| Depth | Cubic yards | Tons | Tons +10% |
|---|---|---|---|
| 1 in | 2.47 | 3.3 | 3.7 |
| 2 in | 4.94 | 6.7 | 7.3 |
| 3 in | 7.41 | 10.0 | 11.0 |
| 4 in | 9.88 | 13.3 | 14.7 |
Working it out
- 800 sq ft × (3 ÷ 12) ft = 200.0 cubic feet.
- ÷ 27 = 7.41 cubic yards.
- × 1.35 tons per yard = 10.0 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. Expect the weight to fall in the range of 1.3 to 1.5 dry tons per yard.
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.
Good and poor uses for sand
Best suited to:
- Paver and flagstone bedding
- Leveling under above-ground pools (with the right product)
- Filling joints and backfilling pipe
Poor fit 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 20x25 area at 3 inches takes about 6.3 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
