As Warrington bricklayers, we undertake masonry pointing for brickwork, garden walls, home improvements, house repairs, and maintenance.
Pointing is the action of filling the gap between masonry units (joints) with mortar to protect the masonry from water ingress and associated decay. In masonry construction, over time, weathering and decay cause voids in the joints between bricks or masonry units, allowing the undesirable entrance of water. Water entering through these voids can cause significant damage through frost weathering [freeze thaw cycle], salt dissolution and deposition.
Pointing masonry helps to deal with deteriorated joints to help against penetrating dampness and the process involves the removal [raking out] of the old mortar and replacing it with new mortar from the face of a masonry joint. This helps exclude the weather and retard deterioration of the wall.
