Hello,
we are planning to install laminate flooring in the basement. It is often said that a vapor barrier should be placed under the laminate in the basement. Does this still apply if there is already a wide vapor barrier applied on the raw concrete floor?
And if yes, why is it that only in the basement does laminate require a vapor barrier underneath, but not on the ground floor and upper floors?
Thanks!

@ Scout: First of all, I need to apologize! I had focused the overall topic on laminate flooring, as mentioned in the original question. In your case, it is stated that a synthetic rubber floor covering is to be glued onto a floating screed. I simply overlooked that, please forgive me. In this case, there is no need to expect residual moisture rising from the concrete. The only requirement is that the installation surface (i.e., the screed) is ready for installation and sufficiently dry. The flooring installer measures this with a CM device. If this basic condition is met, the screed surface can be sanded, primed, and filled before installation. The PE foil is, of course, unnecessary when the top flooring is glued! Sorry again!
