Learn how to make a low-cost, low-impact, durable earthbag foundation for any type of building, from small shed to full-sized home!
Earthbag building is a low-tech solution to making foundations (or entire buildings) using basic materials and simple tools. Drawing on the age-old technique of rammed earth building, earthbag uses woven sack material to provide a ready-made, leave-in-place formwork for containing rammed earth mixtures.
Earthbag construction can often use site soils as the basis for the rammed earth mix, or local gravel, sand, clay (or other binders) can be used.
In this workshop you will learn how to source the materials for earthbag building, how to test soils for suitability, how to create a suitable rammed earth mix, and how to layout, fill and tamp earthbags to create a stable, level foundation structure. The workshop will also examine how earthbag can be mated with a variety of different conventionl and alternative wall systems. Engineering and code approvals will also be covered.
At the end of this workshop, you will be ready to construct your own earthbag foundation for your own project!
