If you have a basement that occasionally has water issues, would this floor allow any water that comes up underneath to evaporate without damaging the flooring?

The COREtec is a waterproof floor, but not a mold and mildew proof floor; as such, any water that seeps in through the concrete underneath will not evaporate out through the seams. Long term exposure to moisture may result in mold and mildew formation. The floor would need to be taken up and laid flat, cork side up, in order to dry out both the flooring material and the subfloor and minimize the formation of mold and mildew on the flooring.
