can you be more specific as to what you are talking about

Im thinking your talking about the earlier posted vid.

If so

http://www.basementsystems.com/basement-waterproofing/basement-waterproofing-products/basement-floor/thermaldry-floor-system.html

google - its a wonderful thing

If water leaks in anywhere, it'll follow underneath the flooring and it seems that you won't be able to tell where it came in.

I'm looking for plastic/hard rubber subflooring like Thermaldry that can be purchased for the DIYer.
