ᐅ Defects in the screed – empty conduit missing!

We have just had the underfloor heating and screed installed. Unfortunately, a few things went wrong during the process.

1) A conduit intended for the stove connection in a kitchen island in the granny flat was simply “buried” or removed beforehand. Now we can’t install a stove on the kitchen island (you obviously can’t just let the cable hang from the ceiling). So I basically see only two options: break up the screed and install a new conduit, or skip the kitchen island. But shouldn’t the cables actually be installed under the underfloor heating? So would the heating also need to be taken out and reinstalled? Two other conduits are also not where they should be. However, with those, it’s just annoying and not critical.

2) At one point, the edge insulation strip was missing. Now the screed has flowed into the manifold of the underfloor heating (see image).

3) In many corners, the edge insulation strip was also installed poorly. There are gaps of several centimeters between the screed and the wall.

4) Inside the house itself, the insulation strip shifted around the connections for the kitchen island there, causing some pipes to now be embedded in the screed (see image).

5) The opening for the laundry chute, which was supposed to be square (30x30 cm (12x12 inches)), was made approximately 25x35 cm (10x14 inches). They had just pushed in a cardboard box that was standing there, which was not square. This means the planned insert no longer fits unless part of the screed is removed and the other side filled in (see image).

6) At the transition between the utility room and the hallway, the insulation strip also shifted, so the screed is connected between the rooms. Doesn’t this create a sound bridge? Especially for the utility room, where the washing machine is located, this shouldn’t happen (see image).

7) The installers left some pipes coming directly out of the walls. Some of these pipes are enclosed by the insulation strip, while in others, the strip runs between the pipe and the wall. This seems quite random. How should it be installed correctly?

8) The quote specified anhydrite screed, but cement screed was installed instead. The screed installer said there are delivery problems with anhydrite screed, so they used cement instead. He claimed this wouldn’t disadvantage me. I don’t have a strong preference either way, but making such a change without prior consultation seems odd to me.

All in all, I feel quite a lot went wrong here. Or is this still within an acceptable range? On top of that, there were several cigarette butts on the screed throughout the house. This is probably not a defect, but I found it rather strange.

I would immediately report the kitchen island and the laundry chute as defects and ask the screed installer for clarification. You can also address the other points during this process. Do you have an independent expert or a site manager?

I wouldn’t accept it that way. It looks like the work was just botched... Were the details agreed upon in advance?

That was a recommendation from acquaintances. Probably not a very good one. We haven’t involved an expert yet. I wanted to first see if these are actually defects, since the screed installers are, of course, downplaying everything. I still find the replacement of anhydrite with cement screed strange. I looked it up online but couldn’t find whether one is more expensive than the other.

Oh, and one more thing: In the bathroom of the separate apartment, the underfloor heating was supposed to stop about 20 cm (8 inches) before the bathtub, because a railing will eventually be installed there to assist getting out (it’s for my parents-in-law, who aren’t very young anymore). So what do we have now? The underfloor heating goes almost up to the bathtub, but the screed stops 20 cm (8 inches) earlier.

What does your site manager say about this?

Raise the alarm immediately and get expert advice. This is madness...
