Elsewhere on this forum I read about an option to chemically treating posts used by builders in East Africa. Tom Rampart wrote, "... we plastic coat the portion of posts to be placed in the ground. We scorch the ground end of a post over a fire - not burn, just scorch. Then we wrap that portion with plastic grocery bags and heat the wrapped end over a fire. If the plastic ignites and burns - too hot. Just want it to melt/shrivel and adhere to the post."
My suggestion - Why not do the same thing to the backsides of shoring boards? Melting the plastic so it is in intimate contact with the wood seems like a great way to prevent condensation between the materials.
