Field notes
The concrete workflow offers slab, footing, column, and stair shapes, with unit selectors, an adjustable waste allowance, and optional ready-mix or bag prices. For a 10-by-10-foot patio at 4 inches thick, the page works through 33.3 cubic feet, adds 10% waste, then gives 1.36 cubic yards or 62 80-pound bags. The related stone calculator lists material options including crusher run, pea gravel, and stone dust.
