was caused by oxidisation of the reinforcing rods. This was due to the original build as well, with the reinforcing being too close to the concrete allowing moisture penetration. This was repaired by Newman’s using a zincrich primer sealing the exposed steal preventing further corrosion. We then applied a heavy duty repair mortar reinstating the strength of the concrete. Brick slips were fixed back to the concrete toe using Twistfix cementitious grout and a 9mm pinning tie ensuring they will not be able to come loose or drop in the future.

We were contacted by an elderly couple who had recently had their timber windows and doors replaced with uPVC double glazing but, as is often the case upon removal of uPVC windows, the lintels fail causing cracking and sagging leaving the masonry above unstable. Newman’s are experts in the field of [lintel repair](https://newmans.com/services/building-and-structural-repairs/lintel-repair/) and are able to specify insurance backed repair solutions to stabilise masonry across London and the South East using the Twistfix system. Lintel Failure had caused the soldier course lintel to the rear of this 1950’s property to sag bowing the uPVC frame due to its non-load bearing capabilities that the original hardwood French door incorporated. The solution we provided was to install masonry beams, which are twin rods within the bed joint acting in tension and compression and incorporated with Twistfix Cementitious grout distributing structural loads across the masonry. Stainless steel 9mm Twistfix pinning ties were inserted vertically 450mm through the brickwork in the soldier course lintel ensuring there would be no further downward movement or rotation. The entire panel was then raked out and injected with the Twistfix grout ensuring the whole panel acted as one restoring the structural integrity. The panel was then repointed with matching mortar from parex . The contract was completed with-in two days, at a fraction of the cost of traditional remove and rebuild techniques originally proposed.

In order to assess the cause of cracking to the building a visual inspection of the masonry was carried out as well as utilising our in house soil investigation and drainage survey team to assess all causes to the cracking. Our surveyor carried out an extensive investigative survey and discovered the cause of cracking was due to subsidence caused by vibration from the high speed rail track situated less than 20m’s from the property. The soil investigation discovered that the property was built on firm to stiff clay which is common across the South East of England but the foundations, which we would usually assume as being a concrete slab was actually just a non reinforced ring beam built on made up ground. Our drainage survey concluded that no drains were defective. In order to repair the cracked masonry a piling scheme would need to be implemented combined with a Twistfix helical solution to repair the cracked masonry. Over 300 metres of helical bar was installed into the bed joints to reinforce and tie the cracked masonry creating load bearing [masonry beams](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-crack-repair/) within the bed joint to distribute the structural loads in conjunction with BRE standards. When our engineers devised the piling scheme we had to ensure that minimum disruption to the elderly tenants as their properties were to remain lived in whilst works were being carried out. The solution was to install 300mm augured piles 10 metres into bedrock with 10 pile caps in total and 2 piles within each pile cap one acting on the compressive forces and one on the tensile loads to ensure that all load’s would be restrained. [Brick repairs](https://newmans.com/services/total-wall-care/brick-tinting/) were carried out to the front of the property for aesthetic reasons in order to preserve the building as the brick work had come out of line due to subsidence causing the building to rotate. The structural repairs and piling works took only 10 days to complete and the contract was delivered on time and well within budget.

We were asked to carry out a survey to the retaining wall which was showing minor signs of outward movement which had caused some areas of cracking. As well as cracking to the retaining wall minor **[lintel failure](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure)** had occurred to the rear of the property which went unnoticed by two other contractors. Using the BRE guide provided to us as a registered contractor for [**Twistfix**](http://www.twistfix.co.uk/) we were able to design and suitable programme of repairs and an engineered solution that would provide a permanent repair. Cracking to retaining walls is a serious issue and the owner of the wall is legally responsible to ensure that their wall is safe and should any persons be injured due to a fault in the wall then the owner will be responsible. **[Visit one of our blogs here for your legal duty and responsibility.](https://newmans.com/retaining-walls-their-failure-and-your-legal-risk/)** The cracking to the retaining wall on the car park side was repaired with the installation of [**Bed Joint Reinforcemen**t](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2) creating masonry beams using 9mm Twistfix helical bar encompassed in Twistfix WHO-60 masonry reinforcement grout which would resist any further separation. With the cracks raked out and injected with Twistfix Epoxy Acrylate resin this method of repair ensures stability. On the clients side of the wall crack stitches were installed in various area’s were separation and minor cracking was present which if left unrepaired could lead to serious structural defects. The minor lintel failure to the rear elevation was repaired again by using Twistfix **[Bed Joint Reinforcement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2)** to create masonry beams distributing the structural loads. Six bricks had to be replaced due to the cracks being the whole way through the brick. Various areas of repointing was also carried out whilst we were on site as well with mortar matching the existing. The repairs were guaranteed for 10 years with an insurance backed guarantee which can be extended after the ten year period once inspected. The client was exceptionally happy with the level of service they received and recommended us to a family member. --- ### [Concrete Repairs Walkway Coating- Dorset](https://newmans.com/case-studies/concrete-repairs-walkway-coating-dorset/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s have been awarded six phases of **[Concrete Repairs](https://newmans.com/)** and walkway coating to blocks of residential holiday lets in Westbay, Dorset. The contract will last approximately 5 months in total including the application of anti-carbonation coatings and sacrificial anodes. The concrete to the first phase of repairs to the back of Heron Court had caused increasing concern to the residents due to parts of the balcony falling off luckily not causing any harm to any persons below. The asphalt coating on top of the balcony had become worn over time and had cracked in places which allowed moisture to penetrate into the concrete and the freeze thaw cycle could begin causing expansion in the concrete causing cracks and fractures to occur. With the property being on the sea front the moisture had a high salt content causing the steel reinforcing to oxidise and corrode which again caused the concrete to crack and delaminate. Being on the sea front alkali attack had also occurred causing failure in the concrete. The corroded steels were located using metal detectors and the failed concrete hacked off to expose the reinforcing bars so that the rust could be removed using mechanical abrasion to take the steel back to sound metal. Newman’s use the Flexcrete range of concrete repair mortars and concrete protection products as we believe they are by far the most superior range of products on the market. To repair the underside of the balcony channels were cut out and Flexcrete Monolite hand applied Concrete Repair mortar was troweled in to give a lasting repair that is extremely strong. 