Concrete shapes
Estimate slabs, circles, columns, walls, strip and pad footings, post holes, stairs, curbs, hollow rings, and measured areas.
Concrete Calc takes you from field dimensions to a reviewed order quantity, then keeps every slab, footing, wall, reinforcement item, mix, and pour detail organized in one project.
Every estimate separates geometric volume from ordering allowance, preserves your measurement system, and presents assumptions for review before work is saved or shared.
Estimate slabs, circles, columns, walls, strip and pad footings, post holes, stairs, curbs, hollow rings, and measured areas.
Calculate rebar grids, wire mesh, formwork, block wall, block fill, mortar, aggregate base, mix ratios, bags, trucks, and cost comparisons.
Changed inputs are highlighted, and every estimate must pass a field-by-field acknowledgement before it can be saved or shared.
Combine concrete, reinforcement, masonry, and material calculations in one job, then duplicate, reorder, or revise items as the scope changes.
Group concrete by mix and date, record strength and slump, and prepare supplier-ready schedule, placement, access, safety, and washout details.
Create branded reports containing project totals, measurements, results, assumptions, pour specifications, and page-level verification reminders.
These screenshots come directly from the Concrete Calc iPhone build and show the estimating, review, project, and supplier workflows.
