Drilling in the balcony floor / ceiling

[Ottosven]

My neighbor and I would like to run a cable between our apartments. Since we live above each other, we think the balcony is a good place to drill the hole.

Could it affect the structural integrity of the balcony if I drill a 10-12mm hole through the slab inside one of the inner corners, about 10 cm from the edges (i.e., the walls of the balcony)?

Erhm, have you received permission from the landlord, the board of the housing association, or equivalent? I assume none of you own the house, right?

No, it will not affect the structural integrity, but don't drill too close to an edge because there is a high risk of cracking.
After you have run the cable through, seal with suitable exterior sealant so that moisture doesn't reach the reinforcement inside the concrete.

This feels like a bad idea. Why do you have to drill precisely on the balcony?

What type of cable do you want to install?

 

[Ottosven]

No, it will not affect the structural integrity, but don't drill too close to an edge as there's a high risk of cracking.
After you've pulled the cable through, seal with a suitable outdoor sealant to prevent moisture from reaching the reinforcement inside the concrete.

Thanks for your response. I will remember to seal it. How far from the edge should one drill? Is 10 cm sufficient?

feels less invasive than just drilling in the apartment floor. Do you have a better suggestion?

What kind of cable do you want to pull?

24 fiber, fiber trunk. 8mm in diameter

At least 50mm from an outer edge, often the reinforcement is 30mm in, so I would start with 50-70mm.

I am curious about the purpose of it all!

since we don't know the conditions, it's difficult to give a better suggestion 🤷‍♂️

since we don't know the conditions, it becomes difficult to provide a better suggestion 🤷‍♂️

Isn't the info in post#8 sufficient?

Data geekery, servers in both apartments that need to be connected

What does it say about what other conditions exist than drilling holes in a balcony that one does not own?

Is it safer to just drill into the floor in one of the rooms? In terms of structural strength, that is?
