This spring we bought a split-level house built in '88. The inspection report noted an elevated moisture level of 28% in the studs that are directly against the concrete wall facing the bedrock.
We have now begun renovating the room in question and have torn down the drywall and fiberglass insulation to see how it looks.
See attached pictures.
We are considering two options for the wall:
Recreate the wall
We cover everything with an air gap, moisture barrier, insulation, and drywall.
Integrated shelves
We build cabinets and shelves that are mounted directly into the studs, which thus become part of the interior. The concrete is painted with breathable paint.
Since we are quite new to Swedish building standards (we have lived abroad for a long time), I have a few questions I wonder if you can answer.
I have read both here and elsewhere that you should never place organic material directly against concrete, but replacing the studs looks quite cumbersome. Can they remain if treated in some way?
With the shelf option, will there be issues with moisture emitted from the concrete, or will the room's (upcoming floor) heating take care of it?
Does the wall option work if we extend the floor's moisture barrier in the floor (concrete, plastic moisture barrier, styrofoam, particleboard, linoleum) up along the wall to the ceiling?
Have we missed anything that we need to consider/fix before we get started?
