Coverage by depth
Area (sq ft) = cubic feet ÷ (depth in inches ÷ 12). One cubic yard is 27 cubic feet.
| Depth | 1 ton covers (sq ft) | 1 cu yd covers (sq ft) | 1 ton covers (m²) |
|---|---|---|---|
| 1 in | 216 | 324 | 20.1 |
| 2 in | 108 | 162 | 10.0 |
| 3 in | 72 | 108 | 6.7 |
| 4 in | 54 | 81 | 5.0 |
| 6 in | 36 | 54 | 3.3 |
| 8 in | 27 | 40 | 2.5 |
| 12 in | 18 | 27 | 1.7 |
Ton figures use 1.50 tons per cubic yard of crusher run.
Plan for settling
Hello Gravel says to lay 4 to 6 inches of road base for a driveway, compacted in 2-inch lifts. Loose material settles once it is walked on or compacted, so order a little more than the bare volume. Rochester Concrete Products' install guide adds 10% for compaction and uneven ground.
