Our crack stitching bars are reinforced stainless steel rods that are chemically bonded into bed joints. These rods stitch together cracks found within a property, redistributing tensile forces and stabilising structural integrity. The bed joints are cut out with specialist dust extraction cutting equipment and then the crack stitching bar is grouted in place to prevent any future movement.
To finish, our crack stitching bars are hidden on completion, meaning your property can retain the original character of its wall.
Crack stitching is used when a building starts to get vertical cracking. Typically crack stitching is perfect for cracked masonry, but it should only be applied once the cause of the crack has been determined.
Benefits of cracked stitching:
- Quick, simple, effective and permanent.
- The grout combination provides an excellent bond.
- Masonry remains flexible enough to accommodate natural building movement.
- Non-disruptive structural stabilisation with no additional stress.
Installation of our crack stitching bars should cause minimal inconvenience to the occupants of a property. Once the crack has been filled, and re-pointing has taken place, there will be little remaining evidence that our crack stitching bars have been installed.
