Frequently Asked Questions
How much sand do I need?
Area × depth in feet gives cubic feet. 100 sq ft at 2 inches deep is 16.67 cu ft, or about 0.62 cubic yards.
What density should I use?
Dry sand weighs about 90 to 100 lb per cubic foot and wet sand up to 120 or more. The weight tells you whether a pickup or trailer can carry it safely.
Should I buy extra?
Yes, about 10% more, because sand compacts when tamped and spreading is never perfectly even. Suppliers usually sell by the cubic yard or ton.
