Menards and Home Depot have roles of a dimpled plastic product that you lay down first, plywood on top, it is not secured. It works like the drylock panels, but cheaper.

Thanks for all the ideas guys I'll check them all out and try to figure out what will work the best! I need 1/2" as the rest of the floor will also be laminate!
I just did a whole basement (1200SF) with laminate. It was very uneven, lots of cracks, and in a moist subgrade area. Checked all levels and determined high spots. Highest point became the reerence level. Prep: Used a cup shaped carbide concrete grinder in a 6" anglehead grinder to remove all paint and previous tile cement, gouged out all the cracks with a diamond saw blade in power hand saw, filled with epoxy patch,and put a layer of drywall fiberglass tape over all cracks embedded in epoxy. Finish: Went to a contractor specialty supply (the big box stores do not have the big sacks) and bought a pallet full of high grade self leveling underlayment. Installed a piece of ripped lumber (thickness based on reference level) at each door (5)and Rolled down a coat of masonry latex bonding agent. Mixed underlayment per instructions (water is critical measurement) and poured in place one room at a time. A small bull fload works well to consolidate and spread around. After curing of underlayment rolled down a heavy coat of asphalt waterproofing emulsion, put down a 15# asphalt roof felt in the emulsion and put two coats on top. After that cured I layed the floating laminate floor on top. Turned out beutiful. total material including laminate was less than $1.5K. Costco was closing out laminate at 50% off which helped on the cost.
Depending on your conditions; some of the above steps can be bypassed. I had the worse of all conditions to mess with.
I would not hire out to do this for someone else for less than $3K labor cost.

Wow sounds like alot of work!! This is new concrete it was an add on 22'x10' to the existing older house...and it is above grade so other than the moisture in the concrete it shouldn't have a water problem..
