What is Cross Bond (Brickwork)?
Cross bond is a masonry bond in which the bricks in successive courses are always staggered by half a brick, so that the vertical joints of one course fall over the middle of the bricks in the course above and below. This creates a diamond pattern in the wall and gives high strength because there are no continuous vertical joints.
How Does Cross Bond Work?
In cross bond the brick courses are laid so that:
- Odd courses start with a whole brick
- Even courses start with a half brick (closer)
- The perpend joints (vertical joints) never fall directly above each other
This produces a strong, even pattern that resembles a grid.
Cross Bond vs. Other Bonds
| Bond | Stagger | Feature |
|---|---|---|
| Stretcher bond | Half brick per course | Thin wall (half-brick thick), most commonly used |
| Cross bond | Half brick, but with specific perpend pattern | Strong, regular pattern |
| Stack bond | No stagger (dangerous!) | Weak — never use |
| Flemish bond | Alternating stretcher and header in each course | Decorative and strong |
| English bond | Alternating courses of stretchers and headers | Thick, strong walls |
Applications of Cross Bond
- Garden walls
- Fence foundations
- Load-bearing partition walls (non-cavity)
- Decorative exterior walls
- Historic restorations
Laying Cross Bond — Step by Step
- First course: lay whole bricks from left to right
- Second course: start with a half brick (closer), then whole bricks
- Third course: same as first course
- Repeat the pattern: the stagger must be maintained consistently
- Corners: require special attention — use three-quarter bricks to keep the bond correct
Cross Bond for a Garden Wall
For a free-standing garden wall, cross bond is a good choice:
- Half-brick wall (10–11 cm thick): suitable up to approx. 1 m high
- Single-brick wall (21–22 cm thick): up to approx. 1.80 m — a two-brick cross bond can be used here
- Always use a water-shedding layer (coping or soldier course) at the top
