My house has a sloped crawlspace (where water heater, dehumidifier and furnace/a/c and furnace vents , plumbing are located. It is a concrete block foundation and brick exterior on the main level, then siding on the 2nd story. Timber framing. I want to remodel my home one room at a time by removing the sheet rock and insulation and mixing just hemp hurds with clay (not lime) and water to form the walls/insulation and then put clay plaster as the finish. Is this doable? Is it ok to put the clay/hemp right up against the exterior brick and timber framing? Is there any moisture issues with doing that? Eventually I want to remove the flooring and fill the crawlspace with rock, sand and earth and top with hemp/clay ?? for a finished breathable earthen floor and relocate the water heater and hopefully remove the dehumidifier. Since I have timber framing for the structural aspect of it and I understand hemp is not structural (although the clay should be sturdier than lime) would this be ok??? Is it possible to do this from the inside out? Since it is winter now, I would like to do the interior walls and save any exterior projects for the summer. Thoughts???
Tom Connolly wrote:Thanks for your post, and the helpful replies. Someone mentioned insulation. How does it work to add insulation to the earthbags, on the inside with the soil? I have read of people adding scoria, rice hulls, even styrofoam peanuts. Are these helpful? Do they detract from the strength of the bag? What happens after several years when the rice hulls degrade? Will the empty space they leave still serve as insulation?

Do you plan to have companion plantings around each fruit tree, and use that tree as the anchor for various shrubs and ground covers?
