All of these products seem to be moisture mitigating systems that would allow water to flow freely underneath, and none really mention being a vapor barrier which is what the Wicanders requirement is for use over concrete.If these companies can guarantee you in writing that their products are the equivalent of using a 6-mil vapor barrier, then it should work fine. If they don't, that just means you would have to put a 6-mil poly (like Moisture Block) over the top of the water mitigation system.
