SlabMate: Concrete Calculator

Calculate concrete volume, bags, mix, waste and cost with a visual pour preview. Works offline, so it is ready whenever you are on site.

SlabMate gives tradespeople and DIY users clear concrete estimates without spreadsheets or guesswork.

Choose the type of pour, enter the dimensions, and see the required volume, litres, bag count, waste allowance, estimated weight and cost. An isometric preview helps you catch dimension mistakes before you order or mix.

Use it for slabs, shed bases, paths, post holes, pads, footings, columns, steps and ring bases. The calculator works offline and remains free to use.

SlabMate Premium adds saved jobs, editing, duplication, search, custom material profiles and reusable mix settings.

The yearly plan is an auto-renewing subscription unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in Apple Account > Subscriptions. The lifetime option is a one-time purchase and does not renew.
