Crack stitching

Crack stitching is a permanent and very successful method of structural repair for properties suffering with cracks in the masonry and in the mortar bed joints.

In summary, ‘stitching’ the damaged walls requires using bars grouted (a fluid form of concrete) into the bed joint, overlapping the crack in the wall the same way using thread to stitch two pieces of cloth together.  Compared to past methods, crack stitching is very resilient and a very cost effective solution.

When to use crack stitching

Depending on the size and depth, crack stitching can be used once a signs of cracks in the masonry begin to appear.  The cracks can be horizontal, ‘stepped’ cracking, or a combination of both. Once cracks appear on the external wall, it is critical to reinforce the structural masonry to prevent further damage.

Prior to any work taking place, it is essential the cause of the crack is first established. If you are not an expert yourself, we would suggest you contact a qualified individual such as a structural engineer or ourselves at Peter Cox to inspect the property and recommend the best course of action. Structural repairs can be a complex and require the skills and expertise of an experience individual to assess the damage and find the root of the problem.
 

How Crack Stitching Works/

Repairs carried out using crack stitching will provide resistance against further cracking and strengthen the structure of the masonry, offering a minimum disruption and permanent solution.

The process, very similar to lintel repairs, involves inserting long metal bars into the brickwork bed joints and grouted into place.  It is as follows:

  • Deep chase - Two deep chases are made into the mortar to create a gap in the bed joint.
  • Cleaned and grouted - The deep chases are cleaned out to remove any debris and a bead of grout is injected.  
  • Bars cut to size- High grade stainless helical bars are cut down to size to fit into the bed joint.  
  • Set and Grouted - The bars are then inserted into the bed joint and pushed into the grout. A second bead of grout is then applied on top.
  • Concealed - Once in place, the crack is concealed using mortar to maintain the original style of the property.
