Today there are many sources of information on how to properly build a house and make repairs or Finishing work... But sometimes it happens that a person does not need information about a building, but information about the demolition or dismantling of a building. Many people think that a lot of knowledge is not required to demolish a building, but this is not so.
First of all, you need to understand that improper actions during dismantling can pose a threat to health and even human life. In addition, if the building is disassembled correctly, some materials can be preserved intact, which can be reused. High-quality demolition and dismantling of any buildings or walls will be provided by Techno-Digger, whose experience has been confirmed by many years of practice.
Brick building - material features
The most delicate dismantling is considered to be the dismantling of brick buildings. You always want to save a brick for reuse, and it is easily destroyed by powerful mechanical action. For high-quality dismantling of a brick structure, such important details must be taken into account:
- binder that was used in the construction. If the fastening mortar is not very strong, it will be possible to disassemble the building in several bricks, separating them with a metal stake;
- brick quality - if the brick is crumbling, care must be taken not to break it. If it is strong, it will be easier to separate it from each other;
- the volume and peculiarity of the work - if you are going to demolish the building completely, this is easier to do, but if you need to remove only one wall, you must adhere to the rules of caution so as not to violate the integrity of the entire structure;
- place of construction - if the structure is located away from other buildings, it is easier to demolish or dismantle it. And if there are other buildings nearby, you need to make sure that there is no collapse that can destroy them.
Ways to disassemble a brick building
Today, there are several ways to disassemble or demolish a brick building:
- manual is a method of disassembling a building using any available means to separate the brick;
- mechanical - consists in disassembly using different mechanisms and devices;
- subversive - this is the toughest way to demolish or destroy a structure using micro-explosions in certain areas of the building. It is difficult to save materials for reuse during its implementation.
The most important thing when performing dismantling work is to be careful and comply with all safety standards. If there is a need to demolish or dismantle a brick building, it is better to contact specialists, this will help protect yourself and others, as well as save the necessary materials.

Dismantling brick walls with your own hands
When renovating and reconstructing old apartments, dismantling interior walls with partitions are not uncommon. Often, dismantling work is carried out with the aim of competent zoning of rooms. From the outside, the process of demolishing a wall looks easy, but it is not. When performing dismantling work, it is important to take into account many nuances.
Therefore, if there is absolutely no experience in the independent demolition of brick structures, then it is better to entrust this work to specialists. Get more detailed information about dismantling and demolition various designs, for example on the website https://tdigger.ru/ where comprehensive information on this matter is provided.
For the same daredevils who decided to independently dismantle the brick walls in the apartment, it is important to know how to do this correctly.
Before dismantling brick wall, you should make sure that it is not a carrier. As a rule, load-bearing walls are thick and often reinforced from above. monolithic belt... The demolition of such walls is prohibited and can only be carried out after agreement with the appropriate authorities.
If the demolition is subject to the usual internal partition, then its dismantling with your own hands can be done in several ways. The first thing that needs to be determined in this case is the quality of the solution. brickwork... With a poor-quality solution that crumbles even with the slightest impact on it, you can disassemble a brick wall using ordinary scrap.
If, on the contrary, masonry mortar turned out to be of high quality, then you will have to use metal wedges, however, the most best tool in this case, it is a powerful electric rock drill.
So, the quality of the brickwork mortar has been determined, which means that the tool for dismantling the partition has been chosen correctly. The second stage will be preparatory work indoors, before demolishing the wall. This is very important point, which will help to avoid many troubles, such as damage to the floor covering.
Therefore, before dismantling a brick wall, it will be necessary to protect all those surfaces in the room that may suffer as a result. Sturdy plywood or old blankets should be spread on the floor as a last resort. It will not be superfluous to take out all the furniture from the room during the dismantling work.
In addition, the partition itself, which is subject to demolition, will require some preparation. To do this, its surfaces are cleaned of old finishing material, be it wallpaper or regular plaster mortar... Further, all communications, including electrical wiring, are removed from the wall. You should also get rid of the baseboards.
At this point, the stage of preparing the room and the partition itself for demolition is completed, you can proceed to the direct implementation of dismantling work.
