Patti Stouter has expanded and updated her soil testing guide Soil Tests for Earthbag. We’ve added the report to our EarthbagStructures.com and EarthbagBuilding.com websites, where you can find indepth information on every aspect of building with bags.
Using the right soil is very important. After all, earthbag building uses soil as the primary building material, and so you want soil that is strong and stable. Patti walks you through the various types of soil and explains simple low-tech tests for each.
