Water Bubbles on New Concrete Floor

[Account Closed]

I have an apartment that is below grade that had a wooden floor that buckled. We removed the floor boards and found moisture coming up thru the concrete floor underneath. 

The American Leak Detection company came out to check water coming into the house, and no leak was found. No sewer/drain line was checked, however. Thinking that the moisture was a result of badly prepped work, we had professionals take out the floorboard, prepped the concrete, added assailant chemical and installed an epoxy coated floor about 6 weeks ago.

We came back yesterday and saw bubbles in some parts of the new floor, mostly in the same spot where the wooden floor had buckled, but also in other areas where the floorboard seemed to be ok before. The bubbles when popped had water in them.

Any thoughts on what the problem might be or things we should check/investigate?

@Account Closed - it seems that you have an excessive amount of moisture in the basement... both the buckling wood floor (I assume wood flooring installed over a sleeper system) and the epoxy floor bubbling are indicative of high moisture.  Curious, was the moisture content of the slab checked prior to installing the epoxy floor?  I'm pretty certain that the epoxy manufacturer has something to say about that and in what applications their product is suitable.

The moisture is possibly vapor (since you didn't mention any flooding), so being trapped by the epoxy floor, it formed bubbles and collected as water.  I would check the moisture content of the walls, concrete floor, wood members in the basement and the air itself - my guess is that they're all reading higher than recommended.
