Hello everyone,
I’m uncertain and need your help. I tried to find something similar in the forum, but it didn’t quite match my situation.
Our house is currently being built by a developer, including a TÜV inspection commissioned by the developer, sold as a package.
The first inspection report came a few days ago and mentioned quite a few defects.
As an example, I’m referring to the waterproofing of the concrete slab (bitumen roofing sheets). According to the inspector, these were poorly executed because they were wavy and might crack during further work on the surface, see the picture. Over the weekend, I tried to check this myself, and the developer apparently has already taken action. However, I can’t judge whether the repair is acceptable or if they just want to continue quickly.
My neighbor has the same problem; in other houses this issue didn’t appear, so it seems to depend on the day’s conditions.
What do you think? Is the repair acceptable in this way? I’m grateful for any assessment. I understand that a proper evaluation can only be made on the actual site, but some opinions or hints would definitely help me.
Thanks and regards
Der Storch

If the expert has pointed out an issue, there should be a written report. Refer to it (attach it) and write a FORMAL and OFFICIAL notice of defects with a deadline. In general, it is better to hire your own expert.
If you see with your own eyes that something cannot be right, you need to speak directly with the construction company. Don’t work past each other; instead, arrange a joint meeting on site. What does the site management, your main contact, say?

There is an appointment scheduled with the construction management on Wednesday for the official first inspection.
My main concern was about the technical aspects behind it, specifically whether the defect remediation in this form is standard practice.
I have my own independent expert, who so far has only given one standard statement: no significant defects.
That may be true, but the other defects still need to be addressed, and there were quite a few on the list.
Therefore, my question is for technical guidance, so I can at least have a rough idea of my position, as I currently do not feel well advised by the expert.

If you don’t trust your building inspector, then find another one; otherwise, it doesn’t make sense. The goal is not for YOU to become the building inspector by asking questions in online forums. (That never harmed anyone, but it only provides limited professional expertise.)

Developer? Then you have no say in that. The client is the developer; in the end, you are buying the finished product.
