Cavity Wall Tie Replacement

Research carried out by the BRE estimates that of the nine million UK properties constructed with cavity walls, almost a quarter of these (2 million) will suffer from wall tie corrosion or failure and will require replacement wall ties.

Our Cavity Wall Tie Replacement work is guaranteed for 20 years.

Wall tie failure occurs for a number of reasons, however the most common cause is inadequate materials being used when the wall ties were 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.

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 and / 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.

Following any replacement wall tie work, it is essential that the cavity is thoroughly cleaned so that any debris from the work does not settle and bridge the property’s damp proof course.
