Estimate the volume of soil to be excavated for foundations or trenches. Calculates cubic yards needed for removal or fill ordering.
Soil 'swells' when dug up. Clay can expand 20-40%, while sand expands 10-15%. You'll need more trucks to haul it away than the hole volume suggests.
Construction materials like soil, concrete, and mulch are universally sold and transported by the Cubic Yard in the US.
Add expansion factor for loose soil.