Whichever tool is chosen for dismantling a brick wall, it is necessary to start disassembling the structure from the top. To do this, in the place where the wall adjoins the ceiling, the masonry mortar is removed with a perforator from the uppermost row of bricks. After this hard work, the brick can be easily pulled out by hand.
In this case, it is worthwhile to act very carefully so that the wall does not collapse when the top row of bricks adjacent to the ceiling is removed. You should also not knock out more than three bricks at a time if the demolition of the partition is carried out using such a popular tool as a sledgehammer.
Having thus reached the very bottom row, some difficulties may arise, since it is often recessed into the screed. To remove a brick from the screed, it is necessary to rearrange the nozzle in the shape of a peak on the perforator. Having made a groove around the entire perimeter of the partition, the brick can then be quite easily removed from the screed by prying it with a crowbar.
In this article I want to talk about how to correctly disassemble the wall... For what it may be needed at all. Well, let's say you wanted to make some kind of redevelopment in your apartment, private house or office. You want to make one large out of two small rooms, or make a large adjoining bathroom from a separate bathroom and toilet. It is for this purpose that dismantling of partitions.
In this article, we will figure out exactly how disassemble a brick wall. In general, what is the difference between the dismantling of conventional partition walls and the dismantling of load-bearing walls. It differs in that when disassembling an ordinary partition, you do not need to worry that you will violate the integrity of the building, that cracks will go, that the relevant authorities will start making claims to you. You will not need to put capital props in the place of the load-bearing wall. And in general, it is highly discouraged to demolish or in any way move capital bearing walls.
Dismantling brick partitions it is best to start with thorough preparation. Please note that the bricks are quite heavy and when they fall to the floor, your flooring can be very badly damaged. It is good if you are going to completely change the floor and lay new laminate, parquet, linoleum, etc., in which case you don't need to worry. If the coating remains old, then you need to come up with some kind of shock absorption on the floor for the bricks and pieces of plaster. Therefore, in the place of hostilities, you can build heaps of old rags or blankets. There is also nothing to do with furniture near this place, you need to move it away and cover it with a thick oilcloth.
What tool do you need to dismantle:
-
puncher (if any).
Now you can get to work. First you need to do it on the wall that you want to demolish. If you do not want to dismantle the wiring completely, then at least disconnect the wall from the power supply, because the wires may break, or the chisel may directly hit the bare wire. Also, the wall must be periodically moistened to avoid breathing from the resulting dust. And all this with the wiring turned on, one way or another, is unsafe for health.
After that it is necessary to remove all platbands, plinths, both floor and ceiling.
Then you can try, if available. In fact, if everything lends itself easily, then all building materials can be removed in layers: first, remove the wallpaper or paint, then plaster with putty, and only then start disassemble the wall.
The most important task is to knock out the first few bricks. The easiest way to do this is at the top at the junction between the partition and the ceiling with strong blows with a sledgehammer on a chisel. The chisel should be at the junction between adjacent bricks. Thus, you break the bond, the seams crack and the brick falls off. If the partition is laid out on clay, then no problems should arise at all, it rests on "word of honor".
Try to knock out one or two bricks, it is not necessary for half the wall to fall to the floor at once. If a lot of dust appears, then spray everything around with water - this should help.
This is how it is performed dismantling of walls and partitions.
With the aim of expanding useful area premises or its redevelopment, the dismantling of a brick wall is often used. With the right approach to business, you can remove any part of the structure, be it a load-bearing wall or a simple partition. It is also possible to partially dismantle a section of the wall for installation additional door or windows.
But the dismantling of the wall implies the partial or complete destruction of one of the support points of the structure, and therefore entails a certain danger. To avoid the formation of cracks on adjacent walls, or the complete destruction of the building, it is necessary to carry out this procedure extremely carefully, without fail observing all possible rules security.
To dismantle a brick wall, you will need the following tools and devices:
- Heavy hammer
- Sledgehammer
- Chisel
- Special tongs for removing bricks (optional)
- Special supports (for dismantling the load-bearing wall)
- Protective equipment against dust and falling bricks
You should not use cheap and low-quality tools for dismantling. For example, a hammer drill, which is designed to carry small jobs, will not withstand prolonged loads and will not provide sufficient impact force for the destruction of high-quality cement mortar.
