Wall cracks between bricks or blocks are one of the most common problems seen after construction. Many homeowners and civil contractors notice hairline cracks near brick joints after a few months.
These cracks not only spoil the wall finish but can also affect durability over time. The main reason behind this problem is usually poor bonding and shrinkage in conventional cement mortar.
Common Reasons for Brick Joint Cracks:
- Shrinkage of Traditional Mortar: Normal sand-cement mortar shrinks while drying and creates stress between the bricks.
- Weak Bonding Between Blocks: Poor-quality mortar does not create strong adhesion between blocks.
- Excess Water in the Mix: Adding extra water reduces mortar strength and increases shrinkage.
- Thick Cement Joints: Thick mortar layers increase the chances of cracking after drying.
- Improper Curing: Fast drying due to heat or poor curing can result in wall joint cracks.
How to Prevent Wall Cracks After Construction?
- Use Thin Joint Application: Thin joints reduce shrinkage and improve bonding strength.
- Maintain Proper Water Ratio: Always use the recommended water quantity.
- Ensure Proper Curing: Proper curing helps walls dry evenly and prevents stress cracks.
- Use High-Quality Block Jointing Adhesive: Modern adhesives provide better adhesion and crack resistance.
