How to use the Retaining Wall Quantity Calculator
- Enter the wall length.
- Enter the stem height and thickness.
- Enter the base width and thickness, then read both volumes and the total.
Questions
Is the stem on top of the base?
The volumes are calculated separately and added. Overlap is not removed, so keep the stem height as the stem only.
Is the wall designed?
No. This is the concrete quantity of the two rectangles you describe.
