What Goldstein said, Wolfgang. Not everyone does proper preparation for SOG foundations just like not everyone does proper preparation for ceramic tile installations as evidenced by the threads in our Advice forum.

I'd wanna do some serious MVER testing before I committed to such an installation. I don't recall what Bostik's limit is for that application.

I'd start with several patches of poly taped to the slab in various places that were to receive the hardwood installation. If there is any indication of moisture, I'd then want to do a proper calcium chloride test.

My opinion; worth price charged.
