Starting the wall slashing under the wiring, it is necessary to take care of the availability of an appropriate permit in the housing office.
Before the eyes there should be a project with a new arrangement of boxes, switches and sockets, as well as a diagram of the current laying of wires in the room.
Stroking is a very laborious process.
In the process of work, it is necessary to organize a good airing of the room, since a lot of dust harmful to the body is formed.
All doors to other rooms must be covered with a damp rag.

Choosing the
tool First of all, you need to choose the tool for wall slashing. Level, pencil and tape measure are the most necessary accessories, without which the work will not take place.

The same shtroblenie will be carried out with the help of special equipment:
- Bulgarian;
- Rotary Hammer;
- Shtruborez;
- Hammer and chisel.
The most convenient way - stroblenie walls for wiring a Bulgarian. Such a tool should be in the garage of any owner.
For work it is necessary to buy a special diamond disk of the required diameter( only one copy should suffice).
Among the advantages of this method can be identified:
- Simplicity;
- High performance;
- It turns out to be a perfectly smooth shtroba.
A significant drawback is just one - a lot of dust is formed, even a surface soaked beforehand does not help to get rid of it.

You need to completely free the room from furniture and foreign objects, open the plowing window.
The most popular way is to slice the walls under the wire with a puncher.
It is more productive and simpler, but has several significant drawbacks:
- A lot of noise;
- High vibration.
On the plaster can form undesirable cracks, which will have to be covered.
Shtroba turns out to be uneven and rough, as if scratched. A nozzle should be chosen for strobing walls - usually a sharp "peak" or a flat "blade."
There is a special tool for shtrobleniya concrete walls - shtroborez.
This is a kind of modified bulgarian, which is equipped with a special platform for moving on the wall and a pair of disks. A dust extractor is also connected to it.
Specially designed for this type of work, the model allows to make a perfectly flat groove for wiring as soon as possible.
Instructions for trowelling
Getting started, you need to determine the type of walls, as the process of strobing under each of them has some individual features.
First of all you need to familiarize yourself with the plan of the house and find out where the old wiring runs. There are special indicator screwdrivers for solving the task.
If grooving of bearing walls is required, grooves can only be made in the vertical direction. Horizontal shtroby can significantly reduce the rigidity of the structure, which can not be allowed.
There is a special snippet for carburizing bearing walls, which describes the basic rules and permissions.

It has the number 3.05.06-85 and also prohibits the laying of the wiring horizontally. You can go around the rules and make a corresponding groove, the depth of which does not exceed 2 cm.
In this case, its maximum length should not exceed 3 m.
Stroblenie monolithic walls and is completely prohibited by the regulations.
Serious damage to surface layers that protect the reinforcing mesh from corrosion is possible. It is possible to damage the hardware itself, which will significantly reduce the reliability of the structure.
If the walling in the panel house is carried out, then, as in the case of bearing walls, it is forbidden to cut the horizontal grooves.
The maximum depth should be selected in such a way that the reinforcement skeleton can not be reached.
Otherwise, it is possible to deform the structure or get a penalty at check.
If the depth is not enough, then it is necessary to apply an additional layer of plaster or to make leveling with plasterboard.
A special diamond bit with a fixed diameter( 65 mm for euro boxes and 80 for domestic ones) is used to drill holes for a socket under a socket or perforator.
By a similar principle, the brick wall and concrete are throttled. The most important thing is to stick to the work plan and a number of rules.
It should be remembered that the creation of furrows along the shortest path - diagonal, is strictly prohibited.
The best way is to drill the concrete walls horizontally from the electrical box, which is often installed on top of the wall.

In places where the socket will be installed, vertical descent is done. So in the future you will not have to guess where the power cable lies.
Carrying out the firing of the walls under the socket, the height of its location can be quite any.
All electrical appliances must be in the expected places and easily accessible.
However, there are several prohibitory rules:
- Outlets and boxes must be removed at least 1 m from the water supply pipes;
- Set the switches at the height of the lowered arm;
- Sockets used most often - at a height of 0.9 m;
- Sockets used less often - at a height of 0.3 m;
- Wiring bends are not allowed;
- When it is impossible to slice the concrete walls under the wiring, the cables are laid in special gutters.
Every 30-40 cm inside the shtroby it is necessary to fix the cable with gypsum mortar or special plastic clips.
After laying the wire, the wall must be plastered.
The prices for services
Before to start the labor-consuming work, it is necessary to take an interest how many there is a strobing of walls by the master.
This will save you from a number of troubles and unnecessary troubles.
In the construction market, the price of wall slashing under the wiring depends in many respects on the wall material( rubles per running meter):
- Brick - from 250;
- Plaster - from 200;
- Concrete, monolith - from 300.
However, the cost of stonewalling the walls for wiring is not limited only to the creation of grooves.
In addition, the following services are offered:
- Electric wire laying - from 30 rubles;
- Putty putty - from 30 rubles;
- Drilling holes - from 50 rubles.
Thus, the prices for strobing the walls of the construction team for many may seem very acceptable.
But if you need a complete conversion of the wiring in the whole apartment, and at hand there is all the necessary tools and desire - you can save a lot of money and do it yourself.
