Frequently Asked Questions
How deep should gravel be?
Walkways and garden beds: 2-3 inches. Driveways: 4-6 inches (with proper base). Drainage areas: 3-4 inches. Deeper layers provide better coverage and longevity.
How many tons are in a cubic yard?
Most gravel weighs about 1.4 tons per cubic yard. River rock is lighter (~1.2 tons), while granite is heavier (~1.5 tons). Verify with your supplier for exact weights.
Should I use landscape fabric?
Yes, install landscape fabric before adding rock/gravel to prevent weed growth and keep rock from sinking into soil. This also makes future removal easier.
