Crack Stitching Products
Thor Helical remedial crack stitch bars are heavy duty helical bars (15kN+) and are ideal for the masonry repair of wall cracks where shear strength is an issue. This 6mm diameter wall crack stitching reinforcement offers extra performace to other helical bar type products by significantly increasing the shear, tensile and flexural strength of cracked masonry walls.
The hi-fin design also makes the Thor Helical products ideal for grouting into mortar beds to retrospectively reinforce distressed masonry and to control cracking by distributing forces back into the structure. The various Thor Helical sections are directly proportionate to one another, providing opportunity for cross correlation of performance characteristics to be used in specification design.
