How much does a ton of fill sand cover?
Cubic yards = area (sq ft) × depth (in) ÷ 12 ÷ 27. Tons = cubic yards × the material’s density. The calculator then adds the buffer for compaction and spreading and rounds up. Tons use our catalog densities: fill sand 1.3 t/yd³.

Fill sand mistakes to avoid
Fill sand for structural concrete
Use ASTM C33 concrete sand for any structural mix. Fill sand is for grading only.
No lifts on deep fills
Dumping 3 feet of sand and walking away gives you a sinkhole within a year. Place in 6–8 inch lifts.
Pool fill without breaking the shell
A sealed pool shell traps water under fill and creates a long-term sinkhole. Break the bottom up before filling.
Sand against an unprotected foundation
Sand drains, which is good, but install proper drainage at the base of the foundation before backfilling.