Removing any wall should begin with the advice of a specialist. Some walls, especially load-bearing ones, are generally better not to touch if there is no way to really assess the degree of risk. In extreme cases, it is better and safer to entrust the dismantling of such a site to professionals.
All electrical wiring must be removed from the wall immediately prior to disassembly. As a last resort, if the wiring is hidden, and you do not know the system of its location, you can simply de-energize the entire line in the room.
The next step is to provide protection flooring falling bricks can permanently damage it. For this purpose, you can use any springy material, such as pieces of foam rubber or old blankets. If there is furniture in the house, then it is covered with a film to protect it from dust.
If the brickwork is finished with plaster, then it is upholstered. This can be done with a hammer, ax, or other tool.
You should start dismantling a brick wall from the top row. It is knocked out with a puncher or sledgehammer. This should be done very carefully, avoiding large areas of destruction and cracks. Further work on dismantling the brick wall consists in prying each subsequent row with a puncher or hammer blows on a chisel. To speed up the process and more accurate disassembly, experts use special tongs. The principle of using this device is as follows. Several adjacent bricks are clamped with tongs at the same time. Then, using a lever, the clamped bricks are broken out of the masonry. The advantage of this method is that the dismantled bricks do not break when dropped. This makes it possible to reuse them.
If a load-bearing wall is being dismantled, then special supports must first be installed to hold the floor slabs.
A step-by-step dismantling of the bearing wall is also used.
In these cases, part of the masonry is removed from the floor to the floor, then a support is installed in the place of the masonry.
This process is repeated for each safe section. Usually, load-bearing walls are rarely dismantled because of the associated hazard.
But in case of emergency, for example, for overhaul buildings are still practiced.
Sometimes, during the repair process, it is required to disassemble the old brickwork. Disassembly of masonry can be done using various instruments... Using a jackhammer can speed up the process, but in this case the bricks are more likely to be damaged.
In order to disassemble the brickwork you will need:
- a jackhammer with a blade-like working part;
- crowbar or pickaxe;
- chisel;
- hammer or sledgehammer;
- steel wedges;
- respirator;
- gloves.
Begin stripping the brickwork from the top of the wall. Turn on and point the jackhammer at the horizontal seam of the masonry. Throw the broken bricks to the side or slide down along the gutters established for this purpose. Disassemble the masonry in horizontal rows.
Use a crowbar or pickaxe if you do not have a jackhammer, directing the blows of the tool to the places where the masonry is fastened. If necessary, you can clean the bricks from the mortar immediately using the sharp end of a pickaxe.
Disassemble the old masonry with loose bricks using a chisel and a hammer in the same way: in horizontal rows, starting from the top of it. Attaching the chisel to the horizontal seam of the masonry, simply hit it with a hammer. Having disassembled one row of bricks, proceed to another.
Brickwork made on durable cement mortars, disassemble in this way. Hammer in the upper part of the masonry (in several places) steel wedges into the horizontal joints and, if necessary, into the vertical ones. It is more convenient to do this together: one person installs the wedge in the holder and directs it to the seam of the masonry, and the other hits the wedge with a sledgehammer. Then, hitting the horizontal joints between the hammered wedges with a crowbar or a jackhammer, begin to disassemble the masonry, separating the bricks.
If you need to make an opening in a brick load-bearing wall, do so. Mark the position of the opening. Knock out the top brick with a scalpel or sledgehammer, and then nearby. Then proceed to the next horizontal rows. In cases where the masonry of the wall is thick, punch holes first from one side of the wall (half of its thickness), and then from the other.
Disassemble the old brick buildings using technology, if you have the opportunity. Hang a metal core or a blank weighing two to three tons from the crane boom and lower it onto the building from a height until it collapses. Pieces of masonry can then be used for various purposes or broken into separate bricks, clearing them of cement. The integrity of the bricks with this method of disassembling the masonry will be low.
