How and what to post the walls for wiring: briefing on construction work

Upon overhaul or decoration of the new building, all masters are faced with the need to supply communications and masking wires. The best way to lay engineering networks is to place them in the wall. The work is quite laborious, requires certain skills and the availability of special tools.

We will tell you how and how to stroke the walls for wiring, when you can do with an inventory by hand, and when it is better to use professional equipment. We also describe the features of the preparation of the furrow on different walls, we give a guide for stroke and sealing channels.

Requirements and norms for carrying out a bar

Before choosing a tool and accepted for work, it is necessary to draw up a drawing of wiring electricians in an apartment or private house, taking into account construction standards (SNiP 3 regulates the requirements.05.06-85).

The scheme needs to indicate the location of all lighting devices, distribution boxes, sockets, switches and a route along which the connecting wires will be held.

Be sure to save the wiring scheme for the future, if necessary, drive a nail into the wall not to guess whether you will get into the wire or not

  • The depth of the furrows should not exceed 2-3 cm, and the width is 3 cm.
  • The maximum length of one channel from the camshaft to the switch or device is 3 m.
  • The wires and, accordingly, the strokes for them can only be carried out vertically and horizontally, accepting the level of parallelism with the main structures of the building. But reduce the distance “directly” with the help of oblique and even more wavy lines. you can’t. An exception to this rule can only be wiring in the attic room. in this case, the grooves are pierced parallel to the lines of the walls of the walls.
  • The minimum indentation from the floor slabs to the horizontal strob should be at least 15 cm, and from the heat and gas traffic- at least 40 cm.
  • The vertical wiring should pass at a distance of 10 cm or more from door and window openings.
  • It is important to plan the wiring so that the wires have as few bends as possible on the way from the distribution boxes to lighting devices or sockets. Ideally, you need to run the way straight from the box or use no more than one transition at right angles.
  • On the load.bearing walls, floor slabs and corners cannot be stroked. this can weaken the strength of the structures of the entire building and lead to an accident.

The restrictions specified in PUE will clearly demonstrate the following photo selection:

last, corner, grinder, wire, other

In the Decree of the Government #508, in its paragraphs 10.3 and 10.11 states that the device for the hidden laying of the wiring is allowed only in interior partitions

Corner Grinding with the Carbide Rasp and Multi Tool

In the walls of panel and monolithic concrete houses, the depth of the fine should not exceed 20 mm. If the requirements are not observed, it is possible to damage the reinforcement and significantly reduce the bearing capacity of the wall. In brick and concrete blocks it is allowed to last up to 30 mm

In accordance with the requirements of the PUE, it is forbidden to lay tracks of hidden wiring with a slope. They must be strictly horizontal and vertical so as not to create prerequisites for damage and current damage during subsequent work on the arrangement and repair of the premises

Ideally, it is recommended to lay strokes in a layer of plaster or in boxes attached to the wall so as not to reduce the bearing capacity of walls of any category

If you perform a drawing and subsequent stroke in compliance with these rules, hidden wiring will work without problems and failures.

tips for walls for wiring

Very often, when repairing premises, it is required to replace old wires with new. After all, the new modern wiring withstands all the requirements of the n-lice amount of household appliances in the house, while perfectly observing fire safety. Often the owners also want to install additional sockets. This is much more convenient than to carry several extra meters of extension cords everywhere.

The new wiring is best hidden in the walls. both safe and it is nice to the eye. To do this, it is necessary to carry out the cutting in the ceiling or walls of in.depth channels of standard sizes, in which the cable is then placed. At the end of the work, the recesses are covered with a solution or putty. This technology is used not only in case of capital home repairs, but also for cosmetic, and even in the construction of new houses with the installation of the pipeline.

So where, after all, start? How to stroke the walls for wiring?

Norms and restrictions when strokes of walls for wiring

Before proceeding with the tool to the wall, you need to properly prepare for the process. Initially, it is necessary to calculate the wiring plan on a piece of paper. Outline the places of future outlets, switches and lighting points throughout the house. There should not be too many of them. Each element should be defended by a vital necessity. It is also necessary to take into account the materials of the walls and determine the best way of stripping this material.

