FAQs
- Does this calculator size the slab?
- No: it only estimates m³. Depth, rebar and strength are signed by a qualified professional.
- How much do I order from the plant?
- The volume with waste, rounded up (e.g. 3.21 → 3.5 m³).
- Pump or direct pour?
- If the truck can't reach, add pumping as a line item. The volume doesn't change.
