Fixing Cracks in Brick Walls.

Twisted stainless steel rods are inserted into into the walls, stitching the masonry across the cracks at regular intervals. The brick stitching system allows the cracked wall to behave as a reinforced non-fractured unit. Having a helical configuration the crack stitch rods physically interlock with the bonding agent and exhibit a unique and resilient torsional spring-like quality that allows small amounts of wall movement and recovery to occur without brittle failures.

How are helical stitching bars installed?
Installation is not difficult. A horizontal groove is cut in the brick bed joint where installation can be hidden. The grooves are flushed with clean water immediately before the installation of a high performance shrink-resistant cementitious grout. Brick stitching bars are simply pushed into the grout, ensuring full immersion of the bars along their length. The helical bars extend 500mm each side of the cracks to spread loads and disperse them evenly into the wall structure.
