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.
