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