First and foremost concrete slabs in Florida are synonimius with moisture. Most installers dont even bother to test for moisture until its too late.

What should be done before any substrate is placed, is a calcium cloride test. This test will determine how many mills of a moisture barrier to put on, or it it has to much moisture to do anything at all. DO NOT THINK THAT ADDING A MOISTURE BARRIER WILL SOLVE PROBLEM. You must perform a calcium cloride test

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?
