What is crack stitching?

In the simplest of terms, this is a way of repairing walls that have cracks and ensure they are structurally sound. This involves the retrofitting of numerous bars for crack stitching that are grouted into place across the wall cracks to connect them again and make the masonry more stable again.

Crack stitching is used to stabilize cracked and damaged masonry. We are Crack Stitching Specialists that Specialise in Cracks in Walls requiring Helical Bar or Wall Ties, Remedial Work and/or Damp Proofing.

Buildings can move over time and this can result in cracking which affects the inherent strength of the property. At Structural Repairs, we are specialists at identifying these problem areas and rectifying the problem.

How to stitch a cracked wall

Slots are made into the walls where the cracks are and the crack stitching bars made from stainless steel are inserted. This is normally in the bed joints as it is easy enough to do. These bars are normally high tensile helical rods that have a large surface area and 6 mm diameter.

Grout is used to lock the helical bars and bond them into the wall, so that they are effectively stitched across the cracks to connect the masonry at either side. The helical bars tensile strength is improved by cold worked by a manufacturing process and it is twice as much as a re-bar and 7 times that of a wound helix plate.

When they are using in stitching cracks, high tensile helical bars combine rotational flexibility with axial strength that accommodates the natural movement of the building while it ensures the cracked stonework, block work or brick work is reinforced.

Stitching cracks is the go-to solution in most cases of masonry with cracks and helps to ensure a structure is stable. Epoxy crack filling should be used as a sealant to protect the structure against thawing or freezing or moisture.

Is this the best method to repair cracks in walls?

Crack stitching should be considered only for walls with cracks that are cyclic or non-active. If the cracks is active or live, it is important to identify and resolve the source of the crack before any stitching is carried out. Live cracks can be caused by insufficient lateral restraint ground movement or failed lintels.

The quickest and most reliable way to reinforce walls that have cracks is by stitching the cracks. Furthermore, the bars used in crack stitching can be installed easily and are not disruptive that mean they are a common choice.

If you think you have cracks in your walls and are considering stitching as a serious option for repairing the damage, it is best to speak to an expert about it. They can help you to assess the cracks and determine if stitching is the most viable option. Even if it isn’t, the experts may be able to help point you to point out what the best method of repairing the cracks actually is.

    How do you repair cracks in brick walls?

    The process starts by identifying the affected area. The grout layer between the affected brickwork is then cut into and helical bars are inserted into the brickwork which bind the wall together. The grout is replaced, returning the wall to its original statement. This whole process stabilises the building and the products used have a 10-year manufacturer’s warranty.
