Frequently asked questions
How many tons of gravel for a driveway?
A typical single-car driveway of 50 × 12 ft needs about 10 to 16 tons, depending on depth. Double that for a two-car width.
What's the best gravel for a driveway?
Crushed stone with angular edges, such as #57 stone or crusher run, locks together better than round pea gravel, which tends to shift under tires.
