That's a project brother, first place had a cinder block foundation and I was getting water leaking at the cove (wall/floor) corner. Painted and chalk exterior. Last place also had a cinder block foundation. No basement,crawl space was 6' with 2 sump pumps. Floor was cold so I insulated underneath with fiberglass batts. Upon selling with the high moisture of the crawl insulation got moldy. Cost 8k for poly liner and additional sump pump. What a mess. There was a big flood a few years ago and the hydraulic pressure from the water caused a lot of basement walls to fail. Good luck brother π»π»
