What is Foundation?

A foundation volume calculator determines the concrete and material quantities needed for slab, crawl space, or basement foundations. A 1,000 sq ft slab at 4 inches thick requires ~12.3 cubic yards of concrete. Footings must extend below the local frost line to prevent heaving.
