Cavity Walls have been a common feature of buildings in the UK for over 100 years. Two leaves of brickwork are held together using metal straps or ‘wall ties’. The cavities between the two leaves of masonry provide an effective barrier to water penetration and also act as a layer of insulation.
In some circumstances these wall ties can corrode of fail, which can cause cracking in the external leaf of masonry, structural movement or in severe cases, collapse of masonry.
We can conduct a wall tie inspection to identify where wall ties have failed and make recommendations for treating the problem. We also carry out a wide range of structural repairs, including Helibar Crack Ties and Lateral Restraints.
