Hi All-
I wanted to share with you our
experience building 2 small earthbag retaining walls. The link is here:

Last winter the plumbing under the house froze when the furnace went out. (We don't live there full time.) After we fixed all the leaks and put in new insulation and patched the belly board, we decided that the ungodly smell in the house we could not get rid of was the odor from the rodent infestation and leavings in the insulation under the house. (We were right. The furnace ducts were not sealed and the smell came right up through the floor ducts. Getting rid of the insulation and installing spray foam solved the smell.)
The entire
project spanned these smaller ones:
1. Dig out 3 sides of the house (paid work)
2. Remove damaged skirting (DIY)
3. Remove rodent contaminated insulation (paid work - these guys are my heroes)
4. Spray foam insulation in less than 3' of overhead space (paid work)
5. Build new framing for skirting and install Pro-Panel (DIY)
6. Build earthbag retaining walls (DIY)
7. Back fill (paid work)
8. Re-plumb the house interior with pex (paid and DIY)
The parts of the whole plan that remain unfinished are to hook up the well, which is 350' down hill from the house and to finish the scoria bag tank/well house.
This earthbag work was the slowest, dirtiest, most physically demanding work we've ever done. (It didn't help that it was hot. We had to keep chasing shade to work in.) Even putting the burlap-crete coating on was horrifying because the lengths of fabric we used were quite long, and therefore quite heavy. That said, we'd do it all again because the resulting product is wonderfully sturdy and very cheap.
We could not have done it without the work of these people - Owen and Kelly (
