well for starters there should have been a moisture barrier put in first under the slab. Moisture blockers will work up to a certain level level, but not on every level..we have a lot of moisture problems here in kansas as ..I cannot tell you how many guys I know who have had failed stain jobs in basements, or garages with epoxy coatings that have peeled up.

There could be many reasons for this.  How old is the slab?  I would peform a vapor emission test on the slab and possibly take a core sample for lab testing.

To all partners,
I am on a job where water is coming up through the slab. The home owner had a plumber, engineer, and air conditioner guy come to the job nobody can figure out where the water is coming from. Hey builder that look at the job might think that the house is on a low water line and the moisture is coming from the ground. The water looks like it's condensation coming up and it smells like vinegar. The house is in South Florida. Does anybody have any ideas what this is? If I remove all the tiles and waterproof the slab and install porcelain tile with epoxy grout will that stop the condensation and moisture?
