| Depth | Cubic yards | Tons | Tons +10% |
|---|---|---|---|
| 1 in | 0.46 | 0.6 | 0.7 |
| 2 in | 0.93 | 1.2 | 1.4 |
| 3 in | 1.39 | 1.9 | 2.1 |
| 4 in | 1.85 | 2.5 | 2.8 |
Working it out
- 150 sq ft × (3 ÷ 12) ft = 37.5 cubic feet.
- ÷ 27 = 1.39 cubic yards.
- × 1.35 tons per yard = 1.9 tons.
About sand
For paver bedding, concrete sand (coarse, washed) is the usual pick. Mason sand is finer and used in mortar and play areas. Most suppliers will quote 1.3 to 1.5 dry tons per yard for this material.
Before the truck comes
- Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
- Add a margin. About 10 percent covers compaction and low spots.
- Bulk or bags. Bulk delivery is the practical choice here.
- Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.
Use the volume and tonnage calculator for any other size.
Where sand fits
Works well for:
- Paver and flagstone bedding
- Leveling under above-ground pools (with the right product)
- Filling joints and backfilling pipe
Think twice for:
- Driveway bases, since sand shifts under load
- Steep areas exposed to runoff
- Thick layers under pavers, which settle unevenly
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of sand (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 8x16 area at 4 inches takes about 2.1 tons.
- Weight used here: about 1.35 tons per cubic yard.
Where estimates go wrong
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
