Electrical cable fixing/nail shot through bitumen welding membrane

Hello, we are currently building a single-family house with 2 full floors without a basement. In the ground floor, a 0.5 cm bitumen waterproofing membrane was specified by the architect and it has already been installed. This week, the electricians were on the construction site and laid network cables and satellite cables, partly also electrical cables, in conduit pipes on the ground / bitumen membrane on the ground floor. These conduits were fastened individually or bundled together with fastening tape. Nails were driven through the fastening tape and the bitumen membrane.

Now my question is: Is this permissible and where is it possibly stated that it is not permissible (standard)? Or under what conditions is such an installation in this form permissible? If the bitumen membrane is damaged, then it should not have been laid in the first place, or am I wrong?

Two more details: The base slab is 20 cm thick and underneath there is a gravel cushion about 65 cm thick.

Thank you for your answers.

Is permissible, because it is about water vapor - even experts disagree on whether the membranes are still necessary. It is not about watertightness like with a "Weiße Wanne". The few penetrations don't matter - of course, you can still put a dab of bitumen on it. My electrician secured the pipes with a hot air gun - but he didn't have to.

I have now considered extensively coating/overcoating the areas where the welding membrane is penetrated (nail + metal strip) with bitumen thick coating. Is this a sensible alternative and should I have it done by the party responsible if at all. I would also do it myself.

If you then feel better...

Is that allowed

Please ask your architect and share his answer with us. Personally, I think it's typical botched work... Totally fine, proven thousands of times, but somehow still wrong. So just splash some bitumen over it and that's that. Whether the electrician does it or you, depends on your architect's answer and whether it is only supposed to be done or if you want it done properly.

And why botch?