2mm fairing coats were then applied to give a smooth plaster like finish. As well as the application of new **[Concrete Repair](https://newmans.com/)** mortar a corrosion inhibitor was used to protect all of the steel reinforcing rods. The corrosion inhibitor is spray applied to all of the concrete and seeps through the concrete and reacts with the oxygen and binds to the steel to provide a complete coating which will prevent further oxidisation. Being the only approved contractor in the South West of England to design and install RPM-Belguims unique walkway coating we were asked to carry out some test samples to show the client what the balcony could potentially look like and once the samples were applied we were quickly given the order to coat the entire walkway. The unique coating provides a 100% waterproof coating without the requirement for removing the existing asphalt. In order to apply the coating the asphalt had to be repaired using RPM-Belgium’s Ready Rep repair mortar which rapidly sets forming a water tight seal which is hard wearing and once applied the coating can be installed. The coating differs from all other products available to the UK market as it can be applied in almost all weather conditions and once laid will be walkable on within one hour of application. The coating is 100% waterproof and non-slip and with the installation time being so very short it is the perfect solutions for repairing and providing an aesthetically pleasing finish to walkways and balconies. Once the balcony had all the Concrete Repairs completed and the Walkway Coating applied Newman’s then applied Flexcrete’s series 2 ultra Anti Carbonation coating which will protect the concrete from a range of defects and also allows moisture to escape through the coating that will prevent the paint from bubbling and flaking which is a common problem. The client was so happy with the high quality workmanship that were asked to provide a specification and detailed report to the entire estate which is made up of 6 blocks of residential holiday lets. The second of six phases is now underway and the schedule will last for approximately 5 months with a contract value of £300k. --- ### [Masonry Beaming Middlesex](https://newmans.com/case-studies/masonry-beaming-middlesex/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s have gained a superior reputation with many surveyors and structural engineers across London and the South East. We were recommended by a building surveyor for whom we do much repeat business and were asked to give advice and design a repair scheme for this large manor house in Middlesex. A **[Structural Survey](https://newmans.com/services/Property-Surveys/Structure-Only-Report)** was carried out by one of our permanent London based surveyors from our head office in Hammersmith and Lintel failure was identified as the cause of cracking to the brickwork and render to the front elevation and west wing. Being a [**Twistfix approved contractor**](http://www.twistfix.co.uk/) we have access to the only helical repair system that has undergone BRE testing which enables us to ensure that the repair system designed by ourselves providing an engineered solution. Using the Twistfix **[Bed Joint Reinforcement](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2)** we were able to create lintels within the existing masonry by inserting 2 No helical rods encompassed in masonry reinforcement grout installed in pairs above the failed lintel ensuring the downward forces which caused the original lintel to fail are now distributed across the bar into sound masonry which prevents further structural damage. Areas of separation were also repaired using Twistfix helical bar by installing masonry beaming across the crack which effectively stitches the crack and prevents further separation. Original quotations provided to the client lead the client to believe the only method for repair was to remove and rebuild, which in some instances is the only option, in this scenario it was far less invasive and time consuming to use a modern method of repair. The **[Lintel Reinforcement](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure)** scheme was guaranteed with one of the only genuine insurance backed guarantee for structural repair works by Insured Guarantees Limited who Newman’s are approved by. --- ### [Structural Repairs External Refurbishment London](https://newmans.com/case-studies/structural-repairs-external-refurbishment-london/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s were asked to visit a property in East London in order to assess and install and remedial solution to rectify extensive and live cracks to the bay window which was pulling outwards from the main structure due to a lack of lateral restraint. As well as movement to the bay window there was also [Lintel Failure](https://newmans.com/case-studies/lintel-repair/) which is a common structural defect for properties of this age and type of construction. Twistfix [Bed Joint Reinforcement](https://newmans.com/services/building-structural-repairs/bed-joint-reinforcement/) was specified in order to restore the structural integrity of the Failed Lintels as well as tying the bay window back into the main structure. Bed Joint reinforcement was used to create masonry beams by chasing out the mortar to a suitable depth and inserting 2 helical rods encompassed in specially designed Twistfix WHO-60 grout. This distributes structural loads as well as providing a fixed connection. As well as Structural Repairs we were asked to carry out a full External Refurbishment including replacing defective lead work, removing and replacing rotten timber fascia and soffit boards, new gutters and down pipes, installing tile vents and sealing all windows. As part of the external refurbishment we also carried out full rendering of the external front elevation using Weber polymer-modified cement based render which we could apply a 10 year guarantee to. The repairs were carried out on time and within budget and left for redecoration by the clients own painter. --- ### [Structural Repair West London](https://newmans.com/case-studies/structural-repair-west-london/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s were asked to competitively tender to carry out the design and installation of bed joint reinforcement and parapet wall stabilisation to a community centre in West London which had suffered multiple areas of vertical and horizontal cracking. Our surveyors carried out a detailed Structural Survey to diagnose the cause of the cracking and it was found that the building was built on made up ground and had suffered from settlement of the foundations. Soil investigations were carried out by our survey division to confirm the makeup of the ground and monitoring pins were installed to monitor the movement. After six months of crack monitoring there was very little movement and a repair solutions was designed. Twistfix [**Bed Joint Reinforcement**](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2) was specified in order to tie the cracked masonry together and distribute the structural loads. With the masonry beams wrapped around the entire building the masonry acted as one reinforced panel which resisted structural movement and further settlement. The parapet wall was found to be separating from the main structure leaving horizontal cracks at the fracture and some areas of the parapet becoming unstable. Twistfix 1200mm grout ties were installed vertically through the coping stone into the parapet wall and then into the main structure creating a grouted column reconnecting the parapet and the main structure. Areas of de-bonded render were removed and hair line cracks were raked out and injected with resin prior to re-rendering. The works were completed within two weeks during the school holidays to minimise disruption to the community centre and the works were completed well within the budget. Once the Twistfix helical system was installed the structural movement was restrained and a 10 year IGL **insurance backed guarantee** was issued against further cracking. --- ### [Masonry Repairs London](https://newmans.com/case-studies/masonry-repairs-london/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s were once again called upon by a private residential home owner who has recently purchased and in the process of renovation this 3 storey Victorian property requiring Masonry Repairs. Our surveyors carried out a **[Structural Survey](https://newmans.com/services/Property-Surveys)** which included non-intrusive visual inspection and site investigations to determine the cause of the movement and cracking. It was found that there was a lack of **[Lateral Restraint](https://newmans.com/services/building-and-structural-repairs/lateral-restraint)** the two storey bay windows to the front and rear of the property which was causing it to rotate outwards. As well as Outward Movement it as apparent that the lintels had failed which is a common defect to this type of property. **Masonry Repair** scheme was designed incorporating the **[Twistfix](http://www.twistfix.co.uk/)** system which included the installation of 6mm helical bar encompassed within WHO-60 grout creating masonry beams within the bed joint which were drilled into the internal masonry tying the bay into the main supporting walls resisting further outward movement. Masonry Beams also distribute loads across the structure and are used to repair **[Lintel Failure](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure)**. Areas of **[repointing](https://newmans.com/)** were also undertaken due to weathering of the bed joints which caused much of the mortar to become lose or missing. A traditional lime mortar was used to match the existing mortar. The repair was guaranteed for 10 years against failure by an insurance backed guarantee. --- ### [Lintel Failure Reinforced London](https://newmans.com/case-studies/lintel-failure-reinforced-london/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s carried out a [Structural Survey](https://newmans.com/services/Property-Surveys/Structure-Only-Report) to the external façade of this imposing six storey building constructed in an 18th century garden square in Marylebone in the City of Westminster. Built