🧱 Construction Materials
Work out how much material to order before you head to the supplier: concrete in cubic yards or bags, asphalt and gravel in tons, bricks, blocks, tiles, paint, drywall, roofing and more. Densities, bag yields and coverage rates come from manufacturer data sheets and public agencies such as Caltrans and the Brick Industry Association, and you can edit them to match your material. Each calculator includes a waste allowance and rounds discrete items up so you don’t come up short.
