Cracked Wall Repair
For suitable masonry cracks, stainless-steel helical reinforcing bars, commonly known as HeliBars, can be installed into the existing mortar joints. The HeliBars and specialist grout work together to reconnect and reinforce the cracked masonry and distribute loads across the repaired area. This provides a strong, durable repair while retaining the existing wall.
Cracks and loose brickwork can have several different causes. The right repair starts with understanding what's happening with the building.
Why should I repair the crack?
Not every crack is structural, and sometimes filler and paint may be all that's needed. In other cases, cracking can indicate something more – such as ground movement, water ingress, tree roots, drainage, or an issue within the building itself.
If foundation movement is contributing to the problem, underpinning may be recommended to re-support and stabilise the footings. This may involve another qualified contractor specialising in resin injection underpinning – a modern and less invasive method, or traditional underpinning, which involves excavation and concrete works beneath the existing footings.
Underpinning addresses the support at foundation level, but it doesn't necessarily repair the damage caused to the walls above. Our Propping, HeliBar crack stitching and HeliTie remedial wall tie systems can work alongside underpinning to reconnect, reinforce and stabilise affected masonry — enhancing the results of underpinning alone and providing a more complete remedial solution.
