Laying Cables in Reinforced Concrete Walls: Cable Routing, Mounting Boxes & Socket Installation

Hello
Let's assume that the electrical installation in a block made of large slabs - reinforced concrete walls (let's add that it is also made of aluminum) can be replaced, then what way of cable routing, mounting boxes, sockets can be used.
The existing installation was carried out in the floor with the use of sockets and small surface-mounted boxes.
It is not necessary to lay cables in the floor (laid parquet and laminate flooring).
In the apartment you need to build new sockets, let's say 20 pcs. and I can't imagine forging 20 holes in reinforced concrete.
If you have any ideas on this topic, please help.
greetings

Hello.

I live in a block of concrete panels and my electrical installation is under the plaster in the walls. Electric sockets, light switches etc. are surface mounted. Last year, I did a little bit of redoing the installation, moving the contacts, replacing the switches. As for the location of the cable, it could be hidden under the plaster. Since I do not like surface-mounted sockets and switches, I decided to cut holes and insert the cans. When it was a brick partition wall, it was ok, but the stairs started at the concrete. I got a Bosch drill with a hammer and the ability to put on a hammer hammer, plus decent core drills. To make 8 holes for cans in reinforced concrete and I will say that it was not easy. But I talked to a few people and whoever dared to put the cans under the sockets had similar adventures. It is always worse to process than to build from scratch.

Yes, forging is the greatest macabre !!!!
To make it as little as possible, I want to use deep fi60 cans, but I do not know if I can even use lace and a hammer to drill through the reinforcement !!!

A decent lace and the reinforcement. Apart from that, there is nothing else but forging and that's it. There is no other way. As for the cables, if they do not fit under the plaster, and they must, unfortunately, it remains to shoe the old plaster under the cables as much as possible and put a new grinder, or a KG board. Then who taught you to do the renovation from the end, ie from the floor? Now make the walls and finally the ceiling, and after this order the walls and floors can be made anew.

Yes, you can buy lace for drilling holes for cans.

The drill must also be neat:

If you want to run a new installation, you can think about skirting boards with the possibility of running cables, or about plastic trays.

It's not me who is planning the renovation, my friend is asking me for a favor to replace the installation. The case is that everything can be done but at the right price. The apartment has 4 rooms, bathroom and kitchen + new switchgear with differential.
Let's assume that there will be about 20 sockets, 8 light points, a switchboard.
As we can see on the link above, the fi60 crown is over PLN 200!
The question is how much can it withstand in such a hard material, and how do chasers cope with reinforced concrete?
Therefore, it is difficult to estimate the cost of such a "annoying" renovation.
Perhaps one of the forum members will propose a preliminary settlement

friend Bogdanor sent you a link with a hole saw for cans - good and expensive, but I would not recommend - look for something with the possibility of drilling with a stroke. I have such holesaw, unfortunately I do not remember where I bought it.

I can't see the furrow chippers in zelbet, I can't (it will only "jump"). I used to work with a machine that had two blades mounted on one axis. They cut into the concrete, then all that was left was to "break" the middle ... But it's expensive equipment. The "amateur" methods are drilling holes with a thin drill and then forging them (but how much time ..). Besides, it depends on how solid this concrete is, what layer of plaster (maybe it is enough to make a groove in the plaster, without disturbing the concrete, for laying the cable). Also, think about skirting boards or cable trays, then just make them outlets for sockets / switches "plug" and it will be fine.
ps Yes, there are many types of holesaws, but those suitable for concrete will always be expensive. (with or without impact)

It turns out that the matter is not that simple, take a look here:

What do you say ???

You are right, I also come back to my suggestion: installation of a surface (trays, slats - will not disturb the structure - no permits required), while the devices themselves (contacts, switches) are in "under-plaster". If, however, you insisted on "hiding" the cables in the plaster, I do not know .. maybe some professional will write something wiser.

I can tell you that where you need to forge, you need to invest in equipment, which unfortunately costs less, in order to make less money. But I will probably save you forging if you use the skirting boards with conduits for cables and gn. Place the p / t at a height of approx. 10cm from the floor. In the door, also use strips to cover the wires. Unfortunately, for connectors, ceiling outlets should be forged. As lighting junction boxes, you can use connector boxes.
