Crack Repair – Masonry Walls

BrickFix Masonry Crack Stitching Kit

The Brickfix Crack Stitching System offers a fast and cost-effective solution for crack repair in masonry walls.

The system allows cracks in masonry to be stabilised by bonding Brickfix helical crack stitching bar into slots cut into the wall’s mortar course using specially formulated Brickfix grouts.

It should be noted that this method of crack repair can only stabilise the symptoms of cracked masonry walls. It will not cure the cause of the crack (e.g. subsidence). For this reason it is recommended that a structural engineer is consulted before undertaking crack repairs.
