The adhesive was supposed to be a 2 in 1 adhesive/vapor barrier product. Shouldnt a vapor barrier be installed for moisture and radon? The floor level is techinically 15 above grade the way our yard slopes. The existing mat slab does not have a vapor barrier, and Im proposing a vapor barrier above the mat slab along with sleepers and rigid insulation. Which would be better?

Hi Jason, I live in Las Vegas where it is hot and dry. Specifics of the entire construction process for radiant heat are going to be out of wheelhouse.

MEADOWS White Paper - Tips on Choosing Vapor Barriers. Thanks for the comment. I would reach out to an organization like http://www.nicfi.org/.
