Repointing is the process of renewing the external part of mortar joints in brickwork, stonework, or masonry. Over time, the mortar between bricks or stones can deteriorate due to weather, moisture, and natural wear. Repointing helps restore structural integrity, improve aesthetics, and prevent further damage.
Benefits of Repointing Services:
Structural Integrity: Repointing prevents water ingress, which can weaken the structure over time.
Aesthetic Improvement: Old, crumbling mortar can make buildings look worn out. Repointing restores their original appearance.
Longevity: By renewing the mortar, it extends the lifespan of the wall or structure.
Energy Efficiency: It can also improve insulation by sealing gaps where heat may escape.
Repointing Process:
Inspection: A thorough inspection to determine the extent of damage and which areas need repointing.
Removal of Old Mortar: The damaged mortar is carefully removed to a depth of around 15-25mm.
Application of New Mortar: A fresh mixture, matched to the existing mortar for consistency in color and texture, is applied between the bricks or stones.
Curing: The new mortar is left to cure, ensuring it bonds correctly and sets properly.
Types of Mortar for Repointing:
Lime Mortar: Ideal for older buildings, as it’s more breathable and flexible.
Cement Mortar: Commonly used in modern buildings for its strength and durability.
