Crack Stitching Bar – 6mm X 7000mm


Crack Stitching Bars are made in stainless steel and helical in shape, which makes them twice the strength of a rebar, four times that of an epoxy glass-fibre rod and seven times that of a flat twisted plate.

SKU: N/A Categories: ,

Patented helical Crackstitching Bars for masonry repairs to walls and brickwork. These twisted crack stitching bars comprise 6mm high tensile (circa 8kN) stainless steel helical ties that are bonded across cracks in a wall to increase the tensile and flexural strength of masonry. The cracked wall is reconnected, tensile forces redistributed along the full length of the bars helix and the stabilised structure restored to full strength.

The helical bars are bonded into place using a cementitious masonry repair grout such as Thor Helical Remedial W 60 Flexi-Grout.

Available in standard 6mm diameter or 8mm diameter as well as in 1000mm, 2000mm, 3000mm and 7000mm length.  Visit our Crack Repair Category for more sizes.
