How it works
- Enter slab or concrete dimensions in imperial or metric units.
- Set reinforcement, mesh or mix inputs for your job.
- Review quantities against drawings, then save or export when available.
Material takeoffs are estimates. Confirm structural requirements, reinforcement schedules, cover, laps, waste, mix design and site measurements with project drawings and the responsible professional.

Questions
- Is SlabKit a structural design approval?
- No. The app offers takeoffs and calculation aids. A qualified professional must confirm structural design and local requirements.
- Does it support both unit systems?
- Yes. The app provides imperial and metric inputs; verify units on every result and exported sheet.
- Where are projects stored?
- Projects are stored in the app on the device. A PDF leaves the app only when you choose to share or save it.
