Insulation/Framing after Waterproofing
Hello, I recently had a company come out and "waterproof" or water mitigate...my basement, they sprayed for mold, trenched down for a french drain, drilled weep holes around the perimiter and installed new sump pump, they also installed a ventilation system called EZ Breathe which moves bad air out. They lined the walls with some sort of plastic membrane (Vapor Barrier) and a dimpled sheet at the bottom as seen in this photo:

My question is, can i put up rigged foam board against this membrane/plastic prior to framing...can i frame directly over top the membrane? I believe the membrane is a vapor barrier called Vaporbright which is a multi-ply nylon weave and polymer laminate.
I was planning on going out and buying an R-10 rated foam board to fill the Rim Joists and then place on top of the rest of the membrane.
After searching for similar issues on these forums i believe what im looking to do is essentially what is being described as "Option 1" here: Insulate & frame foundation walls with membrane in basement

when you place your sole plate, use tapcons & adhesive as only the Lord knows thickness of replacement conc,,, many cheat & put back 2 or 3" instead of matching existing floor thickness,,, we leave 3" behind the stud wall for air circulation via fans,,, block basement walls ?

Yes, block walls behind the vapor barrier.
Here's a before picture:
I know before i do much else i need to get the Egress window added - a contractor quoted me 5k to do that but im gonna shop around.
For the insulation, code in my area says to use R10 or R13
.
Ultimately Only Half of the Basement Will be Finished, my goal can be seen here:
