Hello everyone,
since the electrician unfortunately forgot to install the requested conduit for the photovoltaic system during construction (and I only noticed it too late), the cables had to be routed from the outside. A hole was drilled in the basement wall to the outside for this purpose. Once backfilled, this will be about 70 cm (28 inches) below ground level. The drilling went through the masonry, the bitumen waterproofing membrane, and the perimeter insulation. For sealing, black silicone was simply applied around the protective pipe and the perimeter insulation. To me, this doesn’t seem sufficient. What is the usual procedure in such cases? I was thinking about applying waterproof slurry around the area. Or are there other options?
Thanks and best regards

Since I have repeatedly, including in writing, emphasized to the photovoltaic provider how important proper installation of the house entry is to me, I will insist on remedial work here. However, I am not sure how this should be properly done according to current standards. How should it have been done better?Regarding the free space in the multi-service entry. Usually, one out of four conduits is free.S

About the free space in the multi-utility duct. There is usually one free out of four.Unfortunately, there are none. The energy provider and telecom company have installed their own building entries with their own components.S

k-man202114 Jun 2021 19:11I’m not an expert, but as a homeowner, I wouldn’t accept that. Take a look at uga.eu, for example; they have the FHE Flexible House Entry type, which seems suitable to me. If in doubt, I would hire an inspector or construction supervisor. Any damage or problems later on will be more expensive...

Stefan2.8415 Jun 2021 07:12I have also pointed out several times that this topic is important and that the building penetration is carried out according to the current state of the art. Applying a bit of silicone around it seems to me to be the wrong solution....
