Brickwork masonry is produced when a bricklayer uses bricks and mortar to build up structures such as walls, bridges and chimneys. Brickwork is also used to finish openings such as doors or windows in buildings made of other materials. Where the bricks are to remain fully visible, as opposed to being covered up by plaster or stucco, this is known as face-work.
Flemish bond, also known as Dutch bond, has historically always been considered the most decorative bond, and for this reason was used extensively for dwellings until the adoption of the cavity wall. It is created by alternately laying headers and stretchers in a single course.
Monk bond is a variant of Flemish bond, with two stretchers between the headers in each row, and the headers centred over the join between the two stretchers in the row below.
Scottish bond has one row of headers to five of stretchers.
Rat-trap bond, also known as Chinese bond, is a type of garden wall bond in which the stretchers and headers are laid on their sides, with the base of the stretcher facing outwards. This gives a wall with an internal cavity bridged by the headers, hence the name.
