Repairing Basement Wall After Mold Removal
Hey all,
We moved into a new home last year (built in 1984) and discovered mold in the basement. This is in the back wall facing the backyard of the house. When we cut away the drywall, we discovered a small crack in the concrete foundation letting in a small amount of water during rainfall. The wall has a layer of asphalt felt against the concrete; this had previously been cut in that area of the wall so obviously the previous owners had the same issue and didn't fix it properly. This area of the wall is also missing its fiberglass insulation.
We have dealt with the mold and the water intrusion from the exterior, we now want to repair the wall section. I initially planned on patching the asphalt felt in the cut out section, however upon examining the wall I see the area where it's missing is much larger than the drywall section we cut out. This means we would have to remove a large amount of drywall to fully patch it which would be a real pain.
Researching online I'm getting mixed messages, it sounds like asphalt felt is no longer used and the modern way is to have a layer of rigid foam against the concrete. Would there be any point to installing foam in this small section? Obviously I wouldn't want to redo the entire basement.
Could I add asphalt felt in patches between the studs so that the new fiberglass insulation doesn't touch the concrete directly and leave it at that? Or is that asking for disaster? Unfortunately in some sections the studs are extremely close (\~1mm) to the concrete, so even getting the asphalt felt as a continuous layer in between the studs and wall would be difficult.
Thank you
