Why is there condensation behind my basement vapor barrier and what should I do to fix it?
Hi we have a new home with a finished basement, last year I noticed condensation on the concrete behind the vapor barrier and insulation while doing a project. I had never noticed any issue prior, no water on the floor and no smells. It was by accident that I noticed it. It is in a corner of our house and after opening up the walls it dried up. I reinsulated and and a new vapour barrier, and left it for the winter. I opened back up and there was condensation again. I opened up the wall and it is dry now. Like I said our basement is finished and I can only check a few spots, and I have only noticed in one corner. I have had the weeping tile scoped and they checked the exterior for cracks with none noted. It's seems it's coming up from the footings ? Would spray foaming the concrete walls, eliminate this issue ?
