Wood floor on concrete?

[BML]

The concrete floor is four years old so it has a membrane and insulation under it. I would like to lay an Ash floor if it is not to expensive and if it is then I will use Deal.
I know that the wood would probably shrink so I propose to cut the floor to size and lay it loose for three months or so to dry out and then fix it.
I have three questions:
1. Could one just use “No Nails” and glue the wood to the concrete?
2. Should I cut trenches in the concrete to take lengths of 2X2 securing them to the concrete with expanding bolts fixing the floor to them?
3. Do I need to allow ventilation?

Sorry, I don't think this is going to work. There are two problems here. Firstly, even if the wood is aclimatised to it's new environment, changes within that environement will lead to unavoidable expantion/contraction. Secondly, the cold surface of the concrete will lead to moisture being attracted to the underside of the wood. This will lead to warping.

If I were going to do this, I would lay a subfloor of ply first. (using a bitumous adhesive and screws). Then Glue and Nail the floor to that. This would almost double the cost of the installation, but I wouldn't be confident with anything less. (the nails would be punched below the surface and filled over).

The alternative is to lay it as a floating floor, but this is obviously something that you've already disscounted.

The only way is to use wood blocks flooring with the correct type of bitumen adhesive.
