I've an unfinished 1k sq ft basement in Chicago with 10 inch cement foundation walls. I'll be creating a family room, bedrooms, bath, etc. I have water coming thru the floor--so Im adding drain tile inside around the perimeter at the footing which will go into a sump pit. The company installing the tile tyvek's all the interior cement walls to above outside grade (which goes 80% of the way up the wall). They do this in case the interior cement wall has leaks--then it will go into the drain tile system.
I will build out many rooms in the basement as noted with 2x4 wood studs. What would best practice say about insulating the walls and the cement slab floor (which I will lay snap together luxury vinyl planks on)? thank you
