What is brick repointing, how is it done and when do you need to repoint brickwork?
Brick repointing is the process of renewing mortar joints in masonry construction. Over time, through weathering and decay the mortar joints between the masonry units (usually bricks) corrode and fail. Allowing the undesirable ingress of water. Water entering through these voids can cause significant damage through freeze/thaw cycles and from salt dissolution and deposition.
How is brick repointing done?
Our brick repointing process begins by removing damaged pointing to a depth equal to or slightly more than the width of the joint. Removal of old mortar between joints is done carefully to avoid damage to masonry units. This process is carried out using angle grinding equipment fitted with dust extraction hoods and high powered dust extraction units.
The new mortar is gun injected into the joints filling them from the back to the front to ensure there are no hidden air pockets for water to lodge, and no risk of subsequent frost damage. This system allows our operatives to achieve a high quality finish far quicker and cleaner than using conventional methods.
New mortar can be designed to match the color and profile of existing mortar to avoid visual aberrations. It is essential that the mortars used for repointing have similar performance characteristics to the original mortar used in a building. Such performance characteristics include permeability, compressive strength, and coefficient of thermal expansion. For instance, if a soft lime based mortar was originally used, the most appropriate brick repointing mortar is likely to also contain a large amount of lime.
