Cork flooring shows seams and chips

Hello everyone,
we have installed cork in our new building. It is an alleged "quality product" from the company Amorim (Cork Essence).

Here are a few pictures. The "seams" are raised significantly, so you can clearly feel them with your finger. There are also already surface chips (see pictures).

Does anyone have experience with this material? Is this result normal? What causes could be responsible?

The floor is installed over underfloor heating, which it is supposedly suitable for.

If this is really the "normal" result for this flooring, I would definitely never choose it again...

Hello Volker.
Question(s) on the side:
a) Before installation, how long had the cork boards been lying in the room?
b) Do you perhaps know which type of adhesive was used?
c) Was the room in which the installation took place heated?

d) Are joint gaps maintained with walls? e) How strong is the floor or what is its structure?

Hello, I can't answer all questions, unfortunately I'm not very tech-savvy.

a) On the construction site (or in the rooms), the material lay around for about 2-4 weeks before it was installed.
b) I don't know, unfortunately. To my knowledge, the one recommended by the manufacturer.
c) The room was heated. Maybe even "too warm," as the material was lying there during the heating-up phase of the underfloor heating (a possible cause of the problem).
d) Yes, that was checked again. That was our first approach, but it does not seem to accumulate on the walls.
e) I don't know exactly, unfortunately.

For me, the first question is not yet about the definitive cause (although I am grateful for all ideas). Initially, it would be important for me to know whether the described "problem" is normal for a click cork floor (and something you have to live with), or whether it is a defect or could be one. Since I had it built "turnkey," then the investigation of the cause is more a problem for the construction company and not for me.

The question is always also how much water it gets while wiping; it could also be swelling damage.

I can rule that out. We once wiped with a mist damp cloth and immediately afterwards wiped dry. Since then, only swept...