Regulatory documents on the distribution of wires are collected in SNiP.85. It is best to study them in detail once, so that then do not redo everything again. Here are the main points that should be focused on when performing work:

  • A strobe (deepening) should be carried out strictly horizontally or vertically. The oblique lines should not be present. The only exception when the wiring needs to be diluted on the walls with a slope, for example, the attic. Then the highway can pass in parallel to the tilt of the wall.
  • Between two electric points, you can turn the groove only once. Each turn is a piercing cable that will heat up more in these places. Such conditions can lead to dangerous situations.
  • Shtrobes have a limit on size. The maximum allowable groove width is 30 mm, and the depth is 26 mm. The total length of the route from the distribution box to a specific point should not exceed 3 meters.
  • It is necessary to follow the indentation: from the battery and gas pipes-at least 40 cm, from the door-10 cm, and from the ceiling and floor at least 5 cm, although it is desirable, it is still desirable to adhere to 10 cm.
  • It is forbidden to make a stroke on internal supporting walls. The thickness of the external walls from a shallow groove will not suffer, but on the supporting partitions you need to take permission of the municipal organ. This is especially true for panel houses. The stroke of the walls for wiring on the first floors should be carried out with special accuracy. the lower walls hold not only the roof, but the entire building.
  • It is impossible to touch upon a tilt of a reinforced concrete structure. This may entail a violation of the integrity of the structure and, as a result, the loss of its reliability. If necessary, grooves in reinforced concrete should be shallow, and the reinforcing mesh is not hurt.
  • When making grooves in the ceiling. you need to calculate the shortest way to the lighting point.
  • In the floor slab of the ceiling, it is forbidden to make strokes. If you need to conduct wiring on the floor, then the best solution will be to make it in a concrete screed. It needs to be poured with calculation on the grooves for wires.
  • Brick walls are easier to cure than concrete. This must be taken into account when choosing a tool and the presence of appropriate skills.
  • With a shit, it is necessary to protect the respiratory tract from dust with a mask or respirator.

Important! Shtrust always occurs with increased noise effects. The whole house will hear your work, thanks to the inevitable vibration of the walls. Therefore, such work should be carried out on weekdays from 10 to 17 hours. Then the mutual understanding of the residents will save your nerves and during the neighboring repair.

Methods of stroke

There are four main ways to make grooves. Their main difference is the use of the tool and the application of the use of this technology.

  • A hammer and a chisel. The disadvantage of this method is the inconvenience of work “grandfathers” tools. Even with good dexterity, it comes out for a long time and with crooked highways. A huge plus can be called the cost. it’s cheap definitely.
  • Shock drill (peorator). Minus. strobe with uneven edges. Pluses. process speed and relative cleanliness during operation.
  • Corner grinder. Cons. a large amount of dust, which is difficult to assemble even a construction vacuum cleaner. Plus. even recesses in a short period of time.
  • Strobores. Minus. the high cost of the tool. For one.time use it turns out too expensive. Pluses. fast, not so noisy, even edges of the stroke, without dust.

Preparation and marking of the working surface

First of all, it is necessary to check the walls for the old wiring. To do this, there are special testers and indicators, the principle of which is based on the overall electricity scheme. It looks like this. from a common circuit to an electric point, for example, two wires are suitable for an outlet. phase and zero. On the phase there is a current from the chip to the point constantly, regardless of whether something is connected there or not. The zero wire is voltage only when the device is turned on. And only then is the current return back to the switch. Indicators catch a phase wire. In many indicators on top there is a special light bulb, which lights up when the target is found. This stage of preparation is necessary to protect yourself from electric shock.

After the check, you need to draw the future route on the wall. from the camshaft to each connection point.

Before starting work, be sure to cure door openings with a damp cloth or building film. Do not hope on a tightly closed door. small particles of dust will still find a loophole.

Stroke the walls for wiring without dust

When making repairs in an apartment or house, each owner faces a stage when you need to lay a new wiring. This is done in order to install new outlets, since there are no power supply in the estimated places of their placement. It would seem: I bought an extensive wire, invited a professional and the end with the end. But the work of the master is not free, and you can stroke the walls for wiring and yourself. It is enough to carefully study the material of the article and correctly put it in practice.

