Use our professional crack stitching kit to strengthen cracked masonry at trade prices. Put together by industry experts, the parts are perfect for reinforcing brick, block and stone walls.
The stitching kit comprises:
First, cut or grind slots along the selected bed joints, 500 mm on each side of the crack. Then, clean the joints and soak them with clean water. Mix the grout, load it into the applicator, and fill each slot to two-thirds deep. Push the rods into the grout and trowel the displaced mortar to fully surround the helix. Finally, point the wall with fresh mortar to camouflage the installation.
The helical bars bridge the fracture, absorb stress and redeploy tension forces along the helix. A series of load-sharing rods create a reinforced zone that curtails crack development. The concealed reinforcement restores strength and stability to the brickwork.
Our kit makes crack stitching quick, easy and cost-effective. We stock a selection of crack stitching kits ready for rapid delivery to all UK regions. Click here for help & expert advice.
