This crack started to develop under the window over the past five years and was a big concern for the current owners. Buildfix discovered a likely cause and was able to come up with a cost effective repair solution that didn't include expensive and disruptive underpinning.

Cause

A leaking bathroom pipe and shower drainage had seeped into the basement for a number of years causing the soils under the foundation to erode very slightly, but enough to cause movement above.

Solution

Before structural works were carried out a plumber was contacted and all pipes and drainage were repaired to stop any further damage to the wall. After all plumbing works were complete Buildfix introduced a crack stitching combined with a masonry beam method to restore structural integrity.