How to stroke a concrete wall correctly

Before starting work, take a sheet of paper and a pencil to schematically depict the passage of the wire, the exact locations of the switches and sockets. For this, it is recommended to familiarize yourself with the set of the rules for the distribution of electrical equipment in documents 3.05 06-85 SNiP. Many people think that they know how to stroke, but in reality a stranger with elementary at best leads to a dead end of an electrician-amor. It is better to read the main points once and do the job efficiently. Below are 6 basic requirements that need to be guided by:

  • Do not carry out horizontal stroke further than 150 mm from overlapping plates.
  • Beware of vertical grooves near gas pipes. The distance from them should be at least 400–450 mm. Corners and windows should be distant by at least 150 mm.
  • Stroping the walls can only be horizontally or vertically. Ideally, there should not be extra tilts. The exception can only be the design of the attic: here the wiring is laid parallel to the wall tilled.
  • The length of one continuous furrow should not be more than 3 meters, and the depth and width. 25 mm.
  • As well as inclinations, there should be no turns. The transition to the switch and outlet should be at one angle (the passage of the horizontal to the vertical), except with the joints with a horizontal surface.

Important! Horizontal stroke of the supporting walls is strictly prohibited. This rule applies to absolutely all buildings in any regions. For panel houses, these are all walls. In this case, you need to watch a video tutorial for your layout.

Having studied these rules by drawing up an action plan, determining the location of the wiring and outputs, you can begin. Do not forget about safety precautions. Any construction work requires attentiveness and accuracy.

The choice of tools

There are a huge number of methods of stroke for wiring. They are distinguished by the use of different tools: a barborer, a peorator, corner grinder, a chisel and a hammer, a shock drill. The first method is famous for the perfect result (even slots), but has a high cost. The procedure is performed very quickly and has a relatively low price. Shtrusting corner grinders gives even furrows, but creates a lot of complicated garbage. The only plus of the chisel with a hammer in this case is cheapness. But if you want the work to be of high quality, do not spare funds for tools.

How best to make furrows, choose yourself. The work depends not only on the tool, but also on the master, so it is better to once again check the correctness of actions than to redo the work twice.

How to stroke the walls for electrical wiring by a pedorator

The stroke of the walls with the peorator is the most popular of all existing. This is explained by the fact that this construction procedure does not require much time and means.

Before starting, it is necessary to conduct classical wall preparation. It is no different from the one that is carried out when using other tools. All stages are extremely simple, but require a responsible approach to the master:

  • Checking the availability of old electrical wiring. Sometimes unpleasant moments occur when wires from the old electricity circuit are in the walls. Do not risk life and health, carefully check the surface. There is a special device that quickly copes with this task.
  • Directly marking the wall. Having made sure that there were no wires left in the wall, you can proceed to the schematic marking in the places of the alleged passing of the wiring. Draw lines from the central distribution box to current sources (switches, outlets, lighting wires).
  • Protection against dirt and dust. Do not forget to hang windows and doors: the process is not too clean, dust will spread throughout the room, and it will be difficult to remove it.

After finishing the preparation, proceed to the main actions. Take the poorator and along the pre.drawn line drill small holes at a distance from each other about 1.5 cm. Then it all depends on your tool: either you switch it to a mode designed for stroke (you need a special nozzle), or insert a simple drill. Gently connect the holes, moving the peorator.

Important! If you are a beginner, do not neglect the holes, since without experience of such work it is quite difficult to achieve a perfectly even line of lines.

If you still have questions, below is presented

Corner grinder with a bar

Corner grinder is another tool that will help make wiring slots. How to cut a concrete wall with its help? It is necessary to have a diamond disk, since the wall material is very durable. You can consult with a professional, and he may tell some other disc. But do not complicate the task: it is easy to get diamond, plus everything, with it the work will go much faster.

