Our heavy-duty brick stitching kit includes 8 mm helical bars with 25% more strength than other 8 mm helibar-type products. The more robust equipment provides everything necessary to reconnect and reinforce cracked brick, block and stone walls.
The stitching kit contains.
First, cut and remove the mortar along the selected bed joints, 500 mm, on each side of the crack. The height of the cut slot must be at least 3mm more than the bars' diameter. Then, flush the joints with clean water to clean and soak them. Mix the WHO 60 grout per mixing instructions, load the mixture into the dispenser, and fill each slot to two-thirds deep. Now, insert the stainless-steel rods deeply into the grout and trowel all displaced mortar to fully encompass the reinforcement. Lastly, fill the cracks and repoint the wall with matching mortar to disguise the installation.
The encapsulated 8 mm helical bars span the fracture, absorbing stress and redeploying tension forces along the helix. A succession of load-sharing rods forms an area of reinforced masonry that inhibits further crack development. The reinforced zone provides hidden strength within the brickwork and is an ideal retrofit solution for permanently repairing cracks in masonry.
Our easy-to-use kit makes brick stitching rapid and cost-efficient. We stock various stitching kits ready for fast delivery to all UK areas. Click here for help & expert advice.
