Footing intentConcrete footing volume calculator
Use this page for strip footings, trench fills, and foundation runs where length matters more than width. It gives a quick route from dimensions to cubic meters.
Best for
- Strip footings
- Trench fills
- Foundation runs
Worked example
A 20 m footing, 0.6 m wide and 0.3 m deep
Footings are straightforward if you keep the run length, width, and depth consistent.
Example
20 m × 0.6 m × 0.3 m = 3.6 m3. With 5 percent waste, the adjusted order volume is 3.78 m3.
Formula
Volume = length × width × depth
Adjusted volume = volume × (1 + waste / 100)
How to use it
When to use this page
Run length
Measure the footing in segments if the depth or width changes along the run.
Width and depth
Use the real concrete section, not the wall size above it.
Waste factor
A small allowance covers spill, uneven trench bottoms, and formwork variation.