Norms and restrictions when strokes of walls for wiring

There are regulated standards that need to follow. They are reflected in SNiP 3.05.06-85. Their list is as follows:

  • The maximum depth of the strobe is 2.5 cm, width. 3 cm, the length from the opening box to the outlet of the light device is 3 m.
  • Stroke under cables can only be in a vertical or horizontal vector.
  • Paragraph 2 excludes the walls from the attic, since they have an inclined position. They are stripped in parallel in relation to the slope of the roof.
  • On the wall surface, the minimum distance from the floor slabs is 15 cm, 40 cm from the gas pipeline and batteries, 10 cm from the window and door.
  • Electric wiring should have a minimum of bends. I recommend that they exclude or allow one turn at an angle of 90 degrees.
  • Shtroting is prohibited in places such as: corners of the room, carrier walls, floor slabs.
  • Due to the formation of large volumes of dust, protection is required: respirator, glasses, mask, etc.D.


Prior to the start of the operation, paper displays a diagram with the installation sections of all points and circuits of the planned laying.

DIY wiring for wiring is accompanied by increased noise. The walls begin to vibrate, and this is given to all neighboring apartments. For this reason, carry out such operations on weekdays from 10 am to 5 pm.

Schooling corner grinding for wiring

A two.handed device is great for tearing dense concrete, creating numerous long channels for wiring.

For normal operation, in this case, a diamond disk is used, since its strength allows you to successfully perform the planned volume of work.

The creation of narrow lines will not require attracting other devices, since there will be enough thickness of the cutting disk. Otherwise, the side lines are cut out by the angle apparatus, and the central part is cleaned with a jack of law.

Shtroting is performed at low power: 500 watts are enough when using high.quality cutting nozzles.

Few people know about this function of the ANGLE GRINDER! Brilliant Invention!

It is important to observe safety precautions when working with a corner saw, hold it tightly for both pens. The device cannot be allowed, since despite the likelihood of instant shutdown, the rotation of the disk will not stop immediately. There is a high probability of damage to the legs, floor, walls, nearby people.

So that the milling cutter does not fly after the first cuts, you need to tighten the fastening nut tight.

Preparation of walls for stroke for wiring

Before cutting the borders of the groove, they must be marked with a construction pencil. If this is not a new building, then before marking, using a probe or a tester, make sure that there is no old wiring in this place in this place. Not to accidentally damage her.

What else needs to be paid attention to? All strobes and wiring are laid either strictly vertically or horizontally. Why is this being done? When we put the switches, sockets or some other element on the wall, we should always know exactly that electric cables are coming from this place, or strictly vertically up, or vertically down. Under the ceiling, the wire goes only horizontally, at a height of 10-15 cm from it. Often sockets are placed close to the floor. Therefore, after many years you will understand that you cannot definitely drill the wall over it. neither hanging shelves, nor fasten the paintings, etc.D. And so throughout the house. This rule is mandatory for everyone and everywhere.

Before cutting the borders of the groove, they must be marked with a construction pencil.

Stroke process by various tools

The stroke of the walls for the wiring will be required:

last, corner, grinder, wire, other
  • Construction pencil;
  • Roulette;
  • Hydraulic level;
  • A strooboresis with a metal disk and a connected vacuum cleaner;
  • Jackhammer.

Strokes of walls begins only after approval of the wiring plan of electricians. The first stage is a mark of places of sockets with switches according to the apartment plan. Wiring is carried out separately for household appliances: TV, intercom, ventilation, alarm, and t.D. The height of the location of the outlet from the floor is noted, then the distance from the slope of the door or window, the corner of the room. Future points of sockets with switches and vertical spaces of drinking walls are strictly noted in level. The wiring all stretches along the ceilings:

Very responsibly you need to approach the wiring in the kitchen, due to the large number of household appliances included in the mains. Sockets must correspond to the height and placement of kitchen furniture and connected appliances.

The first stage is a mark of places of sockets with switches according to the apartment plan.

Stroke a wall or a strooborus, or a disk saw with a corner grinder with a metal disk and a connected construction vacuum cleaner to a depth equal to a pipe diameter of 10 mm and a width of about 30-40 mm for a rosette or a switch. If one channel carries several wires, for example, electricity to the TV, phone, intercom, then it can be made wider. You can also put in it not one, but 2-3 tubes.

During work, we must not forget about safety precautions. When the strobe is finished, places under the boxes with switches are marked under the boxes. If the hole turned out a little more than the box, nothing to worry about. After the wires output into the box, it is walled up into the wall.

After the paths are cut out from the two sides of the canal, the gap between them is processed by a jackhanted hammer or a pedorator. Excess concrete from the tubu. You should not be very much to ext the wall.

