I have a fieldstone basement covered with 15mil poly that directs any water in to my french drain. This part of the system works well and has prevented any incoming water from finding its way on to the floor, but now I find myself in a strange situation where I really don't know what to do for insulation so that I can finish the basement. I have read that I don't want a double vapor barrier, but normally in Massachusetts it seems like you would want the vapor barrier on the warm side of the basement, but I no longer have that option.

What are my options to avoid a future mold problem?
