There are probably many previous threads regarding this subject but here goes anyway.
I have a basement that is partially below grade with an new 8″ thick foundation with a 2 x 4 wall sitting on top. I don’t really want a shelf all the way around steeping up as the foundation does. What are my options for interior walls? I guess the obvious are
1. Pressure treated furring strips nailed to the concrete for sheetrock nailing
2. Full height walls with p.t. bottom plate
What are the advantages and disadvantages of each and what are the alternatives.
One article in F.H. suggested the basement not be enclosed for 2 years as the water from the freshly poured concrete dries to the inside (the exterior will be waterproofeed so nowhere for the moisture to go). This article is 7 years old and techniques may change, it seems excessive and I need the space very soon.
What about moisture barriers and insulation (batt or rigid insulation).
If the walls are full height I’d reluctantly lose space on the interior dimensions.Also, if I did then should the space between the walls and drywall and exterior be vented (with foundation vents)?
Thanks

I'd install 1x2 treated furring strips, then tightly fit pieces of foamboard between. Foam gaps. Then, if you don't want the ledge, fur out the upper wall to match the lower and insulate conventionally. Do note that it will be difficult to get the wall totally flat so that the boundary between the two treatments isn't apparent.
