Solid Hardwood, Engineered and Laminate Flooring - Peaking and cupping on an Engineered flooring

At the end of August, I moved into a new house. I have engineered wood flooring laid on grade level concrete. It is now four months and the floor has peaking/cupping throughout. The installer is saying that this is normal and will get better with time.

Is the installer correct or do I have a "failed" floor?

Thank you.

Cupping indicates a moisture imbalance. The floor has a higher moisture content at the bottom of the plank. This makes the wood "bigger" than the top layer of wood, causing it to cup. Most likely you have excess moistue in your slab. Do you have any standing water around your house? Did the installer moisture test the concrete before installation? Did you purchase the material and hire an installer? Did the builder contract the work?

Unless you can find a correctable source for the moisture, this will not get better.

The installers, installed it over a wet substrate. Yes you have a failure, that is not going to get any better. Full removal and replacement, is the only solution.

Go to the NWFA website, and find a independent certified wood floor inspector!!! Your going to need it, as the BS has already started. Wait till the finger pointing starts and the dance will begin. I have seen these things carry on for years, before an inspector is brought in to explain the concern.

Rather common, with all the uneducated people asked to do wood installations, when they were installing carpet only, last week.
