Cavity Wall Tie Replacement

Cavity walls are commonplace in buildings erected since the start of the 20th Century, and were designed to improve protection from natural elements and reduce unnecessary heat loss from the property.

Cavity walls consist of two walls, tied together at strategic intervals with a special wall tie, usually made of metal coated in zinc or bitumen. In the 1980s it was discovered that these wall ties deteriorate more quickly than was anticipated, meaning that many properties are now suffering from problems such as stepped and horizontal cracking of the masonry or mortar and bulging walls.

Wall Surveying

Using specialist detection equipment, ProTen Services’ surveyors are experienced in locating and assessing the condition of existing cavity wall ties, and will be able to recommend the most suitable method of remediation. Once replacement wall ties have been fitted, the wall will be left stable and with a very high standard of cosmetic finish.
