I picked up some of this this afternoon as well. I wanted a way to install tile on a floor in my basement that didn't take up the extra room that DriCore does with the pre attached OSB (I am installing the DriCore in the rest of the basement as it has a 5000 lb/sq ft rating).
But anyway to my thought, if you lay down the platon and then fill in the dimples on the top side with thinset, or some other cement based product (I was also considering quikrete concrete resurfacer, and a few others) and then install cement board over this (I am debating on weather one 1/2 inch panel or 2 1/4 inch ones would be better. Would seem to me that 2 1/4 incher's would help to decouple the tile from the floor to prevent cracks, but I digress). By filling in the dimples the platon wouldn't be able to colapse in on itself nearly as well. I doubt it would make it to the 5000 lb rating but I imagine it would be higher than 1000.

If anyone else has a thought on this let me know.

Also One other thought I have had is to take a masonry blade for my circular saw and periodically (I figure only a few on my 500 sq foot basement) make a channel tward the floor drain. These would only be about 1/8th inch deep (I'm not trying to make a river) and only 1 kerf wide, but since water seeks a level if it were to come through the walls againe (Yes outside measures are being taken too) it would tend to flow tward the drain.
