My contractor will be installing DuPont Elite laminate. I noticed the recommendation to install a moisture barrier over concrete.
I have concrete floors in my apartment on the 22nd floor. Would this apply to my situation and if so, what do I tell the contactor to buy.
Thank you

It is always best to follow manufacturer's installation instructions. These are found in every box of flooring. You will need a moisture barrier beneath the laminate over concrete. "A 6-mil plastic sheet vapor barrier. Sheeting should overlap at least 7-8 inches and run wall-to-wall. Secure seams with masking tape."

Even though you are not going to DIY, it is best that you read the installation instructions and understand what is involved in the installation to assure that your installer properly installs the flooring. Complete instructions should address subfloor prep, vapor retarder, acclimation time before installation, etc.

Thanks for the advice upfront.

The directions on the box state that the box should not be opened until you are ready to install so if I followed the instructions, I would find out too late.

Yes, you need a moisture barrier over any concrete substrate, be it ground level, or the 100th story of a building.
