Cavity Wall Tie Replacement
Since the beginning of the 20th Century, cavity walls have been used to offer better protection from the elements and reduce the amount of heat lost 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.
Since the 1980’s its become apparent that the wall ties deteriorated much quicker than anticipated leading to cavity wall tie replacements being required. According to the BRE, ten million homes in the UK may already have this problem yet to be diagnosed.
