Structural Repairs,Working With Shop Fitting Contractors

Newman’s have been working with various shop fit out specialist carrying out Structural Repairs that are often unforeseen and have potential to delay that strict deadlines that these contractors must meet.

Newman’s offer an unrivaled service across London and the South East for contracts of this type and in most cases a surveyor is on site with in 24 hours of initial contact to carry out a Structural Assessment in order to design and implement a Structural Repair strategy.

Once our surveyor had carried out a Structural Survey it was discovered that there was numerous causes of concern which were highlighted by some major cracking and bowing to the masonry. A Structural Repair program was designed introducing Twistfix Lateral Restraint Ties, Bed Joint Reinforcement and water repellent masonry facade protection.

Lateral Restraint Ties were installed to the gable elevation were Bowing Masonry at floor joist level was apparent, Lintel Failure had also occurred and Bed Joint Reinforcement was used to create masonry beams without the need for costly rebuilds.

Water penetration to the front elevation had caused a failure to the pointing and spalling of the brick faces. Newman’s carry out deep bed re pointing and inject the masonry with Twistfix WHO-60 grout prior to re-pointing. The spalled bricks were repaired and tinted combined with Water Repellent facade cream which provides a breathable water resistant barrier the facade was saved.

 

The full case study and pictures will be live in our case studies section very soon.

Bulging Walls and Bowing Walls

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 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.

Bridge Reinforcement

Bridges and Viaduct Reinforcement.

Across England there are hundreds of bridges and viaducts constructed from brick and random stone usually built using brick arch spandrels, built well over 100 years ago, having not been designed to meet today’s standards with volume and weight of traffic that we have on the roads and railways today many are in need of reinforcement and repair in order to maintain their use.

Many of these structures have fallen into a state of disrepair and must be reinforced in order to keep them open and serving their purpose. Traditional reinforcement is costly and can lead to major road and rail closures and diversions but Newman’s are able to use modern methods of repair to reinforce these structures.

Utilising the Twistfix system we are able to reinforce delaminated spandrels enabling them to withstand the weights and speeds that road and rail vehicles impose in this modern world.

By installing helical bar to the underside of the spandrel and installing grout ties through the spandrel we are able to provide an engineered reinforcement solution that enables the route to stay open and improves the load capacity of these bridges and viaducts.

Much of the pointing has failed on the large structures and removal and replacement is a delicate process. Newman’s skilled technicians are able to reinstate mortar that’s loose or missing combined with our structural reinforcement scheme we are able to provide a last guaranteed solution.
