Cavity wall tie failure occurs for a number of reasons however the most common cause is inadequate materials being used when the wall ties were first made, other causes include a chemical reaction to the mortar for example black ash mortar or corrosion from driving salt laden rain in coastal areas.

Cavity wall ties are embedded into the outer and inner faces of the wall, when a steel wall tie corrodes or rusts it expands causing the outer wall to crack or bulge sometimes the roof edges can lift and cracks can be seen internally, alternatively some properties have wire ties which can disintegrate to nothing leaving the outer wall at risk of collapse.

If any of these signs are seen the first step is to carry out a comprehensive survey to determine the extent of the problem and our surveyors are trained to carry out these surveys using a variety of tools to identify the location and examine the condition of the cavity wall ties.
