Pointing is the action of filling the gap between masonry units (joints) with a mortar to protect the masonry from water ingress and associated decay.In masonry construction,over time,weathering and decay causes 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 helps to deal with deteriorated joints to help against penetrating dampness.