in approximately 1776 the building has stood the test of time and it was to no surprise that the external façade had suffered from various areas of cracking and structural defects requiring urgent attention. The premises had become headquarters to a large law firm and whilst carrying areas of external decoration Newman’s were called upon to diagnose, design and implement a [**Structural Repair**](https://newmans.com/services/building-and-structural-repairs) solution the reinforce the brickwork that had suffered from **Stepped Diagonal Cracking** caused by extensive [**Lintel Failure**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure). [**Lintel Failure**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) is a common problem to buildings built in the Georgian era due to the flat gauged arch **Lintels** losing their camber causing them to sag due to increased loads imposed by the supported masonry above requiring the need for repair or [**Bed Joint Reinforcement**](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2). Newman’s specialise in **Masonry Reinforcement and Repair** particularly in the field of [**Lintel Reinforcement**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) using [**Twistfix’s**](http://www.twistfix.co.uk/)Helical Wires we can create new load bearing beams within the brickwork, commonly known as [**Bed Joint Reinforcement**](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2), which utilises the **2nd generation ‘Helibeam’ system** manufactured and engineered by **Thor Helical**. With the introduction of Helical Wires installed in pairs above the lintels resist the compressive and tensile forces imposed on the masonry by the [**Lintel Failure**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) as the Helical Wires are installed in pairs within the bed joint encompassed in grout to create the load bearing beams. The existing cracks are then cut out and also injected with grout to bond the separated masonry. Over 100 square metres of [**Re-pointing**](https://newmans.com/) was found to have been effected compromising the structural integrity of the masonry which would lead to problems with penetrating damp as well as structural issues caused by the freeze thaw cycle. Much of the brickwork had become unstable requiring immediate action and again [**Twistfix’s**](http://www.twistfix.co.uk/) range of products excelled and WHO-60 masonry repair grout was used to stabilise the live brickwork prior to re-pointing. With the brickwork above the [**Failed Lintels**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) reinforced and the cracks bonded together the vast areas of **[Re-pointing](https://newmans.com/)** was carried out using traditional lime mortars which matched the existing mortar almost perfectly providing a rapid [**Lintel Repair**](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) which was almost invisible to the eye. Over 400 metres of Helical Wire was installed to reinforce the structure, using the innovative **Helibeam system** we were able to save our client thousands of pounds as well as provide a non-disruptive solution and the works were completed within two weeks. --- ### [Bowing Walls London](https://newmans.com/case-studies/bowing-walls-london/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s were called upon by a property developer who had recently purchased a Victorian property in order to renovate and let to tenants as soon as possible. The property, in serious need of Structural Repairs, based in south west London was close to our head office in Hammersmith, West London and due to the urgency of the works a surveyor was able to attend site within 24 hours. A visual survey was carried out and it was discovered that there was a lack of lateral restraint causing outward movement resulting in bowing walls. As well as outward movement there had been some rotation of the brickwork to the rear corner building. The client was also removing the entire ground floor brickwork to allow the installation of new bi-fold doors and the masonry above was in a state of disrepair. Our survey devised a structural repair scheme that would restrain the bowing walls by tying the masonry into the floor joists using [lateral restraint](https://newmans.com/services/building-structural-repairs/lateral-restraint/) ties. Twistfix Masonry beams are always installed above and below the lateral restraint ties creating a restraint zone which allows the ties to all act as one. The masonry was also tied into the first floor partition walls using Twistfix Helical bar ensuring there would be no further outward movement. [Crack stitches](https://newmans.com/services/building-structural-repairs/bed-joint-reinforcement/) were installed to the rear corner where rotation had occurred creating a grouted L shape tie which would prevent any further rotation. With the masonry on the rear elevation being removed masonry beams were installed to reinforce the bed joints distributing structural loads. Although the brickwork appeared to be of 9” solid wall construction it was found that in fact the masonry was a cavity wall with slight rubble fill so Twistfix [wall ties](https://newmans.com/services/building-structural-repairs/wall-tie-replacement/) were installed creating a structurally sound solution. The works were carried out in four days in order to prevent any hold up for other tradesmen on site and the works were completed on time and within budget. If your property is suffering from cracked masonry, outward movement, bowing walls etc and is in need of a structural survey then be sure to contact your local Newman’s office. --- ### [Lintel Repair South East London](https://newmans.com/case-studies/lintel-repair-south-east-london/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** ## Lintel Repair, South East London. Newman’s were contacted by a local structural engineer who had been monitoring the cracking and progressive lintel failure to this three storey rear outrigger. The stone lintels on all three storeys had failed causing them to drop and lose all structural integrity and allowed the masonry above to drop showing 1-4mm staggered cracking; a common defect to these Victorian built rear additions. Traditional methods of repair such as remove and replace are not necessary with modern methods of [lintel repair](https://newmans.com/services/building-structural-repairs/lintel-repair/) which utilising the helical bar system. We create deep masonry beams within the bed joint distributing structural loads combined with resin injection systems reinstating the structural integrity of the lintels. Using Newman’s modern methods of building repair we can save days in labour time which in turn saves hundreds of pounds. --- ### [Structural Repairs - Islington](https://newmans.com/case-studies/structural-repairs-islington/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s specialist services were called upon to design and rectify structural defects that had caused some severe cracking to this Victorian built three storey house in Islington, North London. The structural defects were assessed by one of our experienced surveyors who carried out a visual survey of the property and found that there had been extensive lintel failure causing the masonry above it to sag and drop leaving the masonry unstable. The two storey bay window to the front elevation had also suffered from major outward movement caused by movement to the foundation it had been built on. This defect is a common defect to this type of property due to the foundation often being inadequate. In this instance restraint to the movement was rectified without the need for piling or underpinning. With the use of Twistfix helical bar we were able to create masonry beams within the brickwork which enables us to distribute structural loads across the structure preventing further cracking and remove the stress from the existing brick arch lintels. As well as reinstatement of the structural integrity helical bar can also be used in order to tie brickwork that is suffering from outward movement by tying the brickwork of the bay window into the main structure which resists further outward movement. Areas of the brick work were found to be severely unstable and Twistfix Thixotropic grout was injected into the masonry in order to stabilise it before repointing was carried out to provide a permanent repair. The rendered areas of the masonry was repaired as it was found to have localised areas of de-bonding and cracking and once redecorated the repairs were almost invisible. --- ### [The Old Dairy House Refurbishment](https://newmans.com/case-studies/the-old-dairy-house-refurbishment/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s were contacted by the owners of this 16th century farmhouse as they needed advice and costing for the refurbishment of the external fabric of the building as well as improving the security and kerb appeal. The external rubble filled walls were found to be suffering from delamination so Twistfix delamination grout ties were installed at 450mm x 450mm centres in addition to delamination ties the corners of the property were reinforced and stabilised using 2m long [cementitious sock