How to Calculate Sand Requirements for Patios and Pools
Sand is an essential aggregate for construction and hardscaping projects, serving as a flexible bedding layer for interlocking concrete pavers, pool bottom leveling, and lawn topdressing.
Standard Sand Depths by Project Application
| Application | Standard Depth | Recommended Sand Grade |
|---|---|---|
| Paver Bedding Layer | 1.0 inch (Exact) | Coarse Concrete Sand (ASTM C33) |
| Above-Ground Pool Base | 2.0 inches | Washed Masonry Sand (fine & rock-free) |
| Children's Sandbox | 6.0 to 8.0 inches | Certified Safe Play Sand (non-toxic) |
| Lawn Leveling & Aeration Topdress | 0.25 to 0.50 inches | Fine Mason Sand or 70/30 Sand-Soil Mix |
Frequently Asked Questions
How deep should sand be for paver patios and walkways?
A standard interlocking paver patio requires 1 inch of sharp bedding sand (coarse concrete sand) installed directly over a compacted 4-to-6-inch gravel sub-base.
How much does a cubic yard of sand weigh?
One cubic yard of dry masonry or play sand weighs approximately 2,600 to 2,700 lbs (1.3 to 1.35 tons). Wet or saturated sand can weigh up to 3,000 lbs (1.5 tons) per cubic yard.
How many 50-lb bags of sand make a cubic yard?
Since one cubic yard of sand weighs roughly 2,700 lbs: 2,700 / 50 = 54 fifty-pound bags of sand per cubic yard.
How much sand do I need under an above-ground pool?
Above-ground pool manufacturers generally recommend a 2-inch layer of masonry sand across the entire pool footprint to protect the vinyl liner from punctures. For a 15-foot round pool: (3.14 x 7.5^2 x 2) / 324 = 1.09 cubic yards of sand.
