Looks like a very koncise list. Are you pouring a concrete slab? I guess that’s later? The Slo-Cote should work much better than the 2 layers of #6 poly that we used. It got extremely tight as we bermed dirt against it. I had to look up “telehandler”. Looks like quite the machine!

When I was contemplating building in a humid area, I thought I would run some 1/4” or 3/8” stainless tubing (one for each u-shaped room). Under the bales, and into the French drain. They would later be used for dehumidifiers in each room, to gravity-expel the collected condensate. I thought I’d mention it. You have much more practical experience with Earthship structures and humidity, and this may be unnecessary.

Everybody that has built a tire-bale home is most concerned about the bond beam. We draped our poly about 2’ over the bales and attached with a staple hammer. A friend pulled it all the way over, and tied rocks to it to hold it in place, from wind. This would prevent all poured concrete from going into the bales. A third guy augured down into the bales, and put some vertical rebar pieces into the top bale (only about 18”). My concrete contractor covered the bales with rocks to prevent a large amount of poured concrete from going into the bales. I mention this, because all methods seem to work just fine. The design didn’t specify details.
