Strengthening the balcony. Reinforcement of the balcony slab. Varieties of repair of a balcony slab

For many, the decisive argument when choosing an apartment is the presence of a balcony. By its purpose, it is truly universal. After all, this is a convenient place for fans to smoke, and a kind of relaxation area. The balcony can be equipped as a study with an excellent panoramic view, or turn it into a storage room. Well, you should not discount the appearance: other balconies and loggias can be called a real decoration of the house without a stretch.

But nothing lasts forever under the moon. Over time, any architectural structures deteriorate. This is especially true of external, remote, which include balconies. But to prolong their life is quite possible. Especially if in time to detect signs of "aging" and do repairs.

In what cases is a balcony reconstruction necessary?

The vast majority of balconies deteriorate from moisture. Penetrating into the structure, water can cause corrosion of the reinforcement, as a result of which it loses its bearing capacity, expands and actually crumbles concrete.

The onset of the destructive process is indicated by the appearance of cracks. But do not rush to cover them with a solution. First you need to find out how seriously the corrosion has affected the structure.

Cracks can be very deep, which will not be noticeable from the outside. In this case, it is better to entrust the salvation of your balcony to specialist repairmen. And with minor damage you will be able to cope on your own.

The following signs indicate the emergency condition of the balcony and its slab:

bare reinforcement;
the appearance of deep cracks at the junction of the plate with the wall;
destruction of concrete on top of the slab and its detachment from below;
collapse of fragments of the plate.

The strengthening of the balcony slab on the wall structure of the building has its own characteristics and depends on the building material.

How to repair balconies

Restoring a balcony slab involves several work steps. Repair begins with cleaning the balcony: everything superfluous is removed, garbage is removed, crumbled concrete is carefully removed.

The exposed fittings are cleaned of rust. Its upper layer is easily cleaned, and then the reinforcement rods must be treated with a special anti-corrosion agent.

The next stage of restoration is work with a welded reinforcing mesh. It is laid on the surface of the plate and fixed with special dowels so that it is completely recessed in a concrete screed. To do this, a gap is left between the plate and the grid.

A solution of sand and cement is poured onto a reinforcing mesh and “ironized” (the screed is covered with dry cement and rubbed).

The lower surface of the balcony slab must be plastered, pre-treated with a primer.

It is necessary to make sure that the concrete screed is two or more times thicker than the reinforcing mesh.

With significant corrosion of the reinforcing cage, reinforcement of the balcony slab will be required - this is a larger-scale work.

In this situation, rolled steel beams are installed on the sides of the balcony slab and are fixed cantilever to the wall, and the reinforcing mesh is welded to the beams. Next, the concrete pouring work described above begins.

Upon completion of the reconstruction of the balcony slab, its surface must be waterproofed, which is mandatory if the balcony is open. For this, various waterproofing materials of a roll or coating type are suitable. In particular, penetrating waterproofing Penetron has proven itself well. It is applied to a previously wetted surface in two layers, after which the surface must remain moist for three days. In this case, mechanical influences and temperatures below 0 degrees are not allowed.

Features of fixing balcony slabs in houses of various types

People ignorant of construction believe that a balcony slab is a ledge of a floor slab. But this is not so.

Such a design would shorten the life of not only the balcony, but the whole house: corrosion of the reinforcement will penetrate deep into the slab, and the ceiling will lose strength, which threatens the house with an emergency condition and ultimately demolition.

If you let the balcony slab through the wall, the area of \u200b\u200bthe support will be larger, however, building structures can not withstand long multidirectional loads. If the balcony slab passes through the wall, its inner edge will press on the latter, which can lead to sudden catastrophic destruction of part of the structure.

Currently, the following effective and safe methods of fixing balcony slabs are used:

clamping or pinching in the structure of the exterior wall of the building;
the use of a cantilever slab;
support on the console of columns or internal walls (in frame buildings);
suspension to internal load-bearing transverse walls or to the ceiling;
reliance on attached reinforced concrete, steel or wooden structures.

