Cavity Walls

Do your walls have horizontal cracks along the brickwork? This occurs when a rusting cavity wall-tie expands, forcing the bricks apart at the mortar joint. Generally, galvanised cavity wall-ties last for approximately 70 years. After this time, ties can begin to be affected by oxidisation, losing strength and becoming defective.

Apex provides cavity wall inspections with the usage of high-tech borescope equipment. If our inspection determines that your walls are being corroded, it is necessary to install replacement wall-ties.
