How much do you need?
At the 4 inch depth we recommend for gravel / limestone (2a, 2b, 1b, 3b), one cubic yard covers about 81 square feet. Use 4 inches for a driveway top-up and 6 to 8 inches (compacted in lifts) for a new base. 2A modified compacts tighter than clean stone.
A cubic yard weighs roughly 1.45 tons loose, so we quote both yards and tons — yards tell you how much space it fills, tons tell you what your truck has to carry.
| Depth | One cubic yard covers |
|---|---|
| 2" | about 162 sq ft |
| 3" | about 108 sq ft |
| 4" (recommended) | about 81 sq ft |
| 6" | about 54 sq ft |
Measure the area you are covering, pick your depth, and the material calculator will work out the yards for you. Not sure what depth you need? Call us on 724-650-8418 and describe the job.
