Yup! Dricore it is. It was a breeze to install. I actually got a bit lucky going around corners and such, as once you start you're locked in (pardon the pun
)
I didn't measure accurately and ended up with a 1" strip for parts of the last row, that was really akward to put in. It's also worth noting that I put it in AFTER framing and sheetrock. If I were to do it again, I'd still frame against the concrete floor, but I'd put the subfloor in before sheetrock, it's just easier to get into those tight spots.
Once in a large area, the stuff goes in quickly (it's floating). I use a few spacers, but noticed after carpet that I had a few rocking spots where I could have shimmed better. Oh well. I did about 900 sq. ft. (most of a basement, except a tiled bathroom). A table saw will come in very handy for equally large projects. I did the theater room, hall, two offices, and a closet area under the stairs... another 'fun' area, heh.
Another word of advice, keep the 3/4" inch in mind when framing doors. We also had to do some door opening shaving... ugh! THAT was a pain.
Conclusion: I'm happy with it and would defnitely do it again. I have a much better feeling knowing my carpet isn't directly on the cement, and think it's much warmer as well (and softer). (note: I also did some rooms in a floating pergo floor over the dricore, which is working out great too.)
