Frequently Asked Questions
Q: How do I calculate how much gravel I need?
Volume (cubic yards) = Length (ft) × Width (ft) × Depth (inches) ÷ 324. Then multiply by 1.4 to convert to tons (gravel weighs about 1.4 tons per cubic yard).
Q: How deep should gravel be for a driveway?
For a gravel driveway, use 4 to 6 inches of depth. For foot paths and landscaping, 2 to 3 inches is sufficient.
Q: How much does a ton of gravel cost?
Gravel typically costs $10 to $50 per ton depending on the type (crushed stone, pea gravel, river rock) and your location.
