My concrete sub on a Phoenix strip mall got torn apart for poor vapor barrier sealing
The inspector said 'Your taped seams will fail in a year with this heat' and made me redo the entire 15,000 sq ft barrier with fluid-applied sealant. Has anyone else had to switch methods after a failed inspection, and did the new way actually hold up better?

Okay but what if the inspector had a point? Phoenix heat is a whole different beast, it destroys stuff that works fine elsewhere. That tape adhesive dries out and turns to dust. I've seen it happen in under two years on a slab here. The fluid stuff might be a pain but it bonds right to the concrete, no seam to split open. Sometimes the old way just isn't the right way for the place you're in.