In brick buildings:

strengthening of the balcony slab is carried out by pinching. Reinforced concrete overhead and lining elements, which form a niche for a balcony slab, are walled up in the outer wall of the building. The edge of the slab adjacent to the outer wall is sure to thicken. The entry of the balcony slab into the wall is quite large. The plate is necessarily welded using steel anchors.

In houses of reinforced concrete and panel and type:

balcony slabs are based on reinforced concrete structures with the use of ceilings. The strengthening of the balcony slab in frame buildings is carried out using beam technology. In this case, there is no load on the wall of the building, since the balcony slab rests on the column consoles.

Installation of balcony fences

Despite the fact that the old fence can still be strong enough, the overhaul of the balcony slab already implies the installation of a new enclosing structure. In addition, if in the future it is planned to glaze the balcony and warm it, then it will not be superfluous to think over a quality basis in advance.

When fencing, welding is usually used.An alternative way is to fix the structure with anchors.

The frame of the new fence is made of a rectangular profile pipe. This design is easy to install and has a very attractive appearance. “In the appendage” a galvanized steel casting is attached to it along the entire perimeter of the balcony slab, which reliably protects its edge from rain and snow.

Balcony slabs wear out for natural reasons

Factors affecting the wear of a balcony slab

For all my many years of experience in the field of repair services, most often I had to deal with the repair of balconies in old buildings. Dealing with the problem of painting walls or windows is not difficult, but balcony slabs will bring much more trouble. I can say that the rapid wear and destruction of balcony slabs is primarily affected by improper operation, natural precipitation and temperature fluctuations, as well as their combination with dubious installation and materials of inadequate quality. Do not leave noticed cracks or other damage by gravity, because in the future this can lead to the complete destruction of the balcony.

Open balconies require more care

At the first “calls” it is better to make minor repairs with your own hands than to overhaul with the help of professionals, various equipment and large financial investments.

Open balconies require more attention to care, because they are more exposed to destructive factors.

Damage Detection Actions

Do not leave noticed cracks or other damage by gravity

If you find serious damage on the balcony or the outside or back side, I advise you to immediately write a statement to the management company, housing and communal services and involve specialists for a qualified examination of the external and internal structural elements. The expert opinion is the basis (document) for the repair, and will also show how serious the wear of the slab and the balcony as a whole.

This is the first thing to do, while attaching a photo of the destruction of the plate and the signatures of the neighbors. This primarily relieves you of liability for damage to property or personal injury if parts of the concrete structure fall. But this is only if you will not use the balcony further, after the conclusion and the ban on the use of the emergency balcony by a special commission. Although the stove must be repaired by the housing and utilities sector or by the management company, I really do not recommend you to hope so much. Due to inaccuracies in regulatory documents, these organizations will simply refuse you this, arguing that they lack funds. So do not waste precious time on empty waiting, but do the repair of the balcony slab with your own efforts, because it is faster and better.

At the first "calls" it is better to make minor repairs yourself

Collect all the checks for the purchased materials, and if you used the services of repairing a third-party organization, then an agreement with them. By submitting these documents in court, you will have a chance to receive compensation for the money spent.

Balcony slabs are not very easy to determine the extent of destruction. Under an external small crack, I repeatedly had to deal with voids or through cracks. Therefore, take a preliminary examination very seriously. To get started, free the balcony from objects stored there, debris and dust, inspect the cracks. Using a metal probe, you can check the depth of cracks, and with a hammer, the presence of voids inside and remove the upper layer of a weak solution. Take a close look at the presence of fungus and exposed rusting parts of metal structures. After the inspection, you can already conclude which type of repair you need.

Types of repair of balcony slabs

There are three main types of repair of balcony slabs:

Small;
Average;
Capital.

Repair is different

Minor repairs

If during the inspection of the balcony slabs you notice minor cracks and grooves, then to repair such defects it will be enough for you to carry out minor repairs. To do this, thoroughly clean the balcony from dust and dirt, apply a primer, and on top a cement screed made by yourself. For these purposes, you can also use a building mixture on an adhesive basis, applied depending on the damage in 2-3 layers. For minor repairs, laying ceramic tiles is also suitable.

