Sean, I was thinking of two things...first, if this is SOG with no vapor barrier, then a constant stream of moisture rising through the slab would show itself in the grout (unless the tile was set over a vapor-blocking sheet membrane).
Also, I would talk to the customer and find out what the cleaning routine is for this installation. I have inspected jobs where the cleaning crew was practically flooding the floor with water and cleaners, and then of course all that water had to go somewhere and then reappear somewhere, usally causing staining of some sort. A common statement that I have heard is "We clean it all the time and no matter what we do this stuff keeps showing up on the surface".:mad2:
