From Sierra: here are the latest photos of our earthbag structure currently being built in B.C, Canada…it is going really well. Frank is the designer and owner.
The fill we are using is on site. We dug down below organic and came up with a great mix of clay, sand and gravel. We added 20% cement to the mix for the foundation levels; most of the structure is 5% cement though, except for door frames and arches (20%).
Because this structure is in a temperate rain forest, we had to go for a cement/lime plaster, its the only thing we found worked. I don’t like the fact that it is not eco-friendly, but we had to compromise somewhere.
We started the project June 16, 2010 worked 5 days a week, 3 people make up the crew. We also had a few volunteers through out the summer, they would work either a few hours or a few days. We ended the summer project in mid Sept, level 20. We are now bagging level 37.
