Frequently Asked Questions
How thick should a gravel driveway be?
8-12 inches total for cars. 12-16 inches for trucks and heavy vehicles. Build in layers - thicker layers do not compact properly. Sub-base 4-6 inches, base 3-4 inches, top 2-4 inches. Compact each layer with a plate compactor before adding the next.
Best stone size for gravel driveway?
Top layer: #57 stone (3/4 inch) or 411 (1 inch). Base layer: #2 stone (1.5-2.5 inch). Sub-base: #3 stone (1.5-2.5 inch). The larger stones at the bottom drain better; finer top compacts smoother for driving comfort.
How long does a gravel driveway last?
30+ years with proper installation (geotextile underlayment, three layers, proper crown). Add a top dressing every 4-7 years to replace surface gravel lost to erosion and tire wear. Costs about $200-500 per refresh on a typical residential driveway.
