How To: Removing a Load Bearing Wall! (EASY STEP-BY-STEP)
Diamond cutting of concrete openings
Types of diamond cutting of openings:
A gas cutter is used to cut the facade or walls from the outside. This is a petrol-powered hand tool, thus completely autonomous. The design of this tool allows you to cut concrete with diamond saws at any angle, including in hard-to-reach places.
Cutting doorways can be carried out using circular and diamond chain saws. Or, angle grinders equipped with a diamond disc with a diameter not exceeding 400 mm can be used. The hand cutter is used where the cutting depth is not more than 170 mm.
If it is necessary to cut a large number of door and window openings, wall saws are used, which are electric and hydraulic. The diameter of diamond discs on such equipment is 1600 mm, they are capable of cutting to a depth of 700 mm.
for diamond cutting of wall openings
The price of work on cutting or expanding openings depends on a number of factors: on the thickness of the wall in which the opening needs to be made, what material the wall is of, whether the material has reinforcement or not, whether it is necessary to reinforce the opening and some other factors. Price in rubles with VAT 20% for the opening 90 x 210.

Advantages of diamond cutting:
the ability to cut any wall thickness;
the ability to carry out diamond drilling at any angle and at any point;
the possibility of subsequent strengthening of the opening.
What is reinforcement of openings?
A certain margin of safety is laid in reinforced concrete structures, and when using diamond cutting to expand the opening, the wall loses strength, the load on other load-bearing walls and floors changes. It is the reinforcement of the opening that will avoid the occurrence of cracks and collapse.
Before starting dismantling work, a number of preparatory measures should be taken: assess the load on the wall, its role in the bearing capacity of the entire structure; get approval for redevelopment; permission from the fire inspection and finally select the type of reinforcement.
There are several options for reinforcing openings with metal: using a channel, angle or combined. When reinforcing an opening in a brick wall, it is enough to make a so-called groove (a narrow, deep recess) and bring a metal corner under the arch on both sides. When reinforcing walls made of reinforced concrete, use a channel, corner or I-beam. hot-rolled metal profiles that perfectly work both in compression and tension, as well as in torsion and bending, as well as having a fairly comfortable shape and allowing, after dismantling the opening during finishing work, to hide the metal under a layer of plaster or putty.
Reinforcement is required if you are cutting or expanding an opening in a load-bearing wall. details.
Opening making
Although many still say “to punch the opening”, today the impact method of work can be outdated, because the openings are mostly already made using diamond cutting.
The disadvantages of working with a sledgehammer, perforator or jackhammer are primarily related to the shock load on the wall being destroyed. Cracks and chips form in it, impairing the strength of the wall, increasing the corrosion of the reinforcement. Often there is a need to additionally break large and heavy fragments of a destructible wall on the floor for removal from the room. Impact work is accompanied by a lot of noise, but lasts longer.
Punching an opening in a load-bearing wall is really cheaper, but at the same time they forget that after the opening is made by the shock method, inevitable destruction remains that have to be restored. And this is additional funds and time.
We suggest you do it easier. cut an opening in the load-bearing wall using diamond cutting.
Advantages of diamond cutting of openings:
Since the opening to be made reduces the bearing capacity of the wall already in the process of operation, special temporary metal supports are placed under the ceilings. This will make it possible to secure the builders and protect the structure from destruction.
When a part of the load-bearing wall is removed, its strength and load-bearing properties are lost. Reinforcement of the opening in the load-bearing wall is required. The procedure avoids possible deformation and destruction.
There are many typical solutions. Their meaning boils down to increasing the bearing capacity of a weakened wall by introducing metal elements into its composition.
Cutting an opening in a load-bearing wall and its subsequent strengthening is an activity that only certified specialists with SRO approvals can do. It is these specialists and all the necessary professional tools that our company has. We have licenses and guarantees for all types of work.
Opening in the load-bearing wall. where to start work?
