    Thank you very much for such a lively interest in the topic, I'm tentatively scheduled with an electrician to check this installation, as I get new information I'll be sure to share it. From your descriptions, it seems that various wonders of technology can be expected :-D .

    I have a colleague who toils in the renovation of apartments, sometimes he needed help, as it was necessary to smoothly get away with forging - did not hit the apartment without plaster on a large slab - without a problem it was possible to lay the new installation in the furrows formed after tearing out the old one. Plaster was used to compensate for imperfections in the slabs themselves. What you write about, i.e. furrows and technological holes, the old specialists from Elektromontaż mentioned that they met at the German only.

    After all, I showed these furrows in the photos. They were at the Poles in Warsaw :)
    The furrows were not in the hollowcore panels.

    As for this lack of plaster, or this emulsion is not quite true. There was the usual putty and mostly on the ceiling. Mostly, however, there was plaster.

    Are you talking about one slab or the whole building?
    In that apartment what I gave above the photo with the floor, there were factory vertical furrows and holes for boxes under the ceiling and around the switch. And the adjacent wall was with channels in the middle.

    I don't understand a bit.
    I meant that in the slabs (not the whole block :) ) with holes there were no furrows, at least I did not encounter.

    If we are talking about a large slab, conduits for wires were made at the slab manufacturing stage, as were holes for fixture boxes. Mounting furrows only in some places where partitions were made of pro-monta blocks. There is no plaster to speak of, only the joints of the boards were covered with it.
    Otherwise - it was not a great board.


    That is, that I do not live in a large slab, because I have plaster on the walls? They will be surprised at the cooperative...

    I live in a "big slab". - The partition walls are made of "hole" brick, no installation furrows, 1cm to 1.5cm of plaster on the ceiling in which the lighting wires are laid. The entire aluminum installation was plugged or, if you prefer, on the brick or slab abandoned lime plaster.

    Without any problem it was possible to make furrows in the partition walls, ceiling.

    Of course, we are talking about "cutting" plaster, not furrows "big slab".

    There is no option for forging in concrete slabs. End. Period.


    Why ? That a little concrete will crumble ? It is not possible to cut the bars that sit there.

    Every person is a different interpretation of the violation of the building structure.

    Rods with rods and forging with forging
    First cut the furrow and only then possibly forge if you do not have a furrowing machine.

    I had the opportunity to participate in April in a training course on large slab: http://maz.piib.org.pl/index.php/materialy-sz...-swietle-pb-i-przepisow-wykonawczych?start=20 In addition to the presenter there spoke a gentleman from ITB, whose name I can not remember, professionally engaged in the study of large slab buildings. I asked him quite thoroughly about ways to replace installations in large slab. It is not impossible, but difficult. I regret that his statements are not in the materials from the training, because he very matter-of-factly answered the question of where to make what furrows, what holes, etc. You certainly can't do it "on the spur of the moment", you need to know how these boards work and which way and where to run the wires.

    You need to know exactly where the slab is in tension and where it is in compression and which way it works. And how does the colleague want to make the holes for the fixture boxes?

    And from there , I heard a guy forging a metal doorframe and you could hear 6 staircases away forging, so it carries on the concrete.

    And in general, these blocks will one day begin to collapse in the bad sense of the word, so let's not tempt fate.

    Gentlemen it is a pity to argue, the varieties of great slab as mentioned by Luke-O were many. I myself live in a large slab from 1987 and the slabs have factory ducts for the wires and rather most goes in these ducts. In a block of flats built a few years later where the installation was laid by my friend, the wires are laid on the ground without forging channels because, as he said, they were in a hurry because they were wound up most of the time.

    But there is a difference between forging a doorframe, which anyway mustache in the wall, and forging furrows for how many mb - not to mention forging holes for the can :cry: .

    You know the metal door frame, it was poured concrete or something to the wall, a massacre.

    Well, it's a good thing it wasn't me who forged the neighbors probably the seals fell out.

    No no it's not that to this day that's how installations are done. It's all about what the customer wants. Recently I had the opportunity to perform such an installation and because the walls and ceilings were to be left untouched or only cleaned of lumps and possibly pozalepanych holes after rods from formwork. And all the cables of the ceiling even to the switches that went in PVC tubes to a given height sockets from the floor in trays also to a given height.

Topic summary

The discussion revolves around renovating a property in a block of flats built in 1992, focusing on electrical wiring and the presence of a surface-mounted electrical box. The original poster seeks advice on whether to remove old wiring and how to proceed with the installation, given a tight budget. Responses suggest hiring a qualified electrician for installation while performing other tasks like painting and tiling. Participants discuss the challenges of working with large concrete slabs, noting that wiring may be embedded in plaster or screed, and emphasize the importance of assessing the site before proceeding. Various methods for running electrical installations in such structures are debated, including the use of factory-made conduits and the potential for creating furrows for new wiring. The conversation highlights the complexity of electrical work in older buildings and the necessity of professional guidance.
