Installed Crescent Hardwood Flooring 3/8"x5"xRL glued to concrete slab.
Species: White Oak, Gunstock color. In places, the boards are cracking, bubbling effect,
Changing color , etc. Parts of the floor was treated where moisture content required.
Problems where treated also affected. Floor installer claiming water. How can I really know if it water or faulty material. I have been advised that specific flooring has been discontinued.

Thanks.
