Crack stitching bars provide a permanent solution for masonry repairs and cracked wall reinforcement to suit vertical, stepped or corner cracks in masonry. Crack repair bars are simply and effectively grouted across cracks in walls to reconnect and strengthen masonry.

Helically twisted crack stitching bars are used to reconnect and reinforce cracked masonry walls and brickwork. These 6mm profiled and twisted stainless steel  bars are bonded across cracks in a wall to increase the tensile and flexural strength of masonry. In use the high tensile (circa 9kN) reinforcing bars redistribute tensile forces along the full length of the helix and provided added resilience to shear loads to fully restore the stabilised structure to full strength.
