Floating 5/8" Bamboo Flooring Over Concrete

I want to float my 5/8" solid bamboo over a concrete slab. I've lived in the house for 14 years and tested the slab and there is no moisture coming up. My plan is to glue the planks together and float them over a moisture barrier. I don't want to add a subfloor and nail the floor down. Is there any reason I can't take standard bamboo planking 36" in length and float it as described above? Are there any disadvantages to doing this?
Thanks

I live in Miami Florida (hot & humid) and the property has a monolithic slab foundation.
I installed bamboo floor over concrete. I did not float it, it was a glue down application using Franklin 811 Urethane Mastic. Has been five years and no problem.
