Cavity Wall Tie Corrosion
Cavity wall ties are built into cavity walls to help hold the masonry walls in place. Potentially these wall ties can corrode and snap with age, which can seriously damage external walls, in severe cases affecting the stability of a building. Signs of a possible problem with cavity wall tie corrosion include horizontal cracks within the mortar and bulging brickwork caused by snapped wall ties.
