Gravel Calculator

The recommended gravel depth depends on the application:

• Driveways: 4-6 inches (with a compacted base layer)
• Walkways: 2-3 inches
• Patios: 3-4 inches
• Drainage: 6-12 inches (depending on water flow)
• Decorative landscaping: 2-3 inches
• Under pavers: 4-6 inches base + 1 inch sand

Common gravel types and their uses:

• Pea Gravel: Small, rounded stones (3/8") - great for walkways and patios
• Crushed Stone: Angular pieces that compact well - ideal for driveways and bases
• River Rock: Smooth, rounded stones - decorative landscaping and drainage
• Quarry Process (QP): Crushed stone with fines - excellent for compacted bases
• Crushed Granite: Durable and attractive - driveways and pathways
• Limerock: White/gray limestone - bases and fill
• Marble Chips: Decorative white/gray chips - landscaping accents

Gravel weight varies by type. Approximate weights per cubic yard:

• Pea Gravel: ~2,700 lbs (1.35 tons)
• Crushed Stone: ~2,800 lbs (1.4 tons)
• River Rock: ~2,700 lbs (1.35 tons)
• Quarry Process: ~2,900 lbs (1.45 tons)
• Crushed Granite: ~2,600 lbs (1.3 tons)
• Limerock: ~2,800 lbs (1.4 tons)

These weights assume dry material. Wet gravel can weigh 15-20% more.

Important delivery considerations:

• Access: Ensure trucks can reach your property (typically need 10-12 ft wide access)
• Minimum order: Most suppliers require 1-5 ton minimums for delivery
• Delivery fees: Usually $50-150 depending on distance and quantity
• Dump location: Prepare a flat area where gravel can be dumped
• Timing: Order in advance; delivery may take 1-5 business days
• Weight limits: Check if your driveway can handle truck weight (20+ tons loaded)

For small projects under 1 ton, consider picking up bags or bulk from a local supplier.
