Implementing a method known as "crack stitching" is the best and most affordable approach to fixing any cracks in your outside walls. Crack stitching involves placing stainless steel helical bars into the wall to keep together the two broken ends, restoring the wall's integrity and preventing further damage.

• First, you have to create a gap in the mortar bed that is over 500mm deep and on either side of the vertical crack according to the wall thickness.

• Make sure the mortar has been fully removed to disclose the top and bottom faces of the stonework.

• Then, you have to flush the joint with water after removing all loose material (you can use a blowout pump for this). Normal vertical spacing between brick courses is 4 to 6, however, if, in question, you can always consult a structural engineer.

• Then you have to thoroughly combine the anchor grout before loading it into the gun using the included paddle mixer. 

• After that, pump the grout to the back of the slot until it is about two-thirds of the way deep in a continuous, even flow.

• Make sure the curved bar reaches 500mm on either side of the crack by pressing it firmly into the mortar.

• Then you can apply a second batch of grout to the slot, covering the bar fully. Then, using the provided trowel, press the grout in until it is about 10 mm from the surface, packing the bar and grout tightly together.

• And at the end, finish by repairing the bed joint and matching-appropriate filling of the vertical crack.
