はじめに

Concrete Footing Calculator — Volume of concrete needed for a strip footing. Enter Length (m), Width (m), Depth (m), Waste (%) to get an instant, accurate result.

計算式

Volume = length × width × depth of the footing trench, plus a waste percentage allowance, converted to cubic yards.

ステップごとの説明

Enter the Length (m).
Enter the Width (m).
Enter the Depth (m).
Enter the Waste (%).
Click Calculate to see your result instantly.

実例

Example: With Length (m) = 10, Width (m) = 0.5, Depth (m) = 0.3, Waste (%) = 5, the Concrete Footing Calculator gives Volume M3: 1.575, Volume Without Waste M3: 1.5, Volume Cubic Yards: 2.06.

よくある質問

How deep should a footing be?

Depth depends on local frost line and soil bearing capacity — check your local building code or a structural engineer before pouring.

Does this include the stem wall above the footing?

No, this calculates the footing only — use the Concrete Wall or Foundation calculator separately for the wall above it.

What inputs does the Concrete Footing Calculator need?

You'll need to provide: Length (m), Width (m), Depth (m), Waste (%). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Concrete Footing Calculator?

The Concrete Footing Calculator applies the formula exactly as calculated — Volume = length × width × depth of the footing trench, plus a waste percentage allowance, converted to cubic yards. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Concrete Footing Calculator free to use?

Yes, the Concrete Footing Calculator is completely free, requires no signup, and runs instantly in your browser.
