FAQ
How much gravel do I need for a 100-foot driveway?
At 10 feet wide and 4 inches deep, about 15 tons — widen the driveway or add a second base layer for heavier traffic, which increases the total accordingly.
Should I compact gravel in layers on a long driveway?
Yes, adding and compacting gravel in 2-3 inch lifts prevents ruts and settling far better than dumping the full depth at once, especially on a driveway this long.
How often does a gravel driveway need more material?
Plan on topping off with fresh gravel every 1-3 years depending on traffic and drainage, since rain and vehicles gradually displace the surface layer.
Accuracy and limitations
- Estimates assume standard, average conditions — local rules, pricing, and materials vary.
- Results are rounded for readability; add a buffer before ordering, booking, or committing.
- Double-check anything with a real cost attached against a local quote.
