What is a bond pattern (metselverband)?
A bond pattern is the arrangement in which bricks are laid in a wall, so that the vertical joints are staggered and the wall works as a single unit. The bond determines the strength, stability and appearance of the wall. A wall without a bond (joints directly above each other) is structurally weak and can easily crack.
Why is a bond pattern important?
- Load distribution — By staggering the joints, forces are distributed across multiple bricks
- Stability — The bricks interlock, the wall acts as a whole
- Water resistance — Staggered joints prevent water from penetrating straight through the wall
- Aesthetics — The bond determines the appearance of the facade
Common bond patterns
Stretcher bond (running bond)
The simplest bond: all bricks are laid as stretchers (long face visible). Each course is offset by half a brick. Used for half-brick walls (outer leaf of cavity walls) and thin walls.
Random bond
Stretchers and headers are alternated randomly. No fixed pattern, but the joints must still be staggered. Creates a lively, irregular appearance.
English bond
Alternation of stretcher courses and header courses (short face visible). Creates a regular, traditional pattern. Widely used for solid walls.
Cross bond
Variation of English bond, where the headers in successive header courses are staggered. Very strong and decorative.
Flemish bond
Stretchers and headers alternate within the same course. Classic English or Flemish pattern.
Bond patterns for DIY
When building a garden wall, garage or boundary wall:
- Stretcher bond is the simplest and most common for DIY
- Always start with whole bricks at the corners
- Regularly check that the joints are staggered (minimum quarter brick)
- Use a bricklayer’s line for straight courses
