What a can of worms this is becoming. We are going to finish our 45-
yr-old basement, and so far, 6 contractors have 6 different ways of
dealing with our moisture problem.
All around the bottom-most foot or so of the cinder block walls of the
basement, the old paint (I assume its Drylok) is falling off and there
is efflouresence too. There is no damp or musty smell, but I know
it's humid down there. Even now, in the winter, it's 60% humidity.
We have never, in 3 1/2 years, had actual water come into the
basement, just this seeping moisture. We have heavy clay soils.
I am afraid what will happen when we put walls up. Everywhere I go,
there is contradicting information, from professionals everywhere:
put up poly, don't put up poly, use wood studs, use steel studs, use
insulation, don't insulate, etc etc etc.....It's enough to drive me
I am determined to do this, but don't want to spend $30K just to have
to tear it all out in a few years due to mold/moisture. And digging
up around the outside of the foundation is too costly for us, probably
The moisture-proofing contractor insists we'll be sorry if we don't
break through the basement floor all around the perimeter of the
basement and install french drains for the water to go from inside the
cinder block walls. This for $6500 on top of the cost of finishing
the basement. I may be misguided, but I don't feel comfortable
hacking into the foundation.
This may be a really crazy idea, but has anyone invented a way of
drilling a hole in the lower cinder blocks, let all the water drain
out, and then filling in all the blocks' spaces with some kind of
filler/expanding stuff to keep the water pressure from filling them up
in the first place?
So what should we do, Drylok + wood studs + drywall + dehumidifier?
I have also read mixed reviews on the mold-resistant drywall, should
we use that?
Help me, I am losing my mind because everywhere I go I get different
