English Bond


This bond is made up of alternating courses of stretchers and headers. This produces a solid wall that is a full brick in depth. English bond is fairly easy to lay and is the strongest bond for a one-brick-thick wall. If only one face of an English bond wall is exposed, one quarter of the bricks are not visible, and hence may be of low visual quality.

Quarter bond is formed by a part (or bat) brick known as a 'queen closer'. This is a brick cut in half length ways, generally along the frog and laid in the course next to the corner brick or 'quoin header'. Whereas the stretcher or half bond is formed by successive courses being staggered by half a brick, the Flemish and English bonds are now staggered by a quarter, resulting in a stronger bond (the constructional self-weight being distributed over a greater area). This bond, as well as Flemish bond, does not necessarily have to be one brick thick, they can be built using 'snap headers' ie. headers cut to half their length, which give a full brick appearance. They are often used in cavity walls when matching existing solid wall patterns.