Concrete screed balcony slab

Medium Repair

Medium repairs will be more costly in terms of time and material investment. It consists in the dismantling of the upper layer and waterproofing, the complete restoration of unsuitable layers. When pouring a new screed, it is necessary to ensure a slope of the plate by 2-3% for water drainage. To do this, make the layer thicker near the wall, and with the help of the level we control the desired degree of inclination. We make a screed about 4-4.5 cm from cement and sand in a ratio of 3: 2, it should be quite thick and not spread. After the screed has dried, it is possible to make a waterproofing, for example, liquid or dry compounds on a polymer-cement or cement basis can be used. At the same time, it will not be amiss to check the metal frame, if there are no signs of damage and rust on it, then no action should be taken with it.

Medium repairs will be more expensive in terms of time and material investment

In order to make minor or medium repairs, there must be a minimum set of tools and materials:

master OK,
level,
grater,
reiki
formwork boards,
primer,
construction mixer
sand and cement
waterproofing materials
hammer,
metal probe.

Overhaul

Overhaul is necessary in case of emergency condition of the stove

The need to repair the balcony is overwhelming when all the components of the balcony structure are brought to an emergency state, namely:

The balcony sloped noticeably (more than the permissible norm of 3%);
Destroyed or crumbled top layer of concrete;
A rusty reinforced mesh is visible;
Collapse of the concrete parts of the slab;
Deep gaps in the plate at the junction with the wall;
Shattered balcony railing.

To make it possible to repair the plate overhaul, in addition to tools and materials for small and medium repairs, I also recommend depending on the work being carried out: a metal cable and corners, electric welding, electrodes, electric drill, reinforcement and reinforcing mesh, shovel, iron brush, anti-corrosion primer, etc. .

Ways to strengthen balcony slabs

If the balcony is tilted more than the permissible norm, then it must first be strengthened. To strengthen the balconies on the lower floors, a columnar foundation can be used. For this, a concrete platform is poured under the balcony, and metal poles 10-15 cm in diameter are installed on it, each of them must support the slab. If the balcony is on the top floor or it is impossible to establish a column foundation for any other reasons, then to strengthen the slab you will have to mount brackets or mensols. The upper reinforcement of the slab can also be performed using a metal cable, which is attached to the sides of the balcony with anchors, the joint between the slab and the wall in this case is further pulled together by the corners.

Repair emergency balcony

If the top layer of concrete is destroyed, and the metal frame is exposed and corroded, then I advise you to clean such parts of the rods with a metal brush and treat it with an anti-corrosion primer. You can also weld part of damaged metal rods. If damage by corrosion is more widespread, then the metal frame should be completely welded again. It must be fixed with special dowels, leaving a small space between the plate and the frame for the solution. Next, formwork is done from the boards so that the solution does not leak out of the balcony. It should be remembered that the concrete layer should be 2-3 times thicker than the metal frame.

Slab insulation

After the screed has dried, it is necessary to carry out waterproofing and sealing, this can be done using such materials:

Lubricating elastic - made on the basis of bitumen and used for roll roofing;
Rolled - on a bitumen basis, such as glassine and ruberoid;
Polymer - based on polyurethane, are mounting foams and compounds for sealing.

Do-it-yourself balcony sealing

It is also necessary to take into account that a specialist in this field should overhaul a balcony slab.

The best option would be to conclude an overhaul agreement with an organization that has rights to these types of work.

Thus, you will have a guarantee on the work performed and will not be held responsible.

If you still want to do it yourself, be sure to invite a specialist to assess the degree of damage professionally, as a result, it will turn out cheaper than eliminating the consequences of accidents.

Sometimes you get an apartment in a very solid house, but the condition of the balcony is horrifying. If it is not emergency, then in this state it cannot be used, and it needs reconstruction. If you are confident in your strengths and abilities, you can do the work yourself.

Many people mistakenly believe that a balcony slab is a ledge of a floor slab. But this is not so, there are many ways to fix the plate. And to know how the plate is fixed, in each case it is necessary.

