soild wood flooring

3/8" soild oak, cross cut,direct glue to concrete above grade,2700sq. ft. no joints tite to walls. stained and sealed
do I stand a chance of this working?
what if it was over a membrane?
will the adhesive keep the wood from warping in humid situations?

No mater how far above grade you get, concrete is damp. It will wick water many, many feet. If you used an epoxy that held the wood from moving it will crush the cells when it expands and is constrained. The crushed cells can then act as a weak spot for splitting to start. Ever noticed how a table with fixed 'breadboard' ends splits? The wood expands, crushes the cells, and when it dries and shrinks the splits occur. No finish is moisture proof over the long run. The wood will come to equilibrium with the relative humidity of the environment it is on. All the finish can do is slow the process.
Buy a copy of the "Wood Handbook" from the Forests Product Lab. They have many chapters devoted to how and why wood changes size and shape.

The key word here is "above grade". If the floor will pass a cacl test I'd do it in my house with Bostics Best adhesive.
