Foundation Wall Calculator

Concrete volume for a foundation wall by perimeter.

Introduction

Foundation Wall Calculator — Concrete volume for a foundation wall by perimeter. Enter Perimeter (m), Height (m), Thickness (m), Waste (%) to get an instant, accurate result.

Formula

Volume = perimeter × height × thickness of the foundation wall, plus a waste percentage allowance, converted to cubic yards.

Step-by-step

  1. Enter the Perimeter (m).
  2. Enter the Height (m).
  3. Enter the Thickness (m).
  4. Enter the Waste (%).
  5. Click Calculate to see your result instantly.

Real-world example

Example: With Perimeter (m) = 40, Height (m) = 2.4, Thickness (m) = 0.2, Waste (%) = 5, the Foundation Wall Calculator gives Volume M3: 20.16, Volume Without Waste M3: 19.2, Volume Cubic Yards: 26.3683.

Frequently Asked Questions

Should I use the building perimeter or the footing perimeter?
Use the actual centerline length of the foundation wall you are pouring for the most accurate volume.
Is footing volume included here?
No, this calculates the foundation wall only — use the Concrete Footing calculator separately for footings beneath it.
What inputs does the Foundation Wall Calculator need?
You'll need to provide: Perimeter (m), Height (m), Thickness (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 Foundation Wall Calculator?
The Foundation Wall Calculator applies the formula exactly as calculated — Volume = perimeter × height × thickness of the foundation wall, 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 Foundation Wall Calculator free to use?
Yes, the Foundation Wall Calculator is completely free, requires no signup, and runs instantly in your browser.