Ways of fixing a balcony slab:

A cantilever slab is used;
Pinched or clamped in the structure of the external wall of the building;
Suspension of the slab to the internal transverse bearing shutters or to the ceiling;
Support on the console of internal walls or console of columns;
Reliance on steel, attached reinforced concrete or wooden structures.

In a brick house, reinforcing a balcony slab provides a pinch method. In a panel house, balcony slabs are supported on reinforced concrete structures using floors. And in frame buildings, the balcony slab is strengthened by beam technology.

By the way, many people think why the design cannot be solid, so that the floor slab is made immediately with a ledge under the balcony. But this method automatically reduces the life of the building as a whole. Because this is fraught with corrosion of reinforcement penetrating deep into the slab, and the overlap will lose strength.

When repairs are needed: strengthening the balcony

How exactly is the balcony slab destroyed, and whether it needs to be strengthened, can only be determined by a specialist. Assess all sorts of defects should professionals. But the need for major repairs, of course, is immediately visible.

Types of repair of balcony slabs:

Minor repairs;
Average;
Emergency;
Capital.

An article about repairing a loggia may also be useful to you:. This is a very painstaking business requiring thorough preparation.

If you see cracks on the surface of the plate, do not rush to purchase the appropriate materials and cover them with a solution. First of all, it is necessary to find out what is the degree of corrosion of the destruction of the reinforcement. Sometimes from the outside it is not visible how deep the cracks are. If they are not deep, then minor repairs and medium repairs can be done with your own hands.

Balcony emergency condition or balcony replacement

How to understand whether the emergency condition of the balcony, what this definition implies? Once again, it is worth repeating that professionals should evaluate destruction. But you can pre-inspect the balcony and see what kind of restoration is needed.

The emergency condition is determined by the following symptoms:

Armature is bare;
Quite deep cracks appeared at the junction of the plate with the wall;
Concrete collapses on top of the slab, and on the bottom of the slab it delaminates;
Fragments of the plate are falling off.

Of course, in this case you cannot touch the device yourself. A team of installers and special equipment is called up (possibly not one unit). Usually, such a plate can no longer be strengthened, it must be broken out of the bearing wall.

Problematic question: who should repair a balcony in a privatized apartment

It is worth saying that often this topic really becomes problematic. Due to the confusion in the legislation, these questions arise. According to the rules, the management company must repair the balcony slab. And here, lattices, parapet - the owner of the housing is already responsible for this.

But disputes still arise. And here you can’t pull, if you see that the condition of the balcony is in emergency, and the company is not eager to help with the repair, write a statement (and not one) to other controlling authorities. Time is working against you, and if disputes and litigations drag out, you may have to repair the stove at your own expense.

If you live in an apartment building where there is more than one such balcony, act together. Look for a sample statement, check whether they answered you on time. Sometimes the problem is solved very quickly, and sometimes it’s like a series, a series of proceedings after a series. Strive for the truth, because this is, above all, a security issue.

Stages: restoration of the balcony slab

Moisture is the main cause of damage to balcony slabs. Inside the stove, water can become an activator of corrosion of the reinforcement. If we are talking about the old Khrushchev, for example, the protection of concrete from moisture is reduced, and water easily flows to the reinforcement. And such reinforcement logically loses its bearing capacity, which means it expands and the balcony collapses.

Stages of restoration of a balcony slab:

It is necessary to clean the balcony, take out all the excess, remove rubbish, remove crumbled concrete;
The fittings need to be cleaned of rust; today there are a lot of special tools on sale;
The welded reinforcing mesh must be laid on the surface of the plate, fixed with special dowels (it must be recessed in a concrete screed);
Next is the fastening of boards for formwork around the perimeter;
A solution of sand and cement is poured onto the reinforcing mesh, followed by “ironization”;
Next, you need to plaster the bottom surface of the plate, only first treat it with a primer.

An important point - the thickness of the concrete screed should be two or more than three times the thickness of the reinforcing mesh.

