Cavity Wall Tie Replacement

Since the beginning of the 20 Century, cavity  walls have been used to offer better protection from the elements and reduce the amount of heat loss through the external perimeter walls. The construction comprises of two walls separated by a cavity. These walls are ‘tied’ at strategic intervals using various forms of wall tie, commonly made of metal and often coated in bitumen or zinc.

In the 1980’s it became apparent that the wall ties deteriorated much quicker than anticipated leading to Cavity Wall Tie Replacements being required.
