Actually I can assure you the MVER will change. It will change to almost zero when a floor is encapsulated with a vapor retarding flooring.

The question we always had to answer is: How much moisture in the slab will redistribute as the slab reaches equilibrium after we place a moisture retarding flooring on it?

The old method of testing was to place a CaCl test on the floor, and guess that the amount of vapor being emitted was an indicator as to how dry the slab was and how much water is trapped within. This method is far too easily fooled, and the newer in-situ probe method is much more reliable.

And yes, I can guarantee a floor will never fail due to moisture. That isn't a stretch to believe.... there are zillions of floors out there not failing. But I would never rely on a MVER test to make that guarantee.
