Right now my basement has some inexpensive foam-backed indoor/outdoor
pile carpet rolled out, some drywall interior walls but that's it.
Joists and insulation are exposed, with hanging 48" fluorescent shop
lights here and there; exterior walls are concrete block painted (on the
inside) with UGL waterproofer (the rough white cementious stuff).
We never get standing water in the basement, and we run a dehumidifier
down there. But we do get some mildew or mold in some spots where the
cinder block wall meets the poured floor. Periodically I clean it up
wtih bleach and paint over it again with the waterproofer. It lasts
about 6-12 months and I do it again.
Does this present a problem if I wanted to have some drywall put in to
finish off the basement walls? The mildew would then be behind the wall,
so I'm guessing it would, and that's why I haven't done anything yet. Is
there some solution (dessicant?) short of digging out the foundation of
the exterior wall? (which isn't entirely possible thanks to a deck,
sunroom, and septic tank extending beyond the footprint of the house).
I would also like to avoid a French drain; we have no standing water
inside. I'm just afraid if we do nothing we'd have a huge mold problem
behind the drywall. Maybe there's no simple or inexpensive solution -
but I wanted to check to get other opinions. Thanks,
