Crack stitching bars provide a permanent solution for masonry repairs and cracked wall reinforcement.  Crack repair rods are simply and effectively grouted across cracks in walls to reconnect and strengthen masonry. The structural repair system integrates the axial strength and elasticity of Thor Helical bars with the properties of WHO60® grout to enhance the tensile, shear and flexural capacity of masonry walls.

The stainless steel crack stitching ties have a tensile strength that is significantly increased during the course of manufacture and a spiral twist that offers the unique characteristic of torsional elastic yield.

WHO60® is a high performance, non-shrink cement based grout that rapidly develops compressive strength and is used to embed the helical bars and to bond them to the masonry to repair cracked brickwork.

Anchored across fractures, the Thor Helical crack stitch repair ties progressively accumulate building loads along the full interlocking length of the helix and disperse them back into the structure to fully reinstate the structural integrity of cracked walls and distressed masonry.  This effective masonry stitching repair provides resilience against further cracking with minimal cost and little disruption.
