If there are cracks or problems in the actual bricks or stone masonry there could be a larger problem that also needs to be addressed. If there is a larger issue, repointing may cause further damage. If a historic structure needs repointing, building owners usually hire an architectural historian or conservator to help pinpoint the issues. [ 2 ]

Rising damp is the common term for the transport of water in the lower sections of walls and other ground-supported structures by capillary action in porous materials. [25] Although rising damp of up to 5 metres (20') in height has been observed [ 26 ] the height of rise is typically much lower and is rarely above 1.5 metres (5').
Other damaging processes can also involve calcium leaching by water infiltration, physical phenomena initiating cracks formation and propagation, fire or radiant heat, aggregate expansion, sea water effects, leaching, and erosion by fast-flowing water. [1] The most destructive agent of concrete structures and components is probably water.

Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound, and pasted together by mortar.
Autogenous self-healing crack. Self-healing concrete is characterized as the capability of concrete to fix its cracks on its own autogenously or autonomously. It not only seals the cracks but also partially or entirely recovers the mechanical properties of the structural elements. This kind of concrete is also known as self-repairing concrete.
Components on a concrete masonry unit and brick cavity wall. A cavity wall is composed of two masonry walls separated by an air space. The outer wall is made of brick and faces the outside of the building structure. [6] The inner wall may be constructed of masonry units such as concrete block, structural clay, brick or reinforced concrete. [6]
