💡 Pro Tips
- Driveways: 4–6" depth with compacted base
- Walkways: 2–3" depth is usually sufficient
- French drains: Fill trench with 3/4" gravel
- Gravel weighs about 1.4 tons per cubic yard (varies by type)
- Pea gravel is lighter (~1.3 tons/yd³), crushed stone heavier (~1.5 tons/yd³)
- Order 10–15% extra — gravel always seems to disappear
