Will moisture collect behind poly and foam on crawl space walls?
I recently installed a vapor barrier -- 6 mil plastic or maybe 3 mil -- over an entire dirt-floor crawl space and up to the sill plates. We also placed foam board over all exterior walls of the space.
Although this is done to keep moisture out of the space, I worry that moisture will collect behind the foam board and become undetected and create more problems.
