I could really use some advice on a project coming up very soon. Our local private school has a carpet covered cement gym floor that they want a bunch of “volunteers” to cover w/ an actual wood floor. Question(S) are: Any underlayment to sorten or stiffen the wood? Vaper barrier? any warnings, suggestions ( other than, RUN AWAY!) any help would be appreciated. Thanks!

there was a disscusion about a guy who wanted a wood floor for his dojo.
He needed it to be a cussioned floor. There is a web site that has the required stuff to make a wood floor over cement and still give a little. Ideal for what you want. No Idea about price though. Will try to find the disscusion, Unless someone else finds it first.
Thanks for the info so far. It seems what would work best is to avoid eye contact and back out of the room as quietly/quickly as possible :)
ok let's try this http://forums.prospero.com/tp-breaktime/messages?msg=22711.1

I'm no floor expert, but I've been involved in a lot of demo/salvage. The old floors I've taken up were of a couple types. Fir and maple floors were commonly floating on the concrete nailed to 2x2 or 2x3 sleepers on about 16" spacings. The sports courts were recently put on 2x4 sleepers that had rubber pads nailed to them at 16" increments(the rubber was to the concrete.) None of the floors I've taken up have been fastened to the concrete in any way. In the new construction that I've been involved with there was always a vapor barrier if the slab was on the ground(as opposed to a second floor slab.) I wonder if the existing carpet could be left in place and the sleepers set on top of it. The slab must have a vapor barrier already or the carpet would be rotten.
Check with Connor AGA Sports Flooring, don't have a link , but they're on the web. They sell pads to attach to the bottom of the plywood substrate. Figure about one pad per sq. ft. of floor. Probably about a buck a pad with shipping. They also do installs pretty much nationwide, I believe. Might not be in your budget. I'd tape down some polyfilm squres to the slab to check for moisture migration. Then, I'd probably use a poly barrier anyway. Two layer of 3/4 ply. alternating directions, and staggered joints. Gap all joints atleast 1/4 in. Pads attached to bottom layer of ply. Leave space at all walls. If you can't find this type of product, and are interested further. Let me know. I have a contact at one of their flooring mills that is always willing to help.
