Damp basement

Hello all

I have a dampness issue in part of my basement. I just ripped out about 2 tons of drywall and what used to be a framed wall (vacuumed up the footers and about 2 feet up the studs). Whoever built this room did a half assed job at it. They did not use treated lumber and no plastic or insulation. The other areas of the basement that have plastic and insulation are fine. Here is my question….Now that I have ripped to the concrete how do I go about sealing that area from moisture?? Do I use dry-lok paint? Does that stuff even work? should I put in drain tile? Are there other options available for me besides digging up around the house and hitting the foundation with a hot mop?? I want to do this so it will last but I do not have thousands of dollars sitting around collecting dust. A little more info on the situation….walls are cinder block (hollow) and I am planning on installing a whole house de-humidifier, no central air so no cold air return (actually no duct work in the house as I have electric heat). I will be installing a pergo laminate floating floor with a DRIcore subfloor. Thank you for your time and suggestions.
