Due to a plugged foundation drain, our basement was flooded with about 12" of water. I pumped the water out, but mold formed on the drywall walls, and the bottom of the walls remained wet. I sprayed the mold with bleach, cut 16" of drywall from the bottom of the wall all the way around the exterior, and pulled out the visible fiberglass insulation. I also removed the vinyl flooring. There is plastic over the concrete wall. The interior wall consists of a wood frame wall with fiberglass insulation and paper backing, and drywall with no air space between the two walls. The concrete floor has a poor finish and the top of the floor crumbles ever so slightly leaving a fine dust.

I plan to put hydraulic cement where the concrete walls meet the floor, and monitor my foundation drain. I would appreciate some help in determining the most appropriate way to address the situation with the walls and floor. Will the double vapor barriers trap moisture and create problems later on? Is there some way to avoid taking the entire walls down? I don’t think I could pull the insulation out because the paper backing is stapled to the wall. I don’t see any mold, is that problem likely to be gone? If I must take the walls down, what other options are there for new walls and insulation? Should I use moisture resistant drywall? Can I use a floor leveling compound to prepare the floor for laminate flooring? Would another type of flooring be better? Thank you for your help.

Sounds like you have things under control.

One thing you do not have is a 'double vapor barrier'.

The plastic sheeting directly over the foundation wall is there to prevent ground water vapor from penetrating through the block and entering the basment.

The vapor retarder on the insulation is there to control the flow of moisture through the framed wall so that is won;t condense on the cooler block surfaces.

Both should be there. Both serve separate functions.

Your next project should be to install a sump with a sump pump and battery backup to avoid future flooding.
