Brick stitching cracks This Derbyshire stone built property in the peak district had an historic settlement crack running vertically up the gable. The owner was renovating and refurbishing the property and asked us to structurally stitch and resin inject the crack lines. As you can see straight lines are difficult to achieve. Restored both sides of the wall and made weathertight. A 10 year insurance backed warranty was also included in the price. We often get asked to repair all sorts of interesting properties using our resins, mortars and grouts.
