[Cob] Adapting Earthbag stemwallJennifer Roberts smurf_goddess at hotmail.com

I am going to start building this summer on a foundation created by the previous owners of my land, a 17x17 octagonal concrete pad with an earthbag stemwall. Local people use earthbags a lot for strawbale construction (which this was intended for) and use masonry to coat the outside of the bags instead of plaster to prevent wicking of moisture. I also wondered if I could create a smaller rock layer on top of the earthbags to give the cob on the south side something to stick to. Does anyone have experience with masonry and earthbags? Also, does anyone have experience with importing earth to make their cob? I have pure desert sand (beach-like) but considered calling pool installers, foundations diggers, in nearby areas with clay soil to get this for free. It's a minimum 60 mile drive to perform a soil test- any other ideas? Though I love cob, I am thinking it may not be realistic considering my soil type and climate. Thanks!
