ᐅ Electrician drills a hole in a partition wall.

Hello everyone,

Today the electrician drilled the outlet holes and chased the slots on the upper floor. In the children's rooms, there should be an outlet on both sides of the partition wall – he drilled so that the outlets are exactly opposite each other, leaving a more or less large hole in the wall.
My immediate reaction was one of concern. The wall is made of 115mm (4.5 inches) calcium silicate hollow blocks. I am somewhat worried that the sound insulation might be completely compromised now. Should I ask him to close up one side and drill again about a meter further along, or is it not as serious as I fear?

Thanks for your input!

An 11.5cm (4.5 inches) sand-lime brick wall and soundproofing? Haha, way too late.

PS: We also have 11.5cm (4.5 inches) sand-lime brick walls, and they are definitely not sufficient between children's rooms if you want proper sound insulation.

Of course, a 115mm (4.5 inch) wall isn’t the best for soundproofing—but we are family, after all. If one person is listening to music quietly or having a conversation, the other doesn’t need to hear everything. That’s why I’m a bit concerned about the hole in the wall.

It would be better if the boxes are not placed directly opposite each other, but does that really make much of a difference at this point? He has to do the plastering anyway, so he won’t be able to achieve the original finish level of the calcium silicate brick wall.

How is the electrical supply supposed to be arranged? Separate on both sides, or will he supply one box through the box on the other side? *pondering*

Assume that the reason he did it this way is because he only made cable channels on one side. In the office and guest room, for example, he simply shifted the outlet holes, then cut horizontal channels and drilled a small hole. I don’t think it’s perfect either, but it’s still better than the “large” hole. Otherwise, it looks okay—just always the shortest cable routes, only vertical, etc.

Where will the cables be installed when you mention chasing? Hopefully along the floor and then only up to the box. Or horizontally within the wall?