anchors](https://newmans.com/services/building-structural-repairs/cementitious-sock-anchors/) installed at 600mm staggered centres cross pinning the walls. Deep bed repointing to various areas was also required using a specialist lime mortar. The main entrance of the property was made secure by constructing two 6ft high solid stone walls with 10ft x 6ft hardwood electric gates and new close board fencing. --- ### [Concrete Repairs North London](https://newmans.com/case-studies/concrete-repairs-north-london/) **Published:** August 24, 2016 **Author:** Jon Newman **Content:** Concrete Repairs North London. Newman’s were called upon to provide their unique services to a commercial client to undertake an extensive survey to a four storey office block that was under refurbishment. A Concrete Repair Survey was undertaken by our surveyors who found extensive defects including cancer of the concrete, oxidised and corroded reinforcing bar, defective supporting beams and pillars due to poor construction and hairline cracking. We provided the client with a detailed CAD specification highlighting the extent of the concrete failure and necessary structural repairs. Our trained technicians carried out the concrete repairs using various methods of trowel applied repair mortars and resins to the defective areas that included the floors walls and ceilings. Newman’s specialise in the use of Sika, Fosroc and Flexcrete products restoring the structural integrity of the concrete. The project was completed on time and within the agreed budget providing a guaranteed permanent repair. --- ### [Subsidence Repairs Oxford](https://newmans.com/case-studies/subsidence-repairs-oxford/) **Published:** August 24, 2016 **Author:** Jon Newman **Content:** Newman’s were awarded a contract by Oxford City Council, to design and install a repair specification to a 1950’s semi detached house that had suffered subsidence caused by damage to the foundations following tree root infestation. The tree was removed by one of our specialist sub contractors to prevent further subsidence. Our scheme comprised of Thor Heical ‘Screwdown’ Shire piles in conjunction with bed joint reinforcement. After an extensive survey and a soil investigation our engineers designed a piling scheme that would restrain further downward movement. 15 no shire piles were installed along the flank and the rear elevation at a depth of 4.8m’s into the clay soil to prevent further downward movement combined with deep masonry beams to the superstructure distributing structural loads. Internally areas of crack stitching was carried out along with masonry beams to stitch separated masonry and distribute structural loads. We carried out internal and external decoration and completed the repairs to a high standard on time and within budget, leading to repeat business. --- ### [Brick Repairs and Tinting North London](https://newmans.com/case-studies/brick-repairs-and-tinting-north-london/) **Published:** August 24, 2016 **Author:** Jon Newman **Content:** Newman’s were contacted by a building contractor who were at the final stages of a 12 month refurbishment to a six storey office block near the Angel in North London. Upon removal of tube and clip scaffolding there had been substantial damage to the brick work with the removal of the scaffold ties casing the face of the brick to shatter and crack leaving visible as well as structural damage. We were required to offer a repair strategy that would restore the structural integrity of the brick and reinstating the original aesthetics of the brick. Using an Acrylate resin the void in the brick formed by the drilling of the scaffold tie was filled offering a guaranteed solution to filling the void offering very high compressive and tensile strength. The face of the brick was repaired using Fosroc high strength concrete repair mortar and then tinted using specialist brick tinting techniques, offering a permanent repair. Specialist access equipment was used to carry out the repairs with access being gained from a cradle and cherry picker operated by our trained staff. We are increasingly being asked to carry out repairs of this nature for many refurbishment and new build contracts and if we can assist please do not hesitate to contact us.

It was discovered that extensive cracking had occured to the lintel above the ground floor entrance and that the first floor lintel above the window opening had suffered from extensive settlement. There was also a severe deep crack to the lintel on the rear elevation. We designed a repair scheme that would restore the structural integrity of the lintels and allow the safe installation of the external wall insulation. Deep masonry beams were installed by means of bed joint reinforcement above the ground floor opening with six vertical pinning ties installed, the separated head stone was then resin injected, restoring structural integrity of the masonry. The First floor window opening had dropped considerably, so our technicians propped the lintel back into position and chemically bonded the lintel to sound masonry. Once the chemical bond had set the lintel was cross pinned using grout ties into sound masonry and bed joint reinforcing was installed. The rear elevation lintel was repaired in exactly the same manner restroing structural stability and integrity.

Once on site it was deemed that the structure was unsafe and that the first floor required adequate supports to prevent collapse. We designed a scheme that would fully restore the structural integrity of the the masonry. Deep [helical masonry beams](https://newmans.com/services/building-structural-repairs/lintel-repair/) were installed above the ground floor window opening to distribute structural loads to allow the safe removal of the propping, damaged window and masonry. Once the masonry beams had reached their full load bearing capacity the window and stone surround was removed along with the damaged masonry. Our team of technicians rebuilt the damaged masonry and installed new energy efficient double glazing as well as uPVC window surround. Internally the damaged area was dry lined, plastered and redecorated. New laminate flooring was laid and the room restored to a superior standard. --- ### [Structural Repairs North London](https://newmans.com/case-studies/structural-repairs-north-london/) **Published:** August 24, 2016 **Author:** Jon Newman **Content:** Newman’s continues to build on its reputation for quality modern day methods of building and structural repairs leading to regular repeat business with many clients. We were contacted by a large consulting engineering company to carry out specialist remedial works for one of their most prestigious long standing clients. The property in question, a branch of Tesco’s, had suffered from a partial collapse of masonry. It was discovered that the cavity wall had been constructed with inadequate [wall ties](https://newmans.com/services/building-structural-repairs/wall-tie-replacement/), [movement joints](https://newmans.com/services/building-structural-repairs/movement-joints/) and wind posts. Much of the internal masonry was also found to be loose on the top two courses of block work. The devised scheme would restore the structural integrity of the masonry providing a fast and effective, non-disruptive solution required by the client. The Internal block work that had collapsed was rebuilt and reconnected to the external leaf of masonry using Twistfix Stainless Steel Wall ties at 450mm x 450mm centres along with all elevations. Movement joints were cut into the external leaf of masonry allowing the structure to move slightly and allow for any thermal movement or rotation. Specialist wind posts were fabricated and installed to offer additional strength and support against the high wind loads. The loose block work was restrained using specialist head restraint ties as well as an additional wall tie into the outer leaf of masonry. All works were completed on time and to high standard within budget. --- ### [Bay Window Restraint North West London](https://newmans.com/case-studies/bay-window-restraint-north-west-london/) **Published:** August 24, 2016 **Author:** Jon Newman **Content:** Newman’s were contact by a domestic private home owner who had noticed cracking had occured interanally and externally around the bay window, and were becoming very worried about the cause of the cracking. MD Steve Newman booked in a survey for the following day ensuring a quick repsonse and a repair specification with detailed method statement and quotation was proposed the same day. The bay window was moving outwards due to inadequate tying in of the masonry to the bay window, with no restraint being offered at the floor joist. The repair specifcation comprised of helical [bed joint reinforcement](https://newmans.com/services/building-structural-repairs/bed-joint-reinforcement/) to create deep masonry beams and tying the bay back into to the main structure with the bars being being returned to the internal front wall to provide adequate restraint. As well as local render repairs and decorating the works were completed within 4 days offering a hidden permanant bay window restraint that was guaranteed against failure for 10 years.