When the reinforcement of the plate is completed, its surface is necessarily covered by a layer of waterproofing. If the balcony is not burdened with glazing yet, this moment is mandatory (so as not to complain later that the balcony is leaking). It can be rolled or coated.

Reinforced balcony slab reinforcement

There is an important detail - the floor slabs, which are based on fences, have a tensile zone in the lower part, which is why reinforced reinforcement is attached there. But the balcony slab is cantilevered, the stretch zone is already at the top, therefore, the upper zone requires reinforced reinforcement. This is a fundamental point.

Therefore, the location of reinforcement reinforcement is necessarily changed if the balcony slab is poured. If necessary, the balcony slab is made not cantilevered, but with the necessary supports on pillars of steel, reinforced concrete, brick, etc.

Thermally separate the balcony slab from the floor slab. Otherwise, it will turn into a through path of cold. Any modern heat-insulating element, the installation of which you will master, will help in this.

Competent restoration of the balcony (video)

Repair and restoration of balconies is often exclusively professional business. It is one thing if you decide to tint the lattice of a metal fence, another - if the balcony slab itself needs repair. The right decisions!

Strengthening the parapet of the loggia is a very important stage if a decision is made on glazing. Almost all double-glazed windows have significant weight, and the fence serves as a kind of foundation, in fact, the foundation of the window. That is why it must be very reliable and as strong as possible.

The technical condition of the balcony should be assessed at the stage of preparation for glazing.

If the assessment is carried out incorrectly, the loggia may not be able to withstand the load created by the double-glazed windows.

It is necessary to test the level of disrepair, design features, the quality of the materials that were used during construction and a number of other factors.

We strengthen the parapet of the loggia and balcony with foam blocks

Independent strengthening of the parapet of the balcony should not be done if during the inspection it was found that the fence is in critical condition. In this case, the work should be performed by professional builders or people with good construction skills. Do-it-yourself strengthening is carried out only in new homes where the parapets are relatively strong.

Foam blocks can withstand heavy loads

The strengthening of balconies with foam blocks is carried out precisely on balconies that can not withstand a brick structure. Foam blocks are a versatile building material with excellent properties.

They are able to withstand a significant load, as well as retain heat. In fact, the use of such material allows you to combine the strengthening of the parapet and its insulation.

It is worth noting such advantages of foam blocks as environmental cleanliness, durability, as well as exceptional strength.

This alone makes the material an excellent option for use.

Speaking of the many advantages, one cannot but mention a small drawback. We are talking about low indicators of resistance to moisture. This leads to the fact that it is necessary to attend to additional protection against moisture. For this, a decorative waterproofing layer is used for decorative finishing. The role of finishing can be played by siding or galvanized metal. All information about siding trim you can find.

Independent work is carried out in a certain order. Mandatory calculation of the height of the parapet and window opening is initially carried out. After that, prepare the balcony for installation work. It is also cleaned of debris. Next, insulation is laid on the balcony slab.

Further - one of the most difficult moments from the technical side. Using the level and plumb, the foam blocks should be laid around the outside perimeter of the balcony. For strengthening, a masonry mortar or a special mixture based on glue is used. Then it is necessary to hammer the reinforcing bars in the places where the masonry and the wall are connected.

Photo instruction

The calculations are carried out in such a way that the ends of the reinforcement, which remained free, fit into the length of the seam of the masonry of foam concrete blocks.

The next stage is the reinforcement of the entire masonry using a galvanized metal mesh with diameters of 3 millimeters. The foam blocks themselves are covered with a special primer designed specifically for foam concrete. Then, on the outside, it is necessary to have improved adhesion characteristics.

And the last stage is the decoration of pre-selected building materials from the outside. As mentioned earlier, the best option is a galvanized steel sheet or siding, which will give the balcony a very modern look and also protect it from the negative effects of the environment.

Training video:

After the parapet was reinforced with foam blocks, it will be necessary to warm it, otherwise there will be no need for glazing.

The classic version of insulation is the insulation of the entire balcony.

