Crack Stitching

Crack Stitching is a method of repairing and stabilising cracked masonry using HeliBars (6mm diameter) bonded into cut slots with HeliBond cementitious grout.

Masonry may move and crack as a result of movement in foundation soils, seismic activity and cyclical wet and dry, hot and cold environmental conditions. Crack stitching reintroduces structural integrity and redistributes structural loads for a quick, simple, effective and permanent solution.

HeliBar bonded into appropriate bed joints or cut slots with HeliBond grout is the solution to the problem of stabilising cracked masonry.

Quick, simple, effective and permanent
More effective in brick/block masonry than simple crack injection
Suitable for all types of masonry including listed and historic structures and those with lime mortar
Fully concealed, non-disruptive repair system
Stainless steel HeliBars and non-shrink
HeliBond grout combine to create excellent tensile strength within the masonry