Our free structural survey identified a mild bulge in the thirteen inch solid wall as well as areas of cracking, outward movement and minor lintel defects. To restore the structural integrity of the masonry, bed joint reinforcement was used to create masonry beams above the right hand side window where a lintel defect was noted. Masonry beams were also installed above the courtyard opening where bulging had occurred. 2m Crack stitches were also used to tie the right hand corner of the building where bulging was apparent. Delamination ties were used to tie the bulging area at 750mm x 450mm centres combined with 2m lateral restraint ties stopping any further outward movement. The structural repair works were completed within two days and the making good was carried out by the construction company.

We carried out an extensive survey of the bay window and the front elevation and it was apparent that there had been [brick arch lintel failure](https://newmans.com/services/building-and-structural-repairs/Lintel-Failure) and outward movement requiring [lateral restraint.](https://newmans.com/services/building-and-structural-repairs/lateral-restraint) With the introduction of the [Twistfix ](http://www.twistfix.co.uk/)heliforce system, we were able to restore the structural integrity of the masonry. Twin 6mm helical rods were inserted into the bed joint crating masonry beams tying the bay window back to the main structure and distributing structural loads. Twistfix pinning ties were inserted vertically through the lintel tying them to the masonry above. We used 8mm lateral restraint ties installed through the external masonry, tying into the floor joists. Cracking to bay windows is a common defect to period properties that should not be ignored. Traditional costly, disruptive and time consuming methods such as take down and rebuild can be avoided with the utilisation of modern methods of masonry repair.

The extension had been built on inadequate foundations causing it to subside leaving the addition with cracking in various areas. We were asked to design a scheme that would restore the structural integrity of the masonry where cracking had occurred and prevent any further subsidence. As the homeowner had already used a large amount of their savings and a failed claim to the insurers, we monitored the movement and designed a bed joint reinforcement scheme that would restore the structural integrity alleviating the need for piling or underpinning. Deep masonry beams were installed to the external skin of masonry wrapping around the structure along with deep masonry beams to the internal skin tying to the external structure. Crack Stitches were also used to tie separated masonry to the internal skin. The repairs were made good with local areas of plastering and repointing. The movement was monitored for 12 months and there was found to be no further movement and the repairs were guaranteed against failure for ten years.

The property is believed to have been constructed in the early 1830’s and has stood the test of time although falling into a state of disrepair this property was of high value considering its location. The property was in the process of being converted into high specification flats. We were called upon to provide an external survey as diagonal cracking was evident above window openings, cracked bricks and signs of bowing masonry. The bay window at the front of the property was originally a three storey bay window but the ground floor had been removed and RSJ’s installed to support the masonry above. Our survey concluded that brick arch lintel failure was present along with a lack of [lateral restraint](https://newmans.com/services/building-and-structural-repairs/lateral-restraint/) causing a bow in the masonry at floor and ceiling levels. As well as these structural defects we discovered that the construction of the external masonry was believed to be of thirteen inch solid wall construction which is common given the height of the property, upon closer inspection we discovered that the wall construction was actually nine inch solid wall with a single skin external façade which was at no point tied into the internal skin. We were asked by the main contractor’s structural engineer to provide a remedial solution that would restore the structural integrity causing as little disruption to the original façade retaining the aesthetics of the property. Our solution was to create [masonry beams](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2/) using Twistfix helical rods embedded in grout above the window openings to distribute the loads, 450mm stainless steel ties vertically installed through the lintel pinning the lintel to the masonry above and the bed joints raked out and injected with Twistfix resin alleviating the need for disruptive and costly remove and rebuild techniques. The bowing masonry was repaired using a combination of bed joint reinforcement and lateral restraint ties. Bed joint reinforcement is used to create beams in the masonry and drilled into the internal leaf of the masonry restraining the outward force. Lateral restraint ties are installed through the brickwork and into the timber floor joists and are then fixed using resin. This method of repair is similar to the large tie bars which are present on many period properties, but this method is far simpler and faster to install also causing less disruption internally. ## Installing Lateral Restraint Ties With the construction of the masonry providing major concern to ourselves and the structural engineers involved with the project it was essential we designed and implemented a repair solution that would restrain the external skin of masonry and prevent it acting as a free structure with the potential for collapse. Twistfix 9mm remedial wall ties were used at 450mm centres offering 4 ties per square metre. Pull out tests were carried out to 50% of the ties installed achieving well over the 2 KN’s of pull-out force required. The installation of the ties was very quick with only a 6mm pilot hole required and no setting times for resins or grouts with this dryfix method enabling the ties to become load bearing instantly. As well as structural defects aesthetical repairs were required to the stone window cills and ornate decorative features. These were repaired using a range of concrete and stone repair mortars matching the existing profiles and once decorated looked like new. Over 200 bricks were found to be suffering from freeze thaw cycle causing damage, spalling and discolouration to the face of the brick. Utilising specialist brick repair mortars the [bricks were restored](https://newmans.com/services/total-wall-care/brick-tinting/) and tinted to match the existing masonry. The restoration was carried out in less than two weeks fully restoring the external elevations structurally and aesthetically.