When all the channels are cut, you can lay the wiring in them.

During work, we must not forget about safety precautions.


The method of forming a deepening by the penetrator has also established itself from a good side. By the way, when using this dust tool, less is formed. Two nozzles are needed for work: drill and spatula. On the drill, retreating from the tip, the mark is glued in order to control the depth of the holes.

Consider how to make a strob for wiring with this unit:

  • According to the marking, holes are drilled at a distance of 1-1.5 cm from each other;
  • The nozzle changes on the shoulder blade;
  • In the “without drilling” mode, “jumpers” between the holes are removed;
  • Side bevels are equal.

By the way, holes for camshafts, switches and sockets are also made by a peorator. In this case, a special nozzle is used. crown.

It should be noted that the work will be quite long and noisy, and the quality of the grooves is not entirely good: irregularities and chips will be. However, this is not a reason to refuse to use the peorator. All shortcomings can be fixed using plaster.


With this electric tool, you can professionally perform excellent quality furrows in any mineral foundations: from brick to foam concrete. Many people believe that the stroboresis is a type of corner grinder. However, it has a number of design features that allow you to carry out work 2 times faster and with the minimum level of dust.

  • It has two parallel sawing disks with diamond spraying, the saw depth can be set on your own.
  • The stability and accuracy of the tool are provided by the guide roller salamings.
  • The surface protection from damage and security of the employee is provided by the immersion system: when extracting cutting elements from the grooves, spring.loaded slides are lowered, and the discs become inaccessible to contact.
  • Politic absorption occurs in a protective casing and is transmitted to a pipe in a collection of an industrial vacuum cleaner.

The principle of work of the furrow is simple and is that the operator sets the necessary depth of the grooves on the disks and leads the device along the intended line. Then the inside of the gutter is removed with a chisel. The lines are perfectly flat. Buying this tool for personal use is expensive, so it is better to invite a professional.

Work on wood and aerated concrete

When laying the strobes under the electrical wiring in the wall of wood, you can use all tools, excluding the peorator. A bit can be replaced with a chisel that will help get rid of excess wood between the edges of the furrows made by corner grinding.

The wood is not used by diamond, but a circular disk. Instead of dusty formations, a small amount of sawdust is formed.

Ass concrete blocks are easy to process, so they are quite suitable for arranging grooves with manual barbrises. They are used in two situations: for stripping on horizontal and on vertical surfaces.

Both types of hand tools have common advantages: low price, low weight, simple design and reliability in operation, as well as minimal dust formation and noiselessness. It is possible to use corner grinding with circular nozzle.

Cable installation and installation of sockets

There are two types of wires in the stroke. The first provides for the laying of several cables collected in the insulating corrugation. First, a corrugated pipe is placed in the furrow, and then through it the wires stretch to the place where sockets and switches will be installed.

The second laying method is done without the use of the pipe. In this case, the cable in the sede is fixed with gypsum, plaster or putty.

The most convenient way to place sockets is blocks in one frame. They install not only electro.stops, but also connectors for the Internet, phone, cable television.

To stroke holes for sockets, switches or distribution boxes, the methods described above are not suitable. So that all the nests are correct and with even edges, it is necessary to use crops for a peorator with an appropriate diameter. The tool should be used in shock mode.

Tribal without dust

During the repair or when replacing the wiring, you will have to lay strokes or make holes in the walls.

At the same time, a large amount of construction dust settles throughout the room is formed.

To last the wall for wiring without dust, you can use the advice of specialists:

  • Well moisturize the surface on which the channel will be performed for wiring.
  • Use a household vacuum cleaner to capture dust.
  • It is best to take a stroboresis with a special vacuum cleaner connected to it. Then the execution of holes in the walls will take place in a comfortable environment.

There is also such a method of stroke of channels with a corner grinder without dust, like wet cutting of concrete. This method is carried out using a hose that continuously supplies water to the cutting disk and cutting area. You need to be very careful, otherwise the liquid can enter the power tool, which will bring it into disrepair.

After the end of the tableting, the channels should be treated with a primer and fixed in them a cable. Stitch strokes with gypsum, solution or putty mass.

