ClarityHow to use this tool
- Enter total footing length, footing width, footing thickness, waste allowance.
- Select Calculate to view the result.
- Check the method and assumptions below before using the result.
The method, explained
Volume = total length × width × thickness × (1 + waste/100).
Using total footing length = 30 m, footing width = 0.5 m, footing thickness = 0.25 m, waste allowance = 10 %, the result is 4.125 m³. Change these example inputs to match your task; use the method above to check each step.
What to keep in mind
Sizing is supplied by the user; no soil or structural adequacy is assessed. A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.
Common questions
Which inputs does this calculation need?
Estimate concrete volume along a continuous rectangular footing. Enter total footing length in m, footing width in m, footing thickness in m, waste allowance in %. The filled example is editable and is not a saved personal record.
