We have to redo our finished basement after groundwater made it in following the biggest storm in our area's history. We were "dry" to the naked eye for ~10 years. The walls were faced fiberglass insulation stapled to 2x4 studs that are 1.5" away from the concrete block that was coated with Drylok. When we remediated the water, we noticed enough evidence of block discoloration & possible fungus to reconsider how the basement will be insulated in the future. My question is: can we use spray closed cell foam insulation in the current wall framing followed by drywall to achieve proper vapor barrier against the block and insulation? We'd rather not remove the 2x4's (and metal tracking) to get 2" of rigid foam board against the block and have to reframe the walls. Thank you in advance for your help.
