Replacing cavity wall ties with a remedial tying system is a low-cost alternative to rebuilding walls that are suffering from wall tie corrosion. For 30 years wall tie replacement has become the accepted method of solving the problem of cavity tie failure.
Wall tie failure occurs when the ability of the built-in tie-system to secure the façade wall of a building to its structural frame is compromised. Failure may be due to not enough ties having been incorporated into the build or deterioration of the ties as a result of rust and time.
In the case of wall tie corrosion, the rusting steel generates an expanding build-up of iron oxide layers as the steel erodes. The damage that can be caused by the expanding ties depends on the type of wall tie used in construction.

Sydney’s Coastal Regions – Salt Exposure.
If your home or heritage building is located in Sydney’s coastal regions, it’s more than likely suffering from varying degrees of salt damage, particularly if your building is more than 50 years old.
Salt causes deterioration of wall ties and the crumbling of mortar. In older houses and blocks of units over time, wall ties will rust completely. Therefore leaving a cavity wall unsupported and compromising the safety of your home.
Left unattended, salt damage could lead to a collapse of your outer skin of brickwork. Wall ties are installed using the Thor Helical system, which drills wall ties into both the internal and external brickwork. This procedure is quicker to fix and more cost effective for you.
