Cracks in brickwork are rectified by adopting the following procedure:
- If the cracks are less than 1.5 mm in width, the cracks may be filled with commercially available putty.
- Wider cracks are repaired by releasing them out to about 25 mm and re-filling with 1 cement, 2 lime, 9 sand mortar or any crack-filling material available in the market.
- Still wider cracks may have to be stitched by using reinforced mortar or concrete stitching blocks.
