What is being used for vapor barrier between compacted gravel base and slab on grade? I have a spec for “Ruffco 3000 or 4000 poly vapor barrier or equal” and “12-inch laps and seal with mfgr. recommended sealant or mastic.” Give me some product names for the sheeting and the tape or caulk-tube-goo, so I don’t have to stump my lumberyard salesman.