Any non-combustible materials with sufficient heat and moisture insulation characteristics can be used, but they are very thin and light. It is very important that their installation can be carried out independently.

Metal parapet reinforcement

The reinforcement of the parapet with metal implies that the fence will be completely replaced or reinforced.

Steel corners can also be used as material, which will need to be welded.

Any of the options is ideal even for very shabby structures.

There is also a universal method of strengthening with metal - this is the construction of a special welded structure. She will tie the old parapet. It is attached directly to the wall of the house.

Any of the methods of strengthening with the help of metal structures involves the transfer of the main load from the glazing of the balcony to the fence.

The principle of transferring the load not only to the stove, but also to the wall of the balcony is a very reliable option, even if the condition of the balcony is rated “satisfactory” or lower. Welding of the fence must be done on site. Metal stakes and channels are used.

Important to rememberthat, according to the requirements, the height of the balcony railing must be equal to or higher than 1.2 meters. More information about the railing is written.

And this applies not only to open balconies, but to balconies, as well as loggias with glazing.

It is desirable to use stainless steel as the material. It is immune to corrosion and also has significant strength and durability. If an open balcony is preferable, then the stainless steel will look great on the facades of modern houses.

The best option is a forged metal parapet.

The possibilities of decor in this case are truly unlimited. It is possible to engage in the installation of forged railings independently, it is very important to produce the most accurate dimensions before ordering fences.

Strengthening the parapet of the balcony before glazing:

Installation of open railings is carried out using channels and anchors. As for the base, it can be further strengthened with cement masonry.

Metal reinforcement is a versatile and very common method suitable for any balcony.

For insulation, the same lightweight materials are used, which are used in the case of foam concrete blocks.

With the arrival of warm spring days, many residents face the question - is it time to repair the balcony. And not only . Sometimes a balcony or loggia brought almost to an emergency state.

Repair of such structures is a very serious issue and requires a competent approach to its solution. and you will give a fresh look, but do not add strength to your loggia. Be sure to have to conduct a survey of the balcony and restore its base plate, possibly with reinforcement.

And what can happen if timely repairs to the balcony are not done? The photo below shows a sad ending.

Collapse of the emergency balcony

How to make a balcony repair yourself

To avoid the sad outcome described above, it is necessary to constantly monitor the state of the entire structure. Overhaul is quite possible to carry out independently.

Let's look at how to make a balcony repair yourself in stages.

The first thing you should do is to carefully examine the condition of the base plate of the balcony, parapet. What should I look for?

Strong destruction, bare reinforcement.
The slope of the base plate.

Base plate restoration

Where to start repairing a balcony? After a visual inspection, we make a list of what damage was discovered, whether it is possible to do it yourself. If you find very severe damage, you can contact the management company.

According to the Decree of the Government of the Russian Federation No. 491 dated 08/13/2006, according to the Rules for the maintenance of common property, it consists of balcony slabs and load-bearing walls in an apartment building. Consequently, the overhaul of emergency balconies must be done by the management company.

But in order for these works to be completed, the balcony must be considered emergency. To do this, you need to write a letter to the director of the management company with a request to repair the balcony structure with photos attached.

Attention: enclose statements from neighbors requesting to protect them from damage in the event of a balcony collapse.

After reviewing your application, it will be decided at whose expense the restoration of the structure will be carried out. If the resolution of the issue is delayed, you can repair the balcony yourself and, with the submitted estimate, turn to the courts for help.

We will not dwell on this version of the solution to our problem. Let's do the repair work ourselves.

The base plate can be destroyed very much. In this case, it will have to be strengthened.

A slab of a small balcony requiring restoration

To do this, remove the waterproofing layer, clean the surface of the plate and, if necessary, make notches on it. Wet the stove with water.

With a small degree of damage, reinforcing with a metal mesh filled with expanded clay concrete mortar is sufficient. It is necessary that the thickness of the grid is located in the middle of the poured solution.

Restoration of a balcony slab

With large damages and partial destruction of the reinforcement, it will be necessary to strengthen the plate in a more complex and time-consuming way.

