“The back mass wall is up to the 7th course of bags and another course of foam insulation is about to start. In the video I show how the geotextile is woven through the mass wall making it monolithic. This is an invention by Howard Switzer (the Architect on this project) and he calls it “continuous buttress earthbag walls”. This design eliminates the need for poured concrete buttresses and battering the walls (leaning them back) and allows for a cleaner looking straight walled interior. We have had 300% the normal rainfall this summer in TN and this has resulted in much less progess than was anticipated.

What Jake and his architect have done is show the refined process on an actual project. So yes, this is a first of its kind project and I applaud their efforts, especially since there’s a great deal of interest in building earthship type designs more efficiently. This process could be engineered to meet code for earthbag walls. Maybe your architect did the calcs. If so then hats off to him and that would be a breakthrough versus my article which just sketched out the basic concept based on how highway retaining walls are built.
Production rate using his earthbag tube filling machine: On a good day me (42) and my 67 year old dad can get 70′ of bag wall done. I have a $5,000 late 60s backhoe that I use to put the dirt right behind the wall so we can shovel it right in the tube. This reduces the manual labor.
