Crack Stitching - For the repair of cracked masonry

Helifix Crack Stitching repairs and stabilises cracked masonry using Stainless Steel HeliBars bonded into cut slots with HeliBond grout for a quick, simple, effective and permanent solution.

Cracked masonry is best stabilised by bonding HeliBar stainless steel bars into appropriate bed joints or cut slots. Tensile loads are redistributed along the masonry to minimise further developments of the crack which may occur with simple injection methods.
