Hello,
we are building a prefabricated house with a basement (concrete).
The basement floor (slab) has already been covered with a waterproofing membrane ("Alujet Floorjet"), which was also extended a bit up the walls and glued there.
The electrician then laid underground cables (electrical cables) on the floor and fastened them to the floor with cable clips and nails.
Is this acceptable?
At these points, the waterproofing membrane is basically slightly "pierced," and moisture could potentially travel up through the barrier via the nails...

It is generally allowed – not only for cable routes, but also, for example, around the base profiles of drywall partitions.
However, all manufacturers of waterproofing membranes recommend additional sealing measures: with Alujet, for example, the anchor holes should be sealed using Alujet Allfix.

Dear forum members,
the original poster wrote the following in their initial post:
Based on the type of sealing (with metal insert) and the way it was applied, this is a SEALING, not a vapor barrier!
Regardless of risk assessments about whether and how damage from leaks could occur, any penetration of the sealing layer is an unacceptable issue.
I can already hear those who try to downplay the defect.
If this were a legal evidence inspection, the responsible company, according to my statements, would have to remove the entire perforated sealing membrane, secure the installations to the rough floor slab, and then apply a new sealing layer above the (now covered) protective conduits.
Who, when, and where someone has already accepted a similar installation in their home is irrelevant here!
No, such an installation as performed is neither proper nor professional and should not be accepted.