Than stroke the walls

The standard location of lamps or sockets does not always arrange the owner of the apartment. In this case, the question arises of their transfer to another place. To do this, you need to make furrows or holes in the walls or ceiling ceiling. In multi.storey buildings, they are made of concrete or brick. Therefore, if necessary, it is better to take the walls for wiring in advance to avoid a large amount of dust.

You can manually do stroobes in the wall, but if necessary, laying a cable of high length, this will take a lot of time. Therefore, it is better to use the power tool. For work, this kind is used:

The use of the orator has a number of disadvantages. Firstly, the tool produces a lot of noise. Therefore, if work is carried out in a living room of a high.rise building, you will have to negotiate with your neighbors. The process of strokeing by the as a penetrator is quite time.consuming and takes a lot of time. In addition, the resulting depressions have an uneven edge. The traditional “corner grinder” with a diamond circle gives holes with a high.quality edge, but the recesses themselves have an uneven surface. This creates the risk of damage to the wiring, in addition, too much dust is formed in the process.

The ideal option would be a trobrebore. With it, you can quickly and easily make holes and furrows for an electric cable. This tool cuts two discs. They are insulated with a casing that blocks the place of contact with the surface. This makes it possible to break through furrows of different depths. The strobes are smooth inside, and their edges remain even.

In the absence of power tools, you can make a stroke manually. For this purpose, they use a chisel and a hammer. This technique is not suitable for solid materials like silicate brick or concrete. With the help of a chisel, a groove is pierced in the wall, which is then deepened and expanded. The tool is held in the right hand, parallel to the surface, and hit it with a hammer.

How to get rid of dust when touched

Professional builders when laying wiring inside the walls use equipment with a vacuum cleaner. But the cost of such a tool is high and its purchase for a one.time event does not make sense. In order to last a wall with a gateway without additional options, without creating clouds of dust, the masters have to go to different tricks. The simplest method is abundant wetting with water of the processed surface. Small particles can be assembled with a simple domestic vacuum cleaner.

To stroke corner grinding with dust, use the technology of wet concrete cutting. It consists in the continuous supply of water to the cutting disk through the attached hose. You can use the help of an assistant who will simply water the disk and the area of ​​cutting from the plastic capacity. In this case, you should be attentive, the liquid should not fall into the power tool.

The following measures will help reduce the dustiness of the room:

After the strokes are done, the garbage is sweeping with a broom and vacuumed. The recess is treated with soil, laid and fixed the cable. If you need to cut a cable, then use a tool for cutting an armored cable.

The channel is sealed with putty mass, plaster or gypsum.

Electric wires can be drawn without table stroke. This option is attractive to the complete lack of dust. There are many different products in the retail network, allowing not only to disguise open wiring, but also to revive the design of the room. These include:

If there is a need to replace the wiring, without laying a new one, you can use the existing channels.

Small particles of concrete and silicate brick should not fall on mucous membranes or respiratory tract. Therefore, when carrying out work, it is necessary to use protection in the form of glasses and a respirator. If there is furniture in the room, it is also better to close it with a film or cloth.

Useful tips of professionals

If an electric tool is used, it is necessary to work with it without overheating. This can happen if you put pressure on the equipment or work in continuous mode within a few hours. This is especially true for household class devices. But professional counterparts are ready to function without respite to several hours.

Do you always need a stroke

This process can be chosen by those owners of apartments who do not want to engage in a full.fledged repair. The choice of this method is due to the desire to save on building materials and hiring specialists.

Replacing wiring without stroke can be done in the following ways:

In the first case, the wire is placed in skirting boards. In the process of repair, corrugated corps and cable channels are widely used; Install boxes. The wiring in the apartment without stroke can do a specialist for a small fee. But the gasket in the wall of the channels under the electric wire will entail significant financial costs. In addition, you will have to allocate funds for the purchase of finishing materials. The work of professional plastering will also require expenses.

Using old stroke will be a good option if you do not have to change the location of the sockets. In this case, the wiring can be carried out independently.

You can make strokes manually and using equipment. It is best to use a gap with an industrial vacuum cleaner connected to it. The disadvantage of such a device is its high cost, so at home you can use to lay channels with a corner grinder with a diamond disk. Possible wiring without tables of walls. This option will attract many apartments by lack of dust.