The Grade II listed building, which is now a branch of Wagamama, was erected in 1913 and was first listed as a building of special architectural or historical interest in 1954. In more recent years the building has been extended to the rear and now comprises of 4 stories of luxury apartments. The concrete balconies had suffered cracks and corrosion caused by water ingress and carbonation and had lost their structural integrity. Following the survey we were contracted to carry out repairs to the [balconies and walkways](https://newmans.com/services/balcony-and-walkway-repairs/). The concrete undersides, front edges and top sides of all three balconies were hammer tested and all loose and defective concrete removed. Any exposed steel reinforcing rods that were corroded were cleaned to sound steel using mechanical abrasion and all areas of the balconies were grit blasted using our Safe Blast system to remove any existing coats of paint, failed balcony covering and all evidence of rust from exposed steel. All exposed steel was then treated with Sika® 610 Cementitious Based Steel Reinforcement Primer and Bonding Bridge. All cracks to the balcony topside were then cut out to at least 30mm either side of the existing crack. These were flushed with water and RPM Belgium ready rep asphalt repair mortar was applied. Sika® MonoTop-615, a cement based polymer modified high build repair & reprofiling mortar and Sika® Rapid Repair Mortar a fast setting cementitious repair mortar, were applied to all exposed areas requiring repair. Due to the depth of the required repair this was done in layers ensuring the mortar was well compacted and bag rubbed to gain a high bond with the existing concrete. Due to the complicated profile this required high degrees of skill. Sika® MonoTop-620 a cementitious polymer modified mortar was then applied in a 2mm layer ensuring a smooth and flush finish. The balcony topside, up-stands and front edge were pressure washed to remove all dust grease and dirt. A minimum of 3 coats of RPM Belgium Vulkem Waterproof anti-slip walkway coating was then applied to the balcony topside, up-stands and front edge. This was followed by a thick layer of anti-slip sand and seal. Pure brilliant white Flexcrete Monodex Ultra Series 2 Anti-carbonation coating was applied to the balcony underside and concrete front edge. This is a high performance specialist coating that resists carbonation and allows any trapped moisture to escape through the coating without bubbling or peeling. Balcony undersides were also repaired and decorated to complete the restoration. --- ### [Replacement of Inadequate Timber Frame Wall Ties](https://newmans.com/case-studies/replacement-of-inadequate-timber-frame-wall-ties/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Following a failed National House Building Council (NHBC) inspection, due to inadequate timber frame wall ties on a new housing estate in South Wales, Newman’s were selected to rectify the situation. During the [NHBC](http://www.nhbc.co.uk/AboutNHBC/ "About the NHBC") inspection it was found that the 160 properties, which have a timber frame construction, were not structurally sound because their brick facades had not been effectively secured to the timber frames but had simply been nailed to the adjacent plywood sheeting. This is a common defect in new timber frame construction where the main structure of the building is effectively a self-contained timber frame with an external brick facade. In order to ensure structural integrity and to protect against the bricks falling away from the building, the bricks need to be tied to the timber frame at regular intervals. In this development, by one of the UK’s largest house builders, the method used was inadequate. The developers contacted [Twistfix](https://www.twistfix.co.uk/timber-frame-houses-common-defects "Twistfix website"), the leading supplier of specialised building products who in turn recommended Newman’s to carry out the work. Twistfix manufacture and supply timber frame wall ties. These are highly engineered, self-tapping, stainless steel rods that are incredibly efficient and the most flexible available on the market today. A high degree of skill is required in wall tie replacement. First, the structural, timber studs have to be located in order to ensure a secure fixing point. We then install the wall ties at a rate of 4.4 per square metre and carry out random tensile tests on at least 10% to ensure that they meet performance requirements. When retro-fitting wall ties on existing buildings the wall ties are inserted through the centre of the brick because the strength of the existing mortar cannot be guaranteed. However, with this development the house builder was able to guarantee the strength of the existing mortar because it was brand new. We therefore inserted the Twistfix, CE-Marked wall ties into the mortar bed of the brick facade and into the timber stud. This provided an extremely secure, screw-in connection. Resin adhesive was then used to encapsulate the wall tie into the mortar bed, followed by a layer of mortar which was exactly the same as the original. This provided a completely invisible remedy. Using remedial wall ties has saved the house builder tens if not hundreds of thousands of pounds and a huge amount of time as their only other option was to take down and rebuild the brick facades. Installing timber frame walls ties uses the same technique as that demonstrated in the video below but without drilling the pilot hole into the timber. ## Remedial Wall Ties Newman’s can help to diagnose structural defects, cracking and movement by arranging a free Structural Survey. Contact London, the South East and the South West’s leading structural repair specialists for help, advice and peace of mind. --- ### [Brick & Stone Cleaning, Repair & Restoration](https://newmans.com/case-studies/brick-stone-cleaning-repair-restoration/) **Published:** August 23, 2016 **Author:** Support Department **Content:** Newman’s recently completed a project to clean, repair and restore a brick and Portland Stone façade in Mortimer Street, London W1. The brickwork was suffering from a build-up of carbon and grime and the Portland stone, which had previously been painted, had areas of damage and the paint had deteriorated with areas of flaking. The [brick and stone cleaning](https://newmans.com/services/total-wall-care/facade-cleaning/) was carried out using the Doff cleaning system. The Doff is a self-contained unit that superheats water to a temperature of 150oc and allows the operator to adjust both the temperature and the pressure. Because the Doff cleans using high temperature, high pressure steam it is ideal for removing all manner of substances without causing any damage to the building material. Areas of damaged stone were then repaired using Stone Repair and Restoration Mortar. Stubborn areas of paint were treated with a paint de-bonding solution which was left to react before being re-cleaned. As you will see form the images, the final result was very impressive and returned the brick and stone to its former glory. --- ### [Foundational Movement](https://newmans.com/case-studies/foundational-movement/) **Published:** February 23, 2017 **Author:** Jon Newman **Content:** Foundational movement had occurred to this property in South East London due to a couple of problems. First was that the main drain by the front corner of the property had been leaking for a number of years and this has caused the front left corner to subside resulting in the internal and external movement and severe cracking to the brickwork. There was also a lack of wall ties tying the internal and external masonry leaves which may have compounded the problem. ![Front Elevation of House Suffering Foundational Movement](https://newmans.com/wp-content/uploads/2017/02/1-768x1024.jpg "Foundational Movement | Newman's - Structural Repair Specialists") The repair method specified by our engineers was to tie the two skins of brickwork together and to install [helical masonry beams](https://newmans.com/services/building-structural-repairs/bed-joint-reinforcement/) to bridge the soft area of ground and to distribute the loadings to the good ground. This would negate the need to install any underpinning or piling. [![Engineers Repair Specification](https://newmans.com/wp-content/uploads/2017/02/NBS-2833-1024x907.jpg "Engineers Repair Specification | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/2017/02/NBS-2833.jpg) Newman’s installed helical masonry beams into