Cavity Wall Tie Replacement

 

Cavity wall tie corrosion occurs when the wall ties embedded in a wall corrode because their protective coating breaks down. This can seriously damage external walls and could, in some cases, make a building unstable.

Wall ties are commonly made from iron and steel, which eventually corrode in damp conditions, so are often galvanised to resist corrosion. However over time, the galvanising can break down leading to wall tie failure. Properties that were built with mild-steel ‘fishtail’ ties (between 1920’s  - 50’s) or those with galvanised wire ‘butterfly’ ties (between 1960’s – 80’s) are often susceptible to corrosion.

 

If a problem with wall tie corrosion has been identified, our specialist technicians are fully trained PCA certified to effectively treat the problem by replacing corroded wall ties.

 

This treatment includes:

  • Drilling holes in appropriate areas of brickwork for access to wall ties.

  • Installation of new stainless steel wall ties, which do not corrode.

  • Isolate existing wall ties to prevent further damage.

  • Preserving the facade of your property – cover drilled holes to match the existing wall appearance.

 

Structural Wall Stabilisation & Crack Stitching

 

Over their lifetime, buildings can be subject to movement caused by physical or natural events. In turn, this movement can cause cracking to the walls of the building which, without attention can quickly worsen and leave the property in a potentially unsafe condition. Cracking and deterioration of masonry can also occur as a result of the freeze/thaw cycle, corrosion of embedded steelwork, increased loading an due to inadequate or defective materials having been used.

 

NRG Property Solutions Ltd offer structural wall stabilisation and crack stitching services in the South East

 

In recent years, a cost-effective remedial solution to such problems has been developed. Through the use of helical steel bars, a wall can be re-engineered with little disturbance to the property and virtually no visual impact.

 

Where masonry has cracked, helical bars can be inserted into the appropriate bed joints. This results in the tensile load of the building being redistributed along the masonry to minimise further developments of the crack and stabilise the building. Once repointing has been carried out, there will be little or no visual evidence of the repair.

 

Before any remedial work can be carried out, it is vital that the cause of movement to the building is identified. At NRGPS, our surveyors have experience in diagnosing such problems and, where necessary, can engage a structural engineer to carry out any required calculations or design approvals
