Based on 100 lb per cubic foot, or 1.35 tons per cubic yard (Penn State Extension).
Penn State Extension recommends starting at 2 inches and never exceeding 6 inches. Depths above 4 inches are usually specified for blended footing, not plain sand.
Six inches is the maximum, not a target. Penn State Extension states that sand deeper than 6 inches is stressful to horse tendons.
Do not forget the base.
Compacted crushed aggregate 4 to 6 inches is the standard extension recommendation, at 1 to 2 percent slope for drainage.
Site caution: NRCS AEN-4 gives 6 to 25 inches depending on subgrade strength, so soft or wet sites need more.
Common questions
Before you call the supplier.
- How much sand do I need for a horse arena?
- Multiply the arena length by width, multiply by the footing depth in feet, then divide by 27 for cubic yards. This calculator also estimates tons using 100 pounds per cubic foot for plain sand, 90 for blended footing, and lets you include a waste factor.
- How deep should arena sand be?
- Penn State Extension recommends starting at 2 inches and never exceeding 6 inches. Depths above 4 inches are usually specified for blended footing rather than plain sand.
- How many tons is a cubic yard of sand?
- For plain sand this estimate uses 1.35 tons per cubic yard, based on 100 pounds per cubic foot. Blended footing is lighter, so the calculator uses 90 pounds per cubic foot, or about 1.22 tons per cubic yard. Confirm the actual mix weight with your supplier.
