Awhile ago, I wrote to you asking if you had any recommendations for stabilizing our 14′ (inner diameter) scoria dome tank house which had started to fail as a result of the bags breaking down. I wanted to give you an update.
We paid a crew last November to shotcrete it inside and out, and it is performing very well. I just wish I knew whether it was the mass of concrete or the insulation of the bags. Probably a combo. I am interested to see how it performs once the mass has heated up a bit this summer.
Our final stop on the tour of Asher Gelbart’s off-grid homestead was a work in progress of incorporating an old Airstream trailer into a larger architectural project. Asher is holding up a model of this concept, which would not only feature a spiral roof covering most of it, but also earthbag domes.
