ConCalc - Concrete Calculator

Know exactly how much concrete to order. ConCalc works out the volume for the shapes you actually pour, in cubic yards or cubic meters, and adds them into one running total. Built for contractors and for anyone doing it themselves. TWELVE SHAPES Slabs — rectangular, round, semicircle, or straight from an area. Footings, walls, curbs, curbs with gutter, square and round columns, steps, and drainage channels. Each one asks only for the dimensions it needs, with a diagram showing what you're measuring. ONE JOB, ONE TOTAL Save calculations into a named project and keep a job on file for as long as it runs. Subtract a cutout or an opening from the total. Add a waste allowance and see it carried through to the figure you order from. WHAT TO ORDER, AND WHAT IT COSTS Buying ready-mix? Price it by volume. Buying bags? Choose from nine bag sizes, 40 lb through 40 kg, and get the bag count and the cost together. TAKE IT OFF THE PHONE Export a project as a CSV and send it wherever it needs to go — email, messages, or a spreadsheet.
