Cavity wall tie corrosion occurs when the original wall ties used in the construction start to corrode and de-bond from the substrate around them. This wall tie failure leads to horizontal cracks in the masonry, which are often first noticed on the exterior of the property. Structural movement can occur when the ground around the property moves or settles, or when structures are built with insufficient foundations.
These movements can result in large horizontal and vertical cracks both internally and externally. Our fully qualified PCA (CSRT & CSSW) surveyors will discuss your wall tie & brick stitching problem with you & provide you with a quote and recommendations for all remedial work required.
