Open central electrical shaft

Good morning everyone!

I have the following problem: In my house, there is a central electrical shaft in which all the empty conduits run. The picture shows this shaft before it was plastered (a lot of empty conduits inside).

The picture of the shaft was taken on the ground floor; directly below it, about 50 cm deeper, is the main distribution box. What I plan to do now: I want to place my WLAN router next to this shaft and therefore need to lay about four cables down to the basement. Unfortunately, empty conduits do not end in this area, but unused empty conduits go up in this shaft that I would like to use.

What do you think, how was the shaft sealed? Can you simply access the pipes without damaging anything? The plaster is quite crumbly....

Don't understand what you mean..

Possibly expanded metal lath, which has been integrated into the plaster. Just ask your plasterer.

Regarding your question


“Can you simply get to the pipes without damaging anything?”


It’s clearly a NO.


It’s not possible without damage. Or how do you want to open the wall without damaging it? But that probably wasn’t what you meant. You were probably talking about the pipes. Whether you damage something or not, no one can say for sure; it entirely depends on you, whether you work carefully or immediately use dynamite.


How the shaft was closed. How should we know that. It could be as klblb wrote, it could be a drywall in front of it or it was concreted over. Everything is possible.
