Earthbag Foundation for Floor System — 4 Comments

    • Most soils will compress under the weight of a full sized earthbag wall. Settling will cause the plaster crack apart, etc. So obviously strong foundations are critical.

  1. In this application the bags are internal walls. And, as you can see in the photo they’re resting on a bed of gravel. So this is not a typical case. Most earthbag buildings will benefit from a rubble trench foundation. Earthbag walls are very heavy. Rubble trenches are great for carrying heavy loads like this.

  2. Brilliant! Why didn’t I think of that? There’s no need to dig a trench for extra drainage really, is there? The gravel will simply let the water wash through, and the bags are more than strong enough by themselves, without being embedded in the ground. Thanks for sharing!
