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.<br><br><div class="gmail_quote">On Fri, Nov 30, 2012 at 10:24 AM, Freddie DeJesus <span dir="ltr">&lt;<a target="_top" href="mailto:info@eliteflooringandrefinishing.com" target="_blank">info@eliteflooringandrefinishing.com</a>&gt;</span> wrote:<br>

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&#39;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?</p>
