DriCore -- A good solution?

[alicepalace]

We're looking at underlayment and/or subfloor solutions to use on our concrete slab flooring application. Our family room and master BR are on the ground floor (at-grade) of our split-level house. We'll be installing Konecto Sierra Plank as our flooring but have been deliberating about an underlayment and/or subfloor because of "coldness" issues and "flooring height" issues.

I came across DriCore today in an online discussion and am wondering if any of you have used it and/or have an opinion about whether it would be suitable for us. Here are some of the issues and questions we have. Any help is appreciated!

1. We have excessive relative humidity on this level of the house. In the summer without dehumidifiers running, it's routinely 75% or more. Consequently we won't be putting down wood of any type but we do think we'll use something like RadonSeal to mitigate this problem. Given this, is DriCore a decent solution for us?

2. Would we have to level the floor in order to use DriCore?

3. Could we put the Konecto right on the DriCore or would we need to put another subfloor on top of the DriCore?

4. In the master BR we had a 3/4" plywood subfloor under the carpet that was in there. All of the trim will have to be redone if we "only" go with Konecto right on the concrete because Konecto is so comparatively thin. So the DriCore would be great because it has enough height to take this problem away. But it's only great if it doesn't promote mold/mildew.

Thanks in advance for any/all suggestions/tips/help!
