CALCULATING YOUR TOTAL CUBIC YARDS / TONS: Use the below calculators to determine the total cubic yards / tons with the corresponding depth.

DIRECTIONS: Enter the width of the area you are working with, then enter the length of the area. The calculator will automatically render what you will need in cubic yard as well as a tonnage equivalent at different depths (thickness). Consult our staff for the best depth for your particular project.

PLEASE NOTE: This is an tool that gives an approximate answer, some stones and aggregates are lighter than others and may alter the totals. This calculator is based on a Drain Rock (loose rock) density of 2,835 lbs per cubic yard. For Base Rock (compacted rock), multiply your totals by 1.4 for a density of 4,000 lbs per cubic foot. Check with our staff for all final quotes.
