Water between Roxul and tar paper
I'm currently in the process of renovating my basement. Code here states that a moisture barrier is required between the insulation and the foundation wall. I installed tar paper, then Roxul insulation. I did this about a month ago.
Today I was ready to put up my vapour barrier. I noticed a large quantity of moisture that has built up between the Roxul and the tar paper. It's not coming from the foundation wall but is strictly between the tar paper and the insulation. Might this be because I didn't put vapour barrier up right away?
What should I do at this point? If I put the vapour barrier up will the moisture that's already there dry on it's own?
