The decent homes scheme is still running and Newman’s work with many main contractors on window replacement schemes and External Wall Insulation contracts in order to repair masonry and allow the safe upgrade of properties.
Bed Joint Reinforcement
Often with window replacement schemes it is discovered that lintels are defective and in some instances have even collapsed upon removal of windows. We carry out lintel surveys on behalf of the council or the main contractor and specify repair programmes that will not hold up the schedule and will restore the structural integrity of the brickwork saving time and money on costly lintel rebuilds.
Lintel Failure
Wall tie failure is another common structural defect within social housing due to many properties being built within the 1930’s to 1960’s using iron fishtail ties which have corroded and failed or in some instances simply a lack of wall ties have been installed during the construction phase. Only specialist contractors like us should be used for wall tie replacement schemes.
Wall Tie Failure
Often these structural defects only come to light whilst other trades are on site requiring us to have a fast turnaround, we can normally attend site within 24 hours and will design a repair strategy on site using our in house surveyors.
If you are currently working on any social housing schemes that require our services please do not hesitate to contact us right away.
Newman’s teams of Structural Repair Technicians have begun works across London and the South East restoring the Structural Integrity of Failed Masonry.
Investigation works are underway at a block of low level flats in Oxford to discover the cause of subsidence. Investigation works include CCTV drainage inspections, Water pressure testing of incoming mains water supply, Soil investigations and structural diagnosis.
Structural Inspections
Bay Window Repairs are underway in Fulham, South West London for one of our Principal contractor clients. Newman’s were called in to carry out a Structural Survey and crack monitoring as the bay window was moving outwards causing major concern. A structural repair specification was designed and installation has begun incorporating Twistfix’s Bed Joint Reinforcement and Lateral Restraint Ties which will be provide a permanent insurance backed solution.
Bay Window Restraint
Concrete repairs and Anti Carbonation coatings are underway in North London to a commercial shopping precinct and the social housing above as vertical and horizontal cracking had appeared across the structure. the cause of cracking was identified as lack of cover to the concrete reinforcing causing oxidastion of the reinforcing rods and spalling the concrete. An anti carbonation coating is also being spray applied to the concrete structure after the concrete repairs.
Bulging walls in period properties are a common defect that are often seen along the gable and flank elevations of a property. This defect is especially common in Edwardian and Victorian properties but is also evident in properties of all ages.
Bowing Wall
Bowing 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
Lateral 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.
Wall Tie Failure Caused Bowing Walls
In modern properties or buildings constructed with a cavity wall then the bowing if not confined to the floor joist levels only could indicate that there are other structural defects such as wall tie failure which will need to be assessed.
Out lateral restraint schemes for bowing walls can be guaranteed for ten years covered by an IGL insurance backed guarantee. Contact us today if your property is showing signs of outward movement.
