that is the robustness and repairability of the system in the event of failures, which should be taken into account at the design and construction stage. Certainly as far as the flood or for that matter the snow is concerned, bales should be raised off the
ground above the 1 to 50 or 1 to 100 year ARI.<o:p></o:p></span></p>

If so, you might want to check it out. Just a thought. We used a cavity brick wall filled with pumice-like coal slag as an insulated wall at the base of strawbale walls in northern China. Not perfect, but locally available and a good moisture resistant wall
