Perimeter insulation in clinker house

Hello,

we are currently in the final phase of building our house.
The wall structure consists of 17.5 cm Poroton, mineral wool, and facing bricks.
After the work on the facing facade in the base area all around, Styrodur boards were installed on our house down to a depth of about 80 cm. This was also done in the entrance area and at the terrace doors.

The site management stated that this procedure is necessary to protect the masonry from rising moisture.

I myself have not seen this construction method before and now find it difficult to imagine, for example, how one can sensibly build an entrance platform on a solid foundation or create an eaves strip around the house.

I also have an appointment with a construction expert next Monday but would like to ask the forum for advice in advance.
Unfortunately, I have not succeeded in uploading the pictures. The pictures are apparently always too large, even though they are already <1 MB. Does anyone have any tips here?

Best regards
Freedark

Is the perimeter insulation therefore located outside the facing bricks? What is the weight of the facing brick shell? What is between the facing bricks and the backing masonry in the base area?

Without photos, I generally find that difficult.

Yeah, a picture would be good.

Basically, mineral wool is not suitable as perimeter insulation because it absorbs water and is not pressure-resistant. XPS is the standard there.

XPS is definitely solid. Entire houses stand on it.

There are entire houses on it.

But better not facade panels.

First of all, thank you very much for the answers. Now I have also managed to attach a few pictures by further reducing their size. I think this will make the situation clearer. I look forward to more answers.
