Tuckpointing is the process of removing deteriorated mortar and installing new mortar between masonry units. Typically, the mortar joint will be removed by the total width of the joint and 3/4 of an inch deep. A circular diamond blade is used to grind the existing mortar-joints deep to allow the new mortar to be filled deep between the bricks or stone. This makes a strong mortar joint and helps the new mortar to adhere.
Inspecting masonry conditions on your building
Deteriorated brick or block - Look primarily for damaged caused from cycles of freezing/thawing, Spalling is the deterioration of masonry surfaces and appears in older structures, parapets, freestanding and retaining walls. Isolated spalling at lintels or shelf angles is extremely important to inspect since it may indicate a more serious problem.
Cracked Masonry - One of the principle causes of cracking masonry walls is differential movement. This is the failure of a wall to accommodate this movement over large areas of brick or block, which can cause vertical cracks.
Deteriorated mortar - Check the mortar for cracks, crumbling, erosion more than 1/4" back from the original depth, or missing portions.
Loss of bond between brick and mortar - easily noticeable by a slight gap opening similar to a crack between brick and stone or other masonry units.
