Slab or pour calculator
Dimensions and volume
Pours and foundations

Slabs, footings, walls

Work through slab, footing, wall, circular column, steps, and post-hole scenarios to get cubic yards, quick yardage checks, and the numbers you need before the truck arrives—without juggling spreadsheets on the tailgate.

Blocks and fill
Rebar or mesh
Masonry and base

Blocks, rebar, gravel

Estimate CMU and block counts, block fill and mortar, rebar grids and wire mesh, plus gravel and asphalt coverage—so base prep and reinforcement stay aligned with your pour plan.

Cost or bags
Project entries
Bags, cost, projects

See it and save it

Convert to bags, sketch costs for quotes, and lean on area and volume shortcuts when you need them—visual diagrams and 3D previews help confirm the shape, while multiple saved calculator entries keep each job organized in one place.
