Sam, if i understand your post you think that underground/earth bermed structures are harder to fix than above ground/non earth bermed structures. i agree. I met
Mike Oehler in 1981 or 2 at a summer gathering outside Rapid
City S.D. He was one of many people peddling their
books, crafts, etc. at the AIM (American Indian Movement) sponsored week. I remember pickup trucks running on alcohol, lots of
solar workshops and books, good music including Jackson Browne and Bonnie Rait. Oehler was barefoot and wild even compared with the rest of us who were living on the fringes. He also came across as honest, unassuming, very self-confident and he challenged people to get out and "do it". However, his structure was almost completely his own with little to no input from others and he did appear a bit defensive when people challenged him about how he built
underground (back then he called his house an underground house). Nothing gets my attention and respect like someone who tries and shares with others, especially if they include the mistakes! I think the process of sharing information through websites like this one will accelerate our learning. Doing what he did, then writing a book on it and then defending it seemed like skipping important steps in the learning process which should include learning from others and talking about the failures as well as successes. So I am glad to see Oehler's work cited and incorporated into this group. Having said that I am hesitant to build underground in central Illinois mostly because of the heavy clay and termites on our
land. I do plan on building some out buildings and a bermed
greenhouse using EPDM. I'll keep you all posted on my projects.
Don't forget the people who are working on underground/bermed structures on Paul's land are in Montana which is drier than where most of us live and has no termites.