After preliminary cleaning of the slab, we lay out the reinforcing mesh and make a concrete screed on top of it, covering all the defects. If you have bent over the balcony more than the permissible 10˚- you need to align with an additional screed.

Do not forget that all work performed increases the weight of the stove. In order not to collapse the balcony - its fastening should be strengthened.

One of the types of balcony reinforcement is channeling with a channel

With a strong destruction of the reinforcing base, the reinforcement of the balconies is carried out by installing additional cantilevered beams.

Base plate on cantilever beams

On a note: standard reinforced concrete beams are used for reinforcement. If this is not possible, they can be replaced by an I-beam or a channel.

Reinforcement is also used when expanding the area of \u200b\u200bthe slab during repair. In this case, it is possible to apply extensions that hold the carrier plate tied with channels, as shown in the diagram and in the photo below.

One of the options for strengthening the base plate

Strengthening the carrier plate during its expansion

Wooden balconies can be strengthened with lower struts during their repair. It is preferable to use aluminum - lighter with sufficient strength and having a beautiful appearance.

By the way: firms manufacturing cast and forged parapets for balconies can make beautiful struts according to the sketch of the customer.

Beautiful struts at the wooden balcony

How to make repairs on the balcony in Khrushchev

With great attention, it is necessary to approach the repair of a balcony in Khrushchev. The fact is that the houses of the old project have light open balconies. It is undesirable to overload them with additional reinforcing materials. The maximum load over the entire area of \u200b\u200bthe balcony should not exceed 200 kg / m 2, the strip load on the section 0.8 m wide along the railing - 400 kg / m 2 (SNiP 2.01.07-85). What weight the balcony can withstand is easy to calculate, knowing these requirements.

Therefore, after strengthening the base plate, while redecorating the balcony in Khrushchev, apply lighter materials (do not stop at a traditional heavy lining), apply. Before again, recount how many kilograms the frames with double-glazed windows will weigh, whether the total weight will exceed the permissible load.

Parapet repair, elimination of crevices

When repairing the parapet, we pay attention to its deterioration and the presence of damage.

In case of severe damage, it is possible to completely replace the parapet with a new one made of lightweight foam blocks with reinforcement with a metal mesh. We replace the metal parapet without changing the design.

In case of minor damage, we carry out local repair of surfaces, sealing cracks and crevices. How to cover non-through cracks? Germoplast or Emphi polyurethane sealant can be used.

How to close the cracks on the balcony is shown in the figure below. The metal sheet is used to protect the mounting foam from direct sunlight, from the impact of which the foam is destroyed.

Sealing gaps between the parapet and balcony slab

Continuation of repair after strengthening the balcony

Overhaul is not only to strengthen the balcony slab. No less responsible work -, and.

Let's do a quick review of the above works.

For it is preferable to use metal-plastic frames with double-circuit double-glazed windows. They have good sound and heat insulation properties.

Do not forget about the so-called. seasonal backlash. It is present in glazing with a width of more than 3-4 meters. With seasonal play, gaps will be formed between the double-glazed windows. It is necessary to restore the sealing of the glazing.

Spend on all types of balconies and loggias using the same technology. We will not consider these operations in detail - information about them can be read by clicking on. Do it especially carefully - otherwise you will later observe how water flows from the ceiling.

When repairing a balcony in a prefabricated house, it must be borne in mind that it needs more than, for example, a brick house. This is due to the higher thermal conductivity of the panels.

The most common during repairs is extruded polystyrene foam. The sealing of the seams between the sheets is made by mounting foam.

DIY loggia repair (insulation)

You can choose from mounted or freestanding oil coolers. But the infrared film heat-insulated floor will be the most effective and economical.

Depends on your taste. yourself or found on the Internet.

Conclusion

We examined how to repair the balcony yourself. What issues should be addressed with greater responsibility. How to distribute the load on the plate.

To visually see the difference in the balcony before and after the repair, we offer you two photos below.

Finally, look at the balcony repair. The video was shot in a rather interesting style.
