Between insulation and foundation exterior walls
Just ripped apart old paneling from a basement room in order to install drywall. I pulled back the insulation and discovered just the concrete foundation. Should there not be something between the foundation and the insulation? Some kind of membrane on tarpaper?. I live in a fairly dry climate so humidity is not an issue in the basement. (Oroville, WA) Or is the tarpaper only installed to the outside of the concrete foundation walls?
