Common Mistakes to Avoid
❌ Not adding enough depth
Gravel driveways need 4-6 inches of depth. Thin layers rut and displace quickly.
❌ Forgetting compaction
Gravel compacts 10-20% after settling. Deliver and measure slightly more than calculated.
Frequently Asked Questions
Gravel vs crushed stone?
Crushed stone: better drainage, more stable for driveways. Pea gravel: decorative, less stable. 3/4-inch crushed stone is most versatile.
How many tons in a cubic yard?
Gravel: ~1.4 tons. Crushed stone: ~1.5 tons. Sand: ~1.35 tons. Weight varies by material.
Driveway depth?
New driveway: 4-6 inches minimum. Well-compacted base: 4 inches surface gravel on top of 6 inch base layer.
