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...

Unfortunately, I’m only now getting around to replying. I’m still building a house on the side…
Since we are currently at the exact same stage, I was curious and checked our basement.
Result: the electrician used adhesive, the plumber used nails. See pictures.
I would also be interested in how this should be done correctly!
