Does crack stitching work?
Yes, crack stitching is a proven and highly effective method for repairing structural cracks in brick, block, and stone walls. The process uses stainless steel helical bars bonded into the mortar joints with specialist grout to reinforce the wall. When installed correctly, crack stitching restores structural strength, prevents further movement, and extends the life of the masonry without the need for costly rebuilding. It is widely used on both residential and commercial properties across the UK.
What is the crack stitching method?
Crack stitching is a structural repair technique designed to strengthen cracked masonry walls. The process typically includes:
- Inspecting the crack to identify the cause of movement.
- Cutting horizontal slots into the mortar joints across the crack.
- Installing stainless steel helical reinforcement bars into the slots.
- Bonding the bars with a high-strength grout or resin.
- Repointing the joints to match the existing brickwork for a neat finish.
This method spreads structural loads across the wall, stabilises the damaged area, and helps prevent cracks from reopening while maintaining the building’s original appearance.
