I have a 13 by 25 ft carport with a concrete foundation that I would like to enclose with straw bale, but I am unsure how to secure bales to the foundation while keeping bales dry. Will the bales be fine sitting directly on concrete with rebar driven through into concrete, or could I use concrete blocks to elevate bales off the ground, and still drive the rebar through? The walls will be adequately covered by the roof, so the only spot I am worried about is on the ground. I live in MO where we get 47 inches of rain per year, and the house sits in a semi low spot.