During a major overhaul or reconstruction of premises, there is often a need for redevelopment. Quite often, a load-bearing wall becomes an obstacle to this, which is prohibited to demolish. An opening in the load-bearing wall, in the place of which a door or window can be built, partially solves the problem, but it is important to approach such reconstruction correctly so as not to weaken the structure of the house.
It is not allowed to install a doorway in a load-bearing wall without prior approval. This is unsafe and can lead to fines, the need to restore everything as it was.
For approval, it is necessary to have a project for strengthening the opening. It is introduced into the redevelopment project in the form of a special section on the construction and reinforcement of the opening. The opening project contains detailed drawings, reinforcement elements, materials used, the order of work is established.
You can develop and agree on a typical project of the opening, or it is easier to use a standard one, but only having a project in hand, you can proceed directly to work.

Sawing the structure into “fragments” with concrete saws, using diamond tools. called diamond cutting of openings.
DIAMOND CUTTING OF OPENINGS. WORK FOR A PROFESSIONAL
Today, on the market of construction services, any team of workers is ready to undertake work on the manufacture of an opening, using “grinders” and other unacceptable shock-destructive equipment. When using this technique, concrete (reinforced concrete) is able to lose its properties, the connection between reinforcement and concrete is disrupted, microcracks are formed, which leads to a decrease in the overall resistance of the building.
A gross violation of the production technology and deviation from design decisions can create a dangerous situation: an opening in the load-bearing wall made by unqualified “specialists” can lead to sad consequences. Do not trust inexperienced teams and incompetent specialists to carry out the work. It is more difficult and more expensive to fix a defective opening than to make a new one.
HOW WE PERFORM DIAMOND CUTTING OF OPENINGS
Cutting, like diamond drilling for walls, is a versatile and best method to create openings in floors and walls when you need windows, doors and other holes.
When cutting, the falling of concrete fragments on the floor is not allowed. This situation can lead to cracking or collapse of the floor. Therefore, diamond cutting of openings in concrete, in apartment buildings is carried out by us into separate parts, weighing about 40 kg.
ACCURACY AND SAFETY OF WORK
Cutting an opening in a load bearing wall. S.1 Ep.3
According to the requirements of design organizations, we make openings in the walls using diamond cutting. the result is precise dimensions and smooth parts of the concrete without visible chips and cracks.
By using temporary unloading racks in our work, we guarantee the integrity of the walls and floors.
The hand-held concrete machines used by us, such as Husqvarna, Messer, are equipped with a wet cutting kit with low water consumption, which prevents the formation of dust.
Concrete-water sludge is absorbed into a special rag or absorbed by a special mixture, which prevents possible leaks to the lower floors in apartment buildings. In rooms with decoration, it is necessary to paste over the wallpaper, ceiling and nearby objects with foil.
During operation, the resulting noise has an acceptable level. For example. the noise from the hammer drill is much louder.
On average, a standard opening is 2100x900mm, in panels up to 20 cm thick. It is made (cutting) in 1-2 days. We work every day and on weekends, where there are no restrictions.
With years of experience in the industry, our safety standards and work practices will benefit you and your project.
TYPES OF MADE OPENINGS
We offer safe cutting of walls using so-called concrete saws. As a result, the edges remain smooth and do not require any additional processing. To minimize dust formation, water is used to also cool the disc.
We have extensive experience in expanding and cutting new wall openings for doors. You can be sure your doors will be installed correctly and evenly.
As a rule, we manufacture doors in concrete and brick walls, with a thickness of 10.60 cm and more. This is achieved with specialized wall saws that cut the material evenly and achieve precise dimensions.
What openings can we cut?
- doorways in “high-rise buildings”
- openings in individual houses and buildings
- separate entrance to the building
- in the basement, entrance to the basement
- firefighters
- garage doors
- doorways and interior openings in houses, cottages and premises (private and industrial sector)
Please contact our company. your opening must be done correctly the first time!
