Floor plan planning shortly before submitting the building application

Briefly for clarification.
Even with us, after opening the Halo X cans, there was water inside. But it was limited to a maximum of a tablespoon per can and didn’t flow in, but had to be wiped off the inner walls of the can with a cloth.
That was condensation and completely normal.
I think that’s what your electricians mean too.

What you have here, however, probably has little to do with condensation. Because that doesn’t appear by the bucketful (!!!).

Good luck with the matter. I would probably also go to a lawyer. That’s certainly not normal. And it has nothing to do with cleaning water either.
Unless the cleaners messed around inside the house with a hose so much that they actually had to carry their own water out with buckets. They also had a "hose damage" that they only noticed later and now they don’t want it to have been them...

What you have here, however, has little to do with condensation water. Because that doesn't occur by the bucketful (!!!).

We need to separate that. In the ground floor, no one had to carry water out by the bucketful, as far as I understand (but I will clarify that exactly tomorrow; I just need to find someone who speaks Turkish and can translate on site).

In the ground floor, what worries me more is what happened with the water in the guest bathroom, which is said to have come from the area of the pipe vent.

The bucketful of water referred only to the basement. And I think the connection to the Halox cans is very distant there. All the Halox cans were installed independently in the ceiling. I'm not a construction expert, but the water could only have condensed from below, right? What defect should a precast concrete ceiling have so that water runs into the Halox cans, collects there, and then falls downward when the water pressure is too high?

I would probably also go to a lawyer.

A lawyer is all well and good. But they also need to be given a cause. In other words, it will first be necessary to commission an expert to investigate the fault. Nevertheless, I will have a brief consultation with a lawyer on Monday (but no longer with the € 2,600 letter writer).

A lawyer won't really help you either. First of all, they have no idea about the subject matter and will only bring in an expert. The lawyer will only relieve you of your hard-earned money. Only if a lawsuit is pursued against the construction contractor would a lawyer be good or necessary.

I'm not a construction expert, but the water can actually only have condensed from below, right? What defect should a precast concrete ceiling have for water to run into the Halox boxes, collect there, and then drip down when the water pressure is too high?

I think experts are in the minority here anyway, aren't they...? How much water would have to have condensed there to cause such stains on the floor underneath? And it would have condensed in other places as well then...

No one has to carry condensate up in buckets.

I don’t know how much water cleaners still use there. If anything, it is normal water that has run into the basement through ceiling outlets, but I don’t believe that.

So I was in the house again for two hours earlier.

The waterproof concrete itself seems fine to me. The walls themselves show no signs of moisture penetration. If anything is coming from outside, it must be getting in between the basement floor slab and the waterproof concrete wall. At these spots are also the moisture marks, which in one room even reach about 20 cm high – the water could never have stood that high in the basement.

The site manager called. He is on vacation and tomorrow a deputy site manager will contact me and visit the construction site. I will join then. He said he absolutely cannot imagine that anything is coming through the waterproof concrete and that the basement of the house is not watertight. He has paid attention the whole time, his inspector approved the basement before backfilling, our inspector did the same and even praised how well the basement was done. This is what the whole thing looked like:



Instead, the site manager thinks the plasterers definitely had a leaky hose or forgot to turn off the water and then they possibly made a protective claim that it rained in. Because he says since they left the construction without it being perfectly dry, that causes trouble.

Besides the damp spots at the floor level of the basement walls, today I also found and examined the following more closely.

a) Condensation droplets are already forming on the basement ceiling in places.

b) Only three Halox boxes are wet, namely the three in the kitchen, above which lies the flat roof of the kitchen bay window. I was on the scaffolding and took a few photos from outside. I would suspect the darker Poroton bricks are soaked? Also, on the left wall you can see a spot in the Poroton that doesn’t look very reassuring.



c) What they told me about water having entered the guest bathroom, I cannot understand at all. Both the pipe of the pipe vent was completely dry and otherwise I couldn’t find anything wet anywhere in that area.

Ergo, on the ground floor only the matter with the kitchen outlets and the flat roof needs to be clarified and in the basement the cause of the water. Let’s hope the plasterers really just messed up. With the amount of water that must have gotten in there, it really can’t have been caused by rain. It rained even after backfilling and also when the backfilling wasn’t even done yet and nothing got through then either. Somehow it’s not logical.
