Heavy duty helical crack stitching kit that contains all the components needed to carry out heavy duty repairs to vertical or stepped cracks in masonry walls.
Heavy Duty Wall Crack Repair - heavy duty 8mm bars
Our Easi-Fix Heavy Duty Crack Stitching Kit contains all the components needed to repair large vertical or stepped cracks in masonry walls. The ten 8mm helical spiral bars included in the kit provide a permanent repair on large cracks in masonry walls.
Any repairs carried out using this heavy duty crack stitching kit system will stabilise the structure, provide resistance against further cracking and restore the structural integrity of the masonry.
Heavy Duty Crack Stitching Kit Contains:
- 10 x 1 metre x 8mm Helical Spiral Bars
- 1 x 10kg Permacem Anchor Grout
- 1 x Mixing Paddle
- 2 x Nozzles
- 1 x Mortar Gun and Barrel
- 1 x Soft Grip Brick Jointer Trowel
How 8mm Helical Bars Work
The 8mm helical crack stitching bars are installed across cracks in a wall, effectively ‘reconnecting’ or ‘stitching’ the cracked masonry. The tensile forces are then evenly redistributed along the entire one metre length of the steel bar, which restores the structural stability and flexural strength of the masonry.
How to use heavy duty crack stitching kit
Repairs using the Easi-Fix Heavy Duty Crack Stitching Kit are made quickly and easily with the minimum of disruption. They are also inexpensive and won’t cause any further damage to the wall.
Installing 8mm crack stitching bars
The stainless steel helical bars are placed into horizontal slots that you cut into the mortar bed joints across the crack. These can be cut using an angle grinder or a mortar chisel. You grout them into place using Permacem Anchor Grout that sets around the helical bar rapidly developing compressive strength. With the helical bars firmly in place, structural integrity is restored. For full crack repair instructions, please consult your kit or read our How to Guide: Crack Stitching and our How to Repair Cracks in Walls guide for further information.
Installation - Repairing Large Cracks in Bricks & Masonry
Repairs using the Permagard Heavy Duty Crack Stitching Kit are made quickly with the minimum of disruption, are inexpensive and cause no further damage to the wall. The stainless steel helical bars are placed into horizontal slots which are cut into the mortar bed joints across the crack and then they are grouted into place using Permacem Grout (provided in the kit).
Permacem Anchor Grout is a shrink compensated grout with added polymer additives which sets around the helical bar and develops compressive strength rapidly to prevent axial deflection of the helical bar under load conditions.

What is the difference between the 6mm and 8mm helical bars?
The 2mm extra in the diameter of the 8mm helical bar increases the tensile load by 25% over the 6mm bar. It is therefore more suited to larger cracks. The 6mm helical bars feature in our standard crack stitching kit and the 8mm in the Heavy Duty version
Can the PermaCEM grout be used in parts rather than all at once?
Yes, our PermaCEM grout is mixed onsite by simply adding water to the required amount of powder. This means you can use as much or as little as required for the job
