Bricks for an 8 × 2 m wall
A wall about this high is a garden boundary or privacy wall. A freestanding wall over about 1 m needs piers or an engineer's advice, and walls next to a highway or over 2 m may need planning permission. This wall is 16 m². Counts are for standard bricks (215 × 102.5 × 65 mm) with 10 mm joints, and the mortar is a 1:4 cement to building sand mix.
| Wall thickness | Bricks | Packs of 500 | Building sand (tonnes) | Cement (25 kg bags) |
|---|---|---|---|---|
| Single skin (half-brick, 102.5 mm) | 1,008 | 2.0 | 0.90 | 9 |
| One brick thick (215 mm) | 2,016 | 4.0 | 1.79 | 17 |
How much to allow for waste
Cuts and breakage use up bricks. Use 5% for a plain straight wall, 10% for most jobs, and 15% where there are piers, corners or patterned work (single skin).
| Waste | Bricks | Packs of 500 | Building sand (tonnes) | Cement (25 kg bags) |
|---|---|---|---|---|
| 0% | 960 | 1.9 | 0.85 | 8 |
| 5% | 1,008 | 2.0 | 0.90 | 9 |
| 10% | 1,056 | 2.1 | 0.94 | 9 |
| 15% | 1,104 | 2.2 | 0.98 | 9 |
