I just laid 400 feet of "click-lock" flooring on my basement concrete floor.
Your best bet is to lay some 6 mm polly over your floor, put some "good" underpad over this and then lay the bamboo. The polly is to prevent wicking and the underpad is just to make the flooring more resilient and to protect the bamboo from any irregularities. If your floor is really uneven you might want to pour a skim-coat of self-leveling compound before starting the polly.

really attracted to bamboo flooring for my dining room/kitchen<BR>area.
Can it be successfully laid over a concrete floor? I hear<BR>conflicting
advice. One said that it must be glued to the floor, but<BR>there's no
guarantee that it won't move. A search of message boards<BR>suggests
that it's probably ok. Grateful for any
