Why cubic yards?
Ready-mix concrete is sold by the cubic yard; one cubic yard is 27 cubic feet. Every calculator here works in the units you measure on site, converts for you, adds a waste allowance, and shows the order quantity in cubic yards plus the equivalent in pre-mixed bags for smaller jobs.
Pick your pour
Start with the shape that matches your project: a flat slab for patios and floors, a driveway for vehicle areas, or a footing for foundations and load-bearing runs.
What does concrete cost?
