Repointing

Repointing is the process of renewing the external part of mortar joints in masonry construction. This technique involves removing old, deteriorated mortar from the joints between bricks or stones and replacing it with new mortar. Repointing is essential for maintaining the structural integrity of a building, as deteriorated mortar can lead to moisture infiltration, weakening the masonry over time. The new mortar must match the original in composition, texture, and color to ensure a seamless repair. Repointing not only strengthens the masonry but also restores its appearance, making it a vital process in the preservation of historic buildings and the maintenance of modern structures.
