Uneven floors in new construction, is leveling compound a suitable measure?
Page 1 of 2
We have bought a newly built 1 1/2 story wooden house.
It turns out that in virtually every room on the upper floor, there are irregularities in the floor, the largest I have found so far is a 13mm height difference over 140cm.
The house supplier has informed us that they will solve the problem by taking up the oak parquet (click), applying self-leveling compound, and then putting the parquet back.
Does this sound like a sensible solution in a newly built house, or is there a better method?

It's probably a simple solution but why is it so poorly done from the start??
What kind of house is it?
Construction?

Click flooring, so logically there is a subfloor. Flooring chipboard if one had to guess.
Laying such against crooked floor joists and simultaneously managing to transfer those dips is quite impressive. Doubtful. The floor has probably settled afterward, so to speak.
Would not have accepted a leveling compound without first finding out the cause.

If I understand correctly, the floor came in pre-made "cassettes," and it would indeed be interesting to know the cause, as several of similar houses built at the same time have the same "problem."
Since it is not a "long depression" but more local bulges, I guess it might be an issue with the quality of these cassettes, with the joists being more the basic structure under these cassettes?
Floor construction according to the drawing:
14 mm parquet
foam underlay
22 mm floor particle board
220 mm joists with 70 mm mineral wool
28 mm sparse panel
13 mm drywall

Agree with OMLAJA, strange that it has come to this. Self-leveling compound is for the symptoms and not for the cause. Maybe consult an external contractor......
It may be that moisture got on the floor chipboard during construction, which then swelled resulting in an uneven floor. I agree with the previous commenters not to accept a self-leveling compound before the cause is determined. The joists are probably not dimensioned to support the weight of the self-leveling compound. No, redo and do it right is what I would have told them.
Now the builder has "fixed" and plastered the floors on the upper floor at a neighbor's house, they ended up with a level difference between the floors in the living room and bedroom, is it reasonable to accept that type of solution in a newly built house?
Now, this does not concern your neighbor's house. If your home supplier can fix the errors in your house properly, with the correct levels, you should be satisfied. If I understand you correctly, the joists are prefabricated modules, which I consider a poor solution in single-family homes. But if the manufacturer can fix the errors, then it's okay? The weight of the self-leveling compound is not a problem. It's a shame you didn't learn about the pros/cons and such before you ordered a house with this system.shogo99 said:
No, it's true that it doesn't concern the neighbor's house, the problem is just that they have indicated that the same method should be used in our house, they solve each room individually regarding unevenness, which can lead to a level difference of 1 - 2cm from one room to the next, and it feels like a joke. The proper solution should be to check at what level the highest point on the upper floor is and elevate everything to that level so that you avoid different heights in different rooms, or am I thinking wrong?Ardexsmitten said:

Very interesting what it depends on. Does the house supplier have an answer to that?
I don't know if it's answers or guesses, I've heard different things: "different dimensions of records used" "shipped over the Baltic Sea", no real answer has been given yet. Either they don't know what it's due to or they don't want to say it, both alternatives are equally bad in my opinion 
It should probably be checked thoroughly, because if it's due to moisture that the boards have warped a bit, it seems silly to enclose that moisture/mold/faulty construction...to cover it with leveling compound so that you are "satisfied" now and they can continue building possibly the same fault in more houses.
What types of drawings can one assume the construction company possesses?
We have received architectural drawings and HVAC, Electrical, etc., but none of these describe in detail how the house is constructed.
Shouldn't the builder have documents on how all the prefab blocks are constructed and how they should be assembled?
And if that's reasonably the case, could there be any reason why they don't want/need to give them to me?

We will hire our own construction consultant to come and inspect when they have removed all the parquet on the upper floor. Together with the house builder's staff, they will lift some floorboards, etc., since the construction company still only wants to plaster the subfloor without having been able to provide a reasonable explanation for why it looks the way it does.
