Dents in the floors on the upper floor, vinyl makes noises?!

Hello,

is it normal or must one accept that in a 12-year-old prefabricated house the floors on the upper floor develop "dents"? I notice when walking over them that there are depressions and the click vinyl floor makes noises. In the dressing room, the wardrobes creak when I enter the room. Three rooms are affected.

Does anyone happen to have experience with this matter?

Best regards
Oli

No, it is not common for a floor covering to creak when walked on! What is the substrate made of? Could it possibly be a wooden construction? I cannot imagine that it is a mineral screed, as it does not settle in the walking area over the years. (Please provide a brief description of the substrate) ------------------ Regards: KlaRa

Thank you for your reply. They are cement chipboards that look like concrete slabs and were glued at the joints without underfloor heating (from Schwörerhaus). Are there still any chances for improvements from the house company after 12 years?

Of course, there is a wooden construction underneath since it is a prefabricated house.

Wooden construction is of course underneath since it is a prefab house.

Thank you very much for the quick reply. Just for your information: the term "Fertighaus" does by no means necessarily imply a floor structure as a wooden construction! Often, the storey floors also consist of precast concrete elements, which are later worked over with installations, insulation material, and a mineral screed. Well, in your case, it is a wooden construction with fiber cement boards. Your question about possibilities for rectification shifts from a construction-technical basis to a legal basis. Only a lawyer should provide an appropriate answer here; everything else would be useless speculation, including from me. The same applies to the technical area, which I would have to see and open myself for a clear statement. Since fiber cement boards themselves do not tend to compress when walked on, it can be assumed with sufficient certainty that either the insulation layer underneath is involved in the ductility or that the fiber cement boards, insofar as they are fastened on battens, did not have the suitable material thickness considering the support distances. Then they bend (also due to material fatigue) under load out of the usable plane. This means: a sufficient answer to the question about possibilities for rectification can only be given after opening the floor structure and assessing the causes. -------------- KlaRa
