ᐅ Floor insulation not glued or sealed to the screed

Hello, during our new build in 2017, I only just noticed in the photos that the insulation boards in the floor structure were not bonded (sealed) together. The edge insulation strip was also not sealed to the insulation boards. The underfloor heating pipes were seemingly “stapled” directly in place, and then the liquid screed was poured.

Now we possibly have hidden mold within the floor construction.

Who is responsible for inspections and any further necessary actions?

Thank you

If the humidity is between 30 and 40 percent, then it is very likely silverfish. They have been relatively new in Germany for over 10 years.

You can find very good information under Long tailed silverfish NIPH.

I think these are silverfish and not firebrats, right?

I believe it is more likely silverfish. Paperfish have a very elongated body and are less wide.