the bed joints to distribute the loads, taking the loadings away from the windows where the lintels have been weak. New [wall ties](https://newmans.com/services/building-structural-repairs/wall-tie-replacement/) were installed at 900mm x 450mm centres to connect the external masonry to the internal masonry, this negated the need to have to install the masonry beams to the internal elevation. [![Bed Joints Cut for Masonry Beaming](https://newmans.com/wp-content/uploads/2017/02/20160322_090741-1024x768.jpg "Bed Joints Cut | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/2017/02/20160322_090741.jpg) All internal cracks were reconnected using Steadfast Thor Helical crack stitches. [![Structural Movement Monitor](https://newmans.com/wp-content/uploads/2017/02/IMG_2227-300x225.jpg "Structural Movement Monitor | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/2017/02/IMG_2227.jpg) Once the works were complete we monitored the property for a year to make sure that the specification and installation were effective and that no additional movement had occurred. During the 12 month monitoring the walls did not even move 1mm. [![Structural Movement](https://newmans.com/wp-content/uploads/2017/02/IMG_2287-1024x768.jpg "Structural Movement | Newman's - Structural Repair Specialists")](https://newmans.com/wp-content/uploads/2017/02/IMG_2287.jpg) The specification was the most cost effective repair method for the client and it negated the need for piling and underpinning which would have been far more expensive. The repair is covered a 10 year insurance backed warranty which enabled the client to get his mortgage. --- ### [Bowing Masonry Repairs](https://newmans.com/case-studies/bowing-masonry-repairs/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s work closely with many building and refurbishment contractors across the South and have carried out repeat business with London based City Line Construction Ltd who are a well-respected general refurbishment contractor. We were called in to carry out a structural survey to a property they were in the process of refurbishment in Fulham, South West London. The bay window was causing major concern due to cracks which were widening daily caused by the bay window pulling outwards from the main structure. The cracks were monitored and a structural repair programme was designed to restrain the movement and tie the bay window into the main structure with minimal disruption. This type of structural defect is common with period properties and is often caused by the foundation to the bay window usually being either a 400mm slab or corbelled footings which are inadequate. Due to the nature of the movement, being an outward bow from the top, the requirement for underpinning is often unnecessary. Twistfix bed joint reinforcement was used to create masonry beams which were wrapped around the bay window offering restraint against the bowing masonry. In addition to the bed joint reinforcement 450mm pinning ties were used to stitch cracks through the brick which offers a fast and effective instant load bearing solution resisting further cracking. Cracks were also injected with Twistfix unique Who-60 grout. Aesthetic brick repairs and repointing was also carried out prior to the external re-decoration by City Line Construction. --- ### [Retaining Wall Restraint - North London](https://newmans.com/case-studies/retaining-wall-restraint-north-london/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Newman’s were called upon by a structural engineer who had surveyed a large retaining wall that was showing signs of major distress with cracking and bowing of the wall putting the structural integrity of the masonry and buildings beyond it in jeopardy. We were asked to design a lasting **Structural Repair Solution** that would restrain the wall and prevent further lateral movement and separation of the brickwork. Along with our workmanship guarantee the client requested an insurance backed guarantee to cover the repairs. Prior to the design of a repair system we carried out a range of site investigations. Soil investigations were carried out at various locations along the wall so that we could be sure of the soil conditions. The services were CAT scanned to mark their location and drainage behind the retaining wall was inspected with a [**CCTV drainage test**](https://newmans.com/services/Drainage-Surveys) to ensure there were no failed drains. On completion of the site investigations our in house team of experienced surveyors and engineers designed a repair scheme that would incorporate the **[Twistfix Helibeam system](https://newmans.com/services/building-and-structural-repairs/bed-joint-reinforcement-2)** and [Cementitious Sock Anchors](https://newmans.com/services/building-structural-repairs/cementitious-sock-anchors/) to restrain the bowing wall, distribute structural loads and tie the cracked brickwork. Twistfix Helical bars were installed into the bed joints to create deep masonry beams within the existing brickwork. This method of reinforcement ties the cracked brickwork together and also distributes the alternating structural loads. It also allows some degree of flexibility to prevent ‘hard spots’ occurring which could create further stress to the masonry. To areas affected by severe lateral movement, sock anchors were used to tie R.S.J’s to the brickwork into concrete pads behind the retaining wall achieving extremely high pull out loads as required by the engineers. Areas of Deep Bed Repointing were also carried out using special lime putties which prevent moisture penetration and damage caused by the freeze thaw cycle . The works were carried out in a 3 week timescale which saved the client considerable costs, disruption and time compared to traditional remove and rebuild techniques previously proposed. --- ### [Crack Repair and Building Stabilisation Oxford City Council](https://newmans.com/case-studies/crack-repair-and-building-stabilisation-oxford-city-council-job-no-1856/) **Published:** August 23, 2016 **Author:** Jon Newman **Content:** Having previously completed a number of structural repair projects for Oxford City Council we were contacted investigate one of their properties that was due to be updated as part of their Green Deal programme and was found to be suffering from internal and external cracking. Our investigation included soil testing, cctv camera drainage tests to ascertain the condition of the underground drains and the installation of crack monitoring Tell-Tales. The survey revealed extensive external cracking to the front and gable elevations and internally in the lounge, the bedrooms and the landing. The cctv footage revealed the cause of the problems to be a broken drain gully. Water had washed away surrounding soil and eroded masonry down to the concrete footings. The footings themselves were undamaged. Our repair specification comprised of removing and replacing the damaged masonry down to the existing concrete footings, replacing the damaged drain and relaying the concrete garden path. The cracks were all raked out, cleaned and injected with thixotropic cementitious grout. A combination of [crack stitching](https://newmans.com/uploads/downloads/NBS-CS-SK01.pdf "Crack Stitching - Standard Method") and [bed joint reinforcement](https://newmans.com/uploads/downloads/NBS-LR-SK05.pdf "Masonry Beaming - Standard Method") using the Twistfix Heliforce system was employed to stabilise and reinforce the masonry. All areas of plaster and render that had been disturbed during the repair were made good. As part of the refurbishment of the property Oxford City council then installed external insulation and cladding. ## Crack Repair Our client base ranges from private domestic customers, housing associations and councils to structural engineers, building surveyors and loss adjusters. [Contact](https://newmans.com/contact/contact-form) us today to discuss your requirements. --- ### [Victorian Concrete Step Repair](https://newmans.com/case-studies/victorian-concrete-step-repair/) **Published:** August 15, 2017 **Author:** Jon Newman **Content:** The original timber lintel between the concrete steps and the front door of the basement flat on this three storey, Victorian property in West London was rotten. The rot was probably caused by water ingress through minor cracks between the top step and the wall. Due to the failure of the lintel, some movement had occurred causing further cracks in the concrete steps which exacerbated the problem. To restore the structural integrity of