What is crack stitching?
Crack stitching is a method for repairing cracks in masonry. In the old days crack stitching was done by removing cracked bricks or blocks and putting in new ones and then repointing. To make sure the bond and integrity of masonry is properly reinstated, cracks are raked out and short lengths of stainless steel are embedded into the mortar to transfer load and stresses across the broken joints. The repair is simple and is well within the capabilities of a competent general builder.
