I need to get a small earth wall up fast. It will be the back wall of a solar greenhouse
. If I can get this wall and some of the wooden framework up and covered with building plastic, I will be able to work on the glazing and interior all winter. Colorado winters can be very cold and snowy, but only for a few days here and there. Most days it gets up above forty degrees, and snow rarely lasts more then a week on the ground.
So, I need an earth wall which can take a some light frosts and go up fast. What would be best? Earthbag, cob
, slipform rammed earth, or slipform poured stabilized adobe? This wall also needs to be able to take greenhouse
conditions (under a layer of lime plaster.)
Earthbag would need buttresses. Rammed earth needs forms. Cob
can go slow and mold in a damp cold period. I am not sure on the process for slipform adobe.
CEBs are out of the question due to lack of money for a machine.