the steps, the old timber lintel was replaced with a new concrete one and timber floor joists that had been damaged by damp were repaired with new spliced sections. [Jahn M60 Plaster Mortar](https://steadfastspl.com/jahn-repair-mortars/jahn-m60-plaster-mortar/) was then used to repair the area underneath the steps and above the door. [Concrete Repair](https://newmans.com/services/concrete-repair-solutions/) For the concrete step repair, all loose concrete was removed and cracks were cut back to stable material. [Jahn M90 Concrete Repair Mortar](https://steadfastspl.com/jahn-repair-mortars/jahn-m90-concrete-repair-mortar/) was then used to repair all damaged areas. We use Jahn Repair Mortars due to their high quality and their long history of being failure free. [Waterproofing](https://newmans.com/services/balcony-and-walkway-repairs/balcony-walkway-waterproofing/) The client chose to have the steps coated to provide a waterproof, durable, non-slip surface. After allowing sufficient time for all of the concrete repairs to go off, a coat of Resiplast PMMA Concrete primer was applied to the entire area. A layer of Resiplast Polyac liquid membrane was applied and spread level across the steps, building up sections in the middle of the steps where water had previously pooled. This was followed with a layer of Polyac Top Coat in the customer’s chosen colour, which was then covered with a generous amount of quartz, also in the customer’s chosen colour. The quartz was brushed all over the surface area and the surplus material removed. As well as being aesthetically pleasing, the quartz provides a non-slip surface and adds to its durability. A final layer of top coat was then applied to seal the quartz and to provide UV protection. Both matt and gloss finishes are available and the client chose matt on our recommendation. Both ourselves and the client were extremely pleased with the result. Please [contact us](https://newmans.com/contact-us/) for step repairs and waterproofing for balconies and walkways. --- ### [Rapid Cure Concrete Repair and Waterproofing](https://newmans.com/case-studies/rapid-cure-concrete-repair-and-waterproofing/) **Published:** February 11, 2019 **Author:** Jon Newman **Content:** ### Issue / Problem The existing asphalt floor covering of this residential block of flats in Northampton had de-bonded from the concrete causing water ingress from the walkways into the flats below. The drainage gullies were also broken and caused saturation of the concrete floor slab leading to oxidation of the steel reinforcement, with water dripping through the concrete slab. ### Repair Specification / Solution The existing asphalt was removed from the balcony to expose the concrete walkway including the non-slip tiles. The existing gullies were removed /along with the existing downpipes to be replaced with new. This will allow excess rain water to drain away and prevent it from escaping into the concrete walkway. The spalled concrete from the underside was cut back to reveal the oxidised steel. This was repaired using the [Kimia Betonfix Monolite R](https://steadfastspl.com/kimia/betonfix-monolite/) – Rapid Cure Concrete Repair Mortar from [Steadfast](https://steadfastspl.com/). A new fairing coat was applied to all concrete surfaces under the second-floor staircases and balconies. A new waterproof non-slip coating is to be installed using Steadfast’s [Polyac Rapid System](https://steadfastspl.com/applications/polyac-rapid/) by Resiplast. The fast cure system was installed to all surfaces including upstands, stairs and second floor balconies. ### Result The client chose the new floor covering colour from the extensive range that Steadfast provided. The Polyac Rapid system was chosen for its fast curing, durable and non-slip characteristics. With only 30 minutes of drying time between each coat, disruption for the tenants was greatly reduced. Where appropriate Newman’s use the latest technologically advanced products to reduce cure times and therefore disruption. This includes Betonfix “one bag” concrete repair system which uses additional fibres to provide additional strength and has two options: Monolite R – rapid cure or Monolite N – normal cure, we were able to provide the client the best possible solution to keep the tenants happy. The new flooring is easy to clean and was supplied with a 10 year manufacturer’s product warranty. --- ### [Decorative Waterproof Coating and Concrete Repair to Steps](https://newmans.com/case-studies/decorative-waterproof-coating-and-concrete-repair-to-steps/) **Published:** April 30, 2019 **Author:** Jon Newman **Content:** A client in South West London contacted us to repair the concrete steps leading up to their property. There were cracks in the concrete and vegetation growing through the steps which was allowing water to leak into the store room below. The steps were worn and uneven and there was a hole in the bottom step. The hole and cracks were cleaned back to solid material and repaired using Betonfix R, rapid curing concrete repair mortar from [Steadfast Specialist Products](https://steadfastspl.com/). Because of the need for levelling as well as waterproofing the steps, Steadfast’s Polyac® Rapid System 3 was used. Polyac® Rapid System 3 comprises of 5 layers that seal, level and waterproof steps, walkways and balconies, as well as providing a decorative, anti-slip, wear layer. Each layer of the decorative waterproof coating system cures in under 30 minutes which significantly minimises disruption to tenants. The five layers comprise of the Polyac 18 primer, the Polyac 55 self-levelling screed, the Polyac BDM-M waterproof membrane, the Polyac 65 Top Coat and a decorative quartz wear layer sealed with a further coat of Polyac 65. We offer a multitude of decorative waterproof coatings and for this job our client chose the Wizard finish. You can see a close-up of the finish below. The finish looks fabulous and is protected with a 10-year manufacturer’s warranty. --- ### [Internal Communal Flooring Solution](https://newmans.com/case-studies/internal-communal-flooring-solution/) **Published:** February 7, 2020 **Author:** Jon Newman **Content:** Newman’s were asked to come up with a scheme to provide new communal flooring solution to internal landings and stairs in over sixty blocks of flats in Northampton. As well as looking old and tired, the existing lino and vinyl flooring was lifting in a lot of places and causing trip hazards. So, as part of the maintenance programme, they needed to be replaced and upgraded to modern standards. Newman’s consulted with the client and the brief was for a hard-wearing surface that was easy to for the cleaners to clean but did not cause any issues when cleaning with water. Because the Polyac RAPID system from Steadfast is fast curing, it provides a perfect solution for communal flooring areas such as these, where residents require continued access to their homes. Each coat cures and is trafficable after just 20-30 minutes, causing minimal disruption. We presented a selection of samples showing various colours, textures and finishes available with the system to enable the client chose the best fit. A grey coloured coating with a black, grey and white fleck. With some of the internal stairs being concrete and some of them being timber we had to provide two solutions that would result in the same finish. For the concrete areas, the existing floor covering was remove and Polyac primer for concrete was applied. Once cured, Polyac 55 was applied to level out any unevenness. Once this had cured grey coloured the Polyac BDM membrane was applied. Before this had cured it was broadcast with the 5mm fleck to give the required decorative finish. This was then sealed with the Polyac 61 clear, flexible topcoat. For the timber areas, the existing floor covering was removed, primer applied and then fleece mesh was installed over the joins to protect against cracking and to assist in providing a seamless finish. Once again, Polyac 55 was applied to for levelling, followed the grey BDM membrane, the fleck and Polyac 61 flexible topcoat to give exactly the same finish as with the concrete. For health and safety requirements, the stairs then had new bullnoses fitted. The client and the residents were extremely pleased with the result. See the gallery below for a few images before, during and after installation. --- ## Categories ### [Building and Structural Repairs](https://newmans.com/category/building-and-structural-repairs/) **Description:** Newman Building Solutions -
