What is Crack Stitching?
Crack stitching is the masonry repair method for repairing cracked walls and ensuring that they are reinforced. Crack stitching bars provide a permanent solution for masonry repairs and cracked wall reinforcement to suit vertical, stepped or corner cracks in masonry.
Crack repair bars are simply and effectively grouted across cracks in walls to reconnect and strengthen masonry. In use the high tensile (circa 9kN) reinforcing bars redistribute tensile forces along the full length of the helix, providing added resilience to shear loads to fully restore the stabilized structure to its full strength.
When Crack Stitching can be used?
Crack Stitching is commonly used for repairing the damaged, cracked Brickwork:
House Brick Wall
Brick Fence
Decorative Brick Constructions
Brick & Block Arches
… anywhere with more than 3 Brick Courses laid
Reasons for Cracks in the Brickwork
Not a secret, that Melbourne mostly situated on Reactive Soils – more in some suburbs, less in others.
Professional Builder MUST take an advice of Geotechnical Engineer before the commencing of construction to go over the test and classify the site classification according to Australian Standard AS 2870/2011 – Residential slabs and footings.
Only after the test it is possible to determine what sort of footing system is suitable for the site.
Unfortunately, some Builders neglect this important step – and that’s when the Cracks happen!
Process of Crack Stitching
– First of all, we took off the render about 100mm both ways from the crack – this way we’re opening the crack to make it obvious and to make sure that the whole crack is well-treated. In the process we’re uninstalling the broken bricks and taking off the cracked mortar as well.
– Next, we’ve cut the horizontal seams about 500mm both ways from the crack with depth of 30-40mm including the render every 3 brick courses. (Specifically in this case every 2 brick courses)
– Washing all the dust off the Cracked Wall with high-pressure.
To stitch the cracks, we’re using the HeliFix materials.
– Filling the cut slots using the Helifix Pointing gun, injecting the stitching product along the whole slot.
– Using the insertion tool, pushed HeliBars into the grout to obtain good coverage.
– Re-pointed the mortar to prepare the wall for rendering.
Enjoy your Crack-Free walls!
