How this tool works
Results are instant and based on the values you provide. Validate outputs against drawings, specifications, and project controls before procurement or construction.
Assumptions
- All dimensions are entered in metres.
- Result excludes waste allowance and overbreak.
Practical notes
- Add 5–10% waste depending on pump setup and finish tolerance.
- For irregular pours, break the shape into multiple rectangles and total the volume.
Example calculation
Example: 12m × 4m × 0.15m = 7.2 m³ of concrete.
