Glue basement insulation?, construction errors, perimeter insulation facade

Hello,
I am new to the forum and we are building with the company Systemhaus Fell from Merzig in Saarland.
We are quite satisfied with the executing companies so far, only - towards the end - there are apparently the "usual" little things that still need to be reworked and for this I would need some advice.

Unfortunately, the basement was only insulated up to the height of the basement ceiling with perimeter insulation (12 cm) and thus the insulation of the outer wall was extended down to the perimeter insulation and then plastered over it. That means the normal exterior insulation will now disappear underground up to the height of the floor-to-ceiling windows once we start building the terrace next year.
The basement ceiling itself is not insulated at the height of the windows. For a light well, some blocks of the perimeter insulation were simply cut out and glued in (see photos).
Therefore my questions:

1. Is it okay that the insulation of the outer facade can disappear in the terrace floor or do we need to consider something here when building the terrace?
2. Can the missing basement insulation simply be glued on?
3. The craftsman who insulated the outer facade told us that we should paint over the transition from the perimeter insulation to the facade insulation again with sealing slurry... so we applied the sealing slurry on the plaster... was that correct?

Thanks for feedback and personal experiences.
If I was unclear or if other information is needed to answer, I would also be grateful for feedback.

Hire an expert for building damage who takes a detailed look at the situation and evaluates it. You should not accept the execution documented with the photos and neither approve nor pay until the expert's report is completed.

The arrangement of the light well centered between the two terrace doors and protruding into the door area is absolutely not acceptable. Construction damage from non-functioning drainage is pre-programmed here. The entire insulation and sealing situation at a terrace door, possibly even barrier-free, is delicate and complicated. It must be planned in detail, down to the last sealing layer before, and carefully checked during execution. The ETICS material in the base area or in contact with the ground has no place there. It is wrong. Up to 30cm above the ground surface, only so-called perimeter insulation is permitted. The waterproofing on the basement masonry and in the base area must be carried out as structural waterproofing according to DIN 18195 based on the moisture load case (soil report). It must also be applied up to 30cm above the ground surface. The base up to 30cm above the ground surface must be provided with a light base plaster that is matched to the perimeter insulation.

It seems that there has been a lot of botched work here. Who is responsible for the detailed planning?

Thank you for feedback and personal experience reports.

For possible experience reports, I would like to point out that these belong in the moderated forum for house building companies, found .

: do you have a house building blog?

Hello,
thank you for the detailed feedback. I do not want to call it botched work yet; after all, we are still in the construction phase and we have not yet given approval; I will discuss the information with an expert and inform the developer. Then I hope that a remediation will take place; otherwise, I will not pay the full amount.

No, unfortunately we do not have a house building blog.

Greetings from the Saarland

And this topic definitely needs to be reviewed as well.

Best of luck wishes Yvonne

What has become of it? I would appreciate a response, as we are also considering this provider. Feel free to reply via PM.
