I’ll second this. In my 70’s home, had the benefit of having bare walls to start. I put up 2” poly iso board against the block wall, sealed gaps with spray foam and insulation tape, then framed in front of that and put in r-15. There is also a French drain installed. My basement is the warmest dryest part of the house now.
