Wall Tie Replacement

Nationally recognised standards

Brick cavity walls require wall ties for stability and to prevent the outer skin of brickwork from peeling away from the property. Wall ties are generally metal although terracotta and brick ties can be found. Metal ties come in various shapes, sizes and qualities. Some ties were galvanised to prevent corrosion and some ties were simply painted to prevent corrosion. The effects of long term exposure to the elements can cause metal wall ties to rust or corrode. As metal rusts it expands and delaminates and this expansion can lead to horizontal cracking in the masonry bed joints although sometimes the bed joints are thick enough to accommodate the expansion and cracking is not evident. The ties can deteriorate to the extent that they rust away completely and become disassociated with the brickwork. This can lead to distortion and ultimately failure of the outer leaf of brickwork if left unchecked.

Hillbans can carry out a full inspection of your property including an internal examination of cavity walls with an Endoscope to determine the condition of the existing cavity wall ties. We have a range of stainless steel retro fit wall ties to suit your property’s requirements and our operatives are skilled in the installation of these ties to nationally recognised standards. An equally important part of wall tie installation is the removal or isolation of the existing wall ties to prevent further damage to the masonry panel. The importance of this part of the process is often overlooked by those seeking to make short term gains at the expense of long term performance.