An opening in the floor, for example for a staircase, may be needed during a new construction or during the renovation of your apartment, building or house.
When converting an attic or basement into a living space, as well as in the process of combining apartments. Horizontal sawing is ideal for creating passages or holes in concrete floors.
These are, as a rule, flat surfaces, such as reinforced concrete floors, floors, pavement, as well as other concrete and asphalt surfaces.
Sometimes replacing old windows may require cutting large holes for more modern windows. In addition, some customers may decide to change the location of the window opening to create a completely new look.
Many older houses have small windows in the basement. They do not let in enough light and they do not allow a person to leave in case of an emergency. Thus, cutting or widening a basement window is a great way to increase the flow of light and to ensure the safety of people in the basement. Cutting a window opening can be done from any side, both from the inside and outside.
Working outside is preferable as the slurry (a mixture of concrete and water) simply sinks into the ground. If cut from the inside. additional costs can often arise in connection with the necessary preparation of the drainage system. Using diamond cutting allows you to create perfect, precise corners, without chips or irregularities. Depending on your needs, our specialists can skillfully expand or cut a new window in reinforced concrete, brickwork, wall panels. A clean cut helps maintain the integrity and appearance of your property.

Sequence of work
Before making holes in the concrete with your own hands, you need to make sure that this does not compromise the strength of the building. Bearing walls can only be cut after consultation with specialists.
Redevelopment works are carried out in the following sequence:
- decide on the size of the opening;
- cover household items with foil;
- dismantle a used door or window;
- wear safety glasses, gloves and a hard hat;
- connect the tool and cut the opening of the given configuration.
The cut edges after diamond cutting are smooth and do not need additional processing.
Redevelopment: Do’s and Don’ts?
When carrying out redevelopment, it is allowed to cut only internal bulkheads and subwindow blocks.
- cut load-bearing supports, walls and beams;
- dismantle ventilation headers;
- brick up the walls with gas risers and wiring;
- increase the utility area at the expense of residential.
How To Remove A Brick Load Bearing Wall. New Opening
All controversial points should be agreed with the operating company.
Reinforcement of openings in load-bearing walls
When cutting walls made of concrete, it is mandatory to strengthen the opening along its entire perimeter.
For this, the following materials are used:
- reinforced concrete lintel laid over the hole;
- welded steel channel structure;
- strapping with a metal corner.
Strengthening work is performed immediately after the removal of the cut segments.
Dust-free cutting feature
Dust-free cutting of partitions is used in the redevelopment of residential premises. All work, as a rule, is carried out with water supply to the cutting edge of the tool. Thanks to this solution, all small concrete particles are bound by the liquid. In addition, overheating of the wheel is prevented and its continuous operation is increased.
Diamond cutting technology involves working on concrete without water supply. Dust collection is carried out using an industrial vacuum cleaner. This approach is used when working in rooms with fine finishing.
Diamond wall cutting technology: advantages and application features
Today, diamond cutting of walls is considered the most advanced technology. With its use, dismantling works, revision of the layout and cutting of openings in the walls of residential and utility premises are carried out. By combining the interior design in various ways, an experienced craftsman can work with material of almost any thickness and strength, regardless of the degree of its reinforcement. Let’s dwell on the features of this technology and the options for using devices of various classes. In the video. work on a load-bearing wall:
Expanding wall openings
Expansion of openings in load-bearing walls is done in cases when it becomes necessary to increase the area of windows or to put a large entrance door. Depending on the thickness of the wall, cutting is done from one or both sides. When performing work on the lower levels of multi-storey buildings, cutting is carried out only after preliminary strengthening of the structure.
Effect of wall thickness
For high performance diamond equipment, wall thickness is irrelevant during operation. Discs and crowns effectively cut openings in any material. The difference lies in the choice of equipment for processing a thin partition and a load-bearing wall. Cutting time is directly proportional to the thickness of the walls with the same quality result.
