There are products, mostly designed for finishing basements, that provide a small airspace between a concrete floor and sub-floor. You may want to consider that before the laminate goes down. Of course, the more you add, the more you have to fix door heights, baseboards, etc. If you hire a professional and get some sort of guarantee, that might be a consideration . If you just go to HD and buy material and install it yourself then you're on your own if the moisture continues to be a problem. Let us know.

The moisture is in the air. It condenses on the cool surface of the tile. Just like a cold bottle of beer in the summer.
