Frost damage can occur as cracks, stone splinters and swelling of the material. When water freezes, the volume of water increases by 9 %. [citation needed] When the volumetric moisture content exceeds 91 %, then the volume increase of water in the pores of the material caused by freezing cannot be absorbed by sufficient empty pores. This causes ...

Some contractors bring the mortar to the very edge, flush with the face of the brick. Others leave it recessed back to allow water to shed off the building. There are three types of recessed mortar: bucket handle, weatherstruck, and simply recessed. The bucket handle is when the mortar is in a curve shape away from the face of the brick.
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').
Air brick: A brick with perforations to allow the passage of air through a wall. Usually used to permit the ventilation of underfloor areas. Bat: A cut brick. A quarter bat is one-quarter the length of a stretcher. A half-bat is one-half. [1] Bullnose: Rounded edges are useful for window sills, and capping on low and freestanding walls.
Painting brick has long been seen as a bit of a faux pas—many experts say paint ruins brick by compromising its natural texture and porosity—which is where limewash comes in.
A metal damp proof course (DPC) between the stone foundation and brick wall. Damp proofing in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences.
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]
