How to Use This Calculator

Enter Wall Length, Wall Height, and Wall Thickness (in) to define the wall volume.
Set Lift Height (in) — typically 6-8 inches per compacted lift.
Enter Form Length (ft) to calculate the number of form placements needed.
Review Wall Volume (cu ft) and Loose Soil (cu yd) — rammed earth requires about 3:1 loose-to-compacted volume.
Use form placement count and lift count to schedule crew labor and form-stripping cycles.

How the result changes with Wall length (ft)

Identify Input Parameters
4 parameters
Wall length (ft) = 20, Wall height (ft) = 10, Wall thickness (in) = 18, Lift height (in) = 6 = 5 input(s) provided
Calculate Wall volume
Wall volume = wallLength * wallHeight * (wallThicknessIn / 12)
300 = 300
Calculate Loose soil
Loose soil = round((wallVolCuFt * 1.4) / 27 * 100) / 100
15.56 = 15.56
Calculate Form placements
Form placements = formSets * lifts
60 = 60
