Condensation issue

RustyRatRod said

I don't know where ALL of it is coming from. I know some is coming under the walls both in the rear and on the side closest to the house. I also know it sweats even when it does not rain. It seems to be simple condensation and not pressurized water from underneath, as it only does it on days with really high humidity......which has been a LOT this year.

And of course "I" am no expert either, but I am just saying what I "see".

My garage used to sweat like crazy. I painted the floor , which was very porous and rough , "DONE BY AMATEURS BEFORE I BOUGHT IT" .
It almost completely solved the problem. Musta been coming up thru the concrete for the most part. A drastic temp. change w/ hi humidity
will still get a little, but not like it used to.
Sounds like u need a French drain----------- if u install one u should water proof the foundation as best as possible while doing it too.
