what I would be interested in is how the water gets through the katja lying there ?? at least in the picture it looks like the mentioned katja. normally nothing gets through from below ...

I can't explain it either. The only solution approach would be that the concrete floor might not comply with the WU guidelines and water enters from below, which emerges through microcracks in the katja (?). I can't imagine that the water comes through the locally poured concrete of the floor slab. But at the moment I have no other explanation since walls and ceilings are completely dry. On the other hand, the damp spots do not look like 72 hours of continuous running of the drying device, which has completely swept away many much thicker puddles.

What kind of construction dryer do you have and where does it blow to??

What kind of a dehumidifier do you have and 'where' is it blowing ??

I can't say that off the top of my head, since I didn't set it up there myself.

It's about a 50cm high and 25-30cm deep box. The day before yesterday it was in the building services room. Yesterday it was in the hallway. It blows out the front.

But it obviously completely dried up the thick puddle at the other end of the basement in the ventilation machine room!

The new damp spots are in different rooms than where I've seen the dehumidifier standing.

As far as I remember, the Katja is not approved for this purpose. The Katja is a vapor barrier, but not approved for sealing. So if he didn't have a WU slab, the Katja would be the wrong choice! That a WU slab is not watertight can be possible but I consider it very unlikely. But who knows... where the water comes from is the big question.

Not every puddle is automatically a construction defect. I myself grew up in a new development area and when I remember what we used to get up to on the construction sites ... dumdidum.

From the house?

Yes, from the house. We are considering designing our house in a similar way.
