We were told originally by the contractor not to put any insulation in the basement. Seemed like a bad idea where we have a full bathroom and the shower pipes are up against an exterior, albeit underground, wall. So, then they put some basic pink insulation up but it's up against the foundation wall and has no kraft facing. Next they suggest (and have a new project mgr who also thought that was a bad idea since it would soak up any moisture coming through the poured concrete) that we remove that insulation, apply UGL Drylock waterproofing to the poured concrete in the shower area only, then install r13 kraft faced insulation prior to the drywall. Again this is just on wall with shower which has plumbing on exterior wall. Any thoughts?

All bad ideas.
A layer of blue foam should have been attached to the foundation with adhesive running vertical.(for drainage)
Wall should have been out away from the foam by a small amount.
Pressure treated bottom plate with sill seal under it.
If you then use R13 unfaced insulation there needed to be a layer of 6 mil. Plastic over the studs as a vapor barrier.
If you went on the website and used the search function under the insulation forum you would find at least 1000 post on this one subject.

thank you! What's done is done and the walls in the rest of the basement are not insulated. We have steel stud walls w/drywall. I guess we'll cross our fingers. I have read some of the info on and there seems to be lots of disagreement on forums like this over whether there should be ANY vapor barrier at all in a basement. The original contractors opinion was not to insulate at all and to allow moisture to move in both directions. We are in the Ohio Valley and get moisture year round.
