Thanks. This is something I haven't thought of. Maybe an 8 mil plastic sheet? I don't know how good the seal would be on the dimple board though. Should I skip the XPS board with this solution and what product would I use to seal at the top and bottom?I would cover the wall with poly sealed at the top. tucked in and sealed yo the dimple board at the bottom so any future leaking goes down and any evaporation from below has no entry to the finished area.
