Worked example: 1 inch of bedding sand
| Step | Math | Result |
|---|---|---|
| Area | 12 ft × 12 ft | 144 sq ft |
| Volume at 1 in | 144 × 1 ÷ 12 | 12.0 ft³ |
| Add 10% extra | 12.0 × 1.10 | 13.2 ft³ |
| Cubic yards | 13.2 ÷ 27 | 0.49 yd³ |
| Tons | 0.49 × 1.35 | 0.66 tons |
| 0.5 ft³ bags | 13.2 ÷ 0.5 | 27 bags |
Sand by depth
| Depth | Cubic yards (+10%) | Tons | Bulk order (tons) | Delivered | 0.5 ft³ bags | Bag cost |
|---|---|---|---|---|---|---|
| 1 in | 0.49 | 0.66 | 1.0 | $140 | 27 | $135 |
| 1.5 in | 0.73 | 0.99 | 1.0 | $140 | 40 | $200 |
| 2 in | 0.98 | 1.32 | 1.5 | $160 | 53 | $265 |
At 1 inch, bags are cheaper: $135 in bags versus $140 delivered. Use coarse concrete sand for bedding, screeded level to about 1 inch (not thicker than 1.5 in). Polymeric or fine joint sand is a separate small purchase.
Prices used: 0.5 ft³ sand bag $5.00; bulk sand $40/ton plus $100 delivery (1 ton minimum).
