I had electrical boxes installed inside the basement area with waterproof concrete walls. Somehow, the electrician also ended up creating three electrical boxes on the outside. It seems these were nailed to the formwork boards to hold the interior boxes in place. The question now is how to best seal these from the outside. The current idea is to use concrete and repair filler. After that, as planned, a bitumen layer will be applied, followed by 12 cm (5 inches) of perimeter insulation and a dimpled membrane. Drainage is already in place (house on a slope).
Is there an alternative to using concrete and repair filler?
I would appreciate any advice.

Hello.
To make sure I understand correctly, you had a waterproof concrete basement built where, due to an electrician’s mistake, interior outlets are now protruding to the outside? And you want to fix this issue yourself?
In my opinion, the first thing to clarify is whether you actually need the structure to be waterproof concrete, as this will determine the possible repair options. However, I cannot provide advice on those options.
It would be a mistake to try to fix it yourself, as the repair is prone to errors and the responsible party is known. Your first point of contact should be the electrician, who should be liable for the damage they caused. Possibly also the basement builder, who might have been able to detect the mistake before pouring the concrete and should then have raised concerns.
This is, of course, just my personal opinion.

Hello Joachim
Please explain in more detail how the issue occurred.
The electrician nailed the empty conduits onto the external sheathing. No conduit pipe or anything else attached?
There is a resin specifically designed to protect cables from moisture. I would fill the empty conduit with that resin and then apply a thick layer of bitumen over it.
But it’s true: don’t do this yourself. Let the electrician handle it. Stupidity must be punished.
