Garage slab with no vapor barrier
Everything I read says you should always put a vapor barrier/retarder under a slab on grade. Whats the harm?
My contractor is arguing the point. He thinks the slab will "float" or that the trapped water will be bad. I disagree, but how hard should I fight it?
Its a slab on grade for the garage, living space above that. I may just put 6 mil down myself this weekedn in prep or the pour.
