I noticed today while doing some work in my in the process of being finished basement that there is ice/water on the interior of the sheathing, behind the insulation. The basement is a walk out basement and a portion of the back wall is 2x6 framing with r-19 insulation. The interior of the studs are not wet nor is the interior of the insulation. I do not know where the moisture is coming from nor how to eliminate it. Thanks for your help

Anything I should do to remedy the situation?

The insulation is unfaced without a vapor barrier. Someone had told me to remove the insulation that is currently there, dry out the sheathing and then replace with faced insulation.

There also is a little mildew growth, so I was told to spray it with bleach/water solution.

i suppose on the backs of the insulation may be dirt marks from the air flowing through and the the moisture in it condensating on the outside wall.

you need a vapor barrier to stop air flow. insulation without a vapor barrier is less efective.

bleach/water solution of 9 parts water to one part bleach.
