Strip Foundation Concrete Volume Calculator
Calculate concrete volume with ordering allowance for continuous strip footings from total length, width and depth.
Formula
Planning estimate. Check product specifications and local requirements before purchasing.
Worked example: Strip Foundation Calculator
Measurements in this example
| Total foundation length | 42 m |
|---|---|
| Foundation width | 0.5 m |
| Concrete depth | 0.8 m |
| Waste allowance | 7 % |
Calculated quantities
| Volume | 16.8 m³ |
|---|---|
| Total concrete volume | 17.98 m³ |
What to check
This calculation uses: Total foundation length, Foundation width, Concrete depth, Waste allowance. It returns: Volume, Total concrete volume.
Use dimensions from the structural drawings and check excavation against them before concrete or steel is ordered.
The ordering figure excludes pump priming, severe overbreak and unrecorded level changes unless they are included in the inputs.
Foundation size, reinforcement, cover, joints and bearing conditions are structural decisions that require a qualified design.
Use the units beside each field. The values in the worked example are starting inputs; replace them with your measurements and the specifications of your material.
