I wonder if you have any natural, mineral based material like perlite or pumice locally available? 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 base under strawbale walls. </div><div><br></div><div>Thanks for sharing so much of your process.
