I agree that dricore would take care of it. Regardless of carpet choice if you do get water that goes above the dricore you will need to pull it up. I too got water and was able to salvage my carpet in the HT but it was not an easy task. The dricore and the padding did need to be replaced.
I spent the better part of today researching at the DRIcore product and others like it. Interestingly, most google searches link back to AVS Forum
Things I don't like about DRICore:
- it has a glued-on OSB layer. So, not only is OSB an organic product that can break down and/or mold when wet, they also made it very difficult to remove the water that might be trapped in the dimples on the top-side
- it's thick! - almost an inch... If only doing the theater room, I'd have to have a ramp at the door to transition to the adjacent room *and* I'd likely have to put another layer of OSB on my riser (so the 2nd row can continue to see over the first)
After reviewing nearly 10 products like DRIcore, I think I like SuperSeal's Carpet Subfloor Membrane
the most. It's only 1/8" an inch, has no organic matter and, unlike Delta FL, doesn't require a plywood to be put on top of it, since its dimples are too small to be felt under a normal carpet pad. On the downside, it only offers 1/16" of an air-gap, whereas DRIcore has 3/8" gap, but my thoughts are that it's OK for what I care about (to keep a wool carpet dry).
If you go dricore you can save some money by also building the riser directly on the concrete and simply dricore the section in between. That's what I did and it really worked out in my favor. I did use pressure treated lumber as the base for the riser and stage, as it appears you also did for your stage.
I already have walls, stage, and riser in place - so this is my only option but, looking at Logan's thread, I'd be disinclined to put DRIcore under any of them!
