Sealing in panel houses with cosmetic repairs, it is unlikely to solve all problems. At the moment, this is the most inexpensive way, but you need to use it only when there is no serious damage.

First, an examination is carried out and an assessment of the condition of the seams is made, and only then an action plan is drawn up and a solution is chosen. If, during construction, the installation and sealing of butt joints in the panel building was done well and now there is minor damage, then you can resort to cosmetic repairs.

Sequence of work:

• The damaged joints between the panels are thoroughly cleaned of old material and dirt.
• Then the surface is treated with soil-impregnation deep penetration... It is important to carry out this work with great responsibility, since the quality of the termination depends on it.
• The inner space of the joint is filled with heat-insulating material and covered with a plaster compound.
• After that, a mastic is applied to the surface for sealing, which protects the repaired area from the destructive effects of moisture. It is recommended not to skimp on this material, since using cheap mastic it is impossible to avoid repeated repairs in the near future.

Because redecorating considered quite primitive, it is necessary to focus on the quality of the materials used. This somehow guarantees a good durability of sealing the joints of external walls.

Local repair

The procedure for arranging interpanel seams during local repair is as follows:

1. As with any type of repair, sealing work begins with an inspection of the damage. They identify foci with severe surface defects and proceed with repairs.
2. The crumbling and cracking cement is removed with a construction trowel.
3. Then, at a distance of about 2 cm from each other, holes are drilled using a perforator, which are filled with polyurethane foam. The better the voids are filled, the more airtight the seam will be.
4. Extra parts polyurethane foam cut off construction knife, after which the surface is primed and covered with a layer of plaster.
5. The sealing of seams in panel houses ends with the application of mastic.

This method of local repair provides not only good waterproofing but also thermal insulation. In some cases, it is advisable to use a sealant instead of polyurethane foam.

In the same way, the pipe on the roof is sealed or the joints between the floor slabs are sealed.

"Warm seam"

This technology for sealing interpanel seams is considered the most effective. The cost of the work depends on the length of the damaged areas and usually greatly exceeds the cost of cosmetic repairs.

The sequence of actions for the "warm seam" technology:

• The joints between the panels are fully opened. Unlike local repairs, here work is done along the entire length.
• The old thermal insulation material is completely removed.
• The damaged sections of the panels must be repaired, cracks and chips must be repaired.
• The inner surface is treated with soil impregnation. It penetrates deep into the pores and prepares the seam for sealing.
• The seam is filled with a small amount of construction foam, since it has good thermal insulation properties and, expanding, does not leave voids. When doing this work, you need to be careful that the foam does not get on the skin or eyes.
• Without waiting for the foam to increase in volume, start styling thermal insulation material(foamed polyethylene). Thus, the construction foam will remain inside the joint, filling all gaps and voids.
• After that, they begin to apply mastic for finishing the seams. It is important not to leave areas uncovered with mastic, as in this case moisture can get inside the seam and destroy it.

In a similar way, windows are sealed from the street side, as well as roof sealing. The technology "warm seam" is able to provide a home for many years reliable protection from moisture penetrating into the joints between the panels.

Despite more high price embeddings using this technique, you will save a lot of money, since you will need the nearest repair no earlier than in 10-15 years.

Sealing interpanel seams is one of the most important construction operations, because it is the joints that represent the weakest point. In addition, over time, defects may appear in them, and then, at the request of residents and the housing maintenance organization, re-processing is carried out.

Why process seams in a panel house?

Sealing of interpanel joints is the process of filling the voids formed between the slabs. If this procedure is ignored, then moisture, cold air will penetrate through the cracks, and condensation will form. By eliminating such defects, you will not only insulate the room, but will not allow dampness and mold to get into the house. And the latter is very harmful to our health. In addition, wallpaper peeling, walls blackening and other troubles are possible, so the aesthetic side will also suffer.

Sealing is done not only at the construction stage, it is necessary to periodically restore the joints.

What are the causes of leakage? First of all, errors in design and construction itself. It is also very important to choose the right materials. For example, a combination of seals with varying degrees elasticity will not give the desired result. If you decide to use special self-adhesive tapes, then you should not give tension, it is better when they sag a little. Plus, an additional adhesive sublayer should be applied from below. This will keep the stress inside the sealing material to a minimum.

Foam, mastic, tape - exploring the variety of materials

Today there are many sealants for interpanel seams, and they have different kind... Special mastics, silicones, etc. are very popular. The choice of this or that material depends on the width of the cavity. If the seam is narrow, then silicones should be preferred, but wider and deeper grooves are treated with polyurethane foam. It is best to use non-flared, otherwise you will have to trim off the protruding parts. And this is already extra labor costs, and it is not always easy to make such a step, especially if it comes about outdoor work on the upper floors.

In addition, the foam is afraid of ultraviolet rays, so it must be closed, the finishing layer must be in the same plane with the plates, that is, the frozen composition will need to be cut out with a small depression. Expanding material should only be used when working with very large seams. In this case, it is applied in two layers.

Special sealing tapes have also found their application. It is advisable to use them even at the construction stage. The technology is simple - they lay a strip of sealant on the joint of concrete elements, and under the force of the pressure of the upper part, the material is pressed and the connection is reliable. Now you can not be afraid of either drafts, or precipitation, or other vagaries of the weather.

Features of sealing technology

The secondary sealing technology differs depending on the condition of the joints. If they do not have significant defects and the mastic has retained its properties, then it is quite enough to simply replace the outer layer. But when the joint is severely destroyed, then all old materials should be completely removed and replaced with new ones.

Carrying out such work, you should adhere to some rules. In the event of defects in horizontal joints, seams of at least three vertical rows must be treated with a sealant. If the integrity of the vertical seam of the longitudinal facade in the house is violated, then all vertical cracks and adjacent horizontal ones will have to be repaired. And when it is necessary to carry out restoration work from the end side, do not forget about all the joints between the longitudinal walls and end panels, as well as the entire facade.

In addition, the mastic must be flexible enough, because interpanel seams in a house can change their size somewhat due to shrinkage, concrete creep, thermal expansion, or under the influence of various loads... If the material is too hard, then depressurization will occur and restoration work will have to be carried out again. Also, the mastic should fit into a layer at least 2 times thinner than the joint, at least for gaps with a mouth of more than 1 cm.

We close the seams in the house on our own

Now it's time to study the technology of sealing interpanel seams. Let's try to compose an instruction that is understandable even for "dummies", although it should be noted that professionals should be engaged in such work. First, they have special equipment to work at height. Secondly, our comfort and economy depend on quality, since the room will release less heat in winter, and even health, because the negative effect of fungi and mold on the human body has long been proven.

How to seal the seams in the house on your own - step by step diagram

Step 1: preparation

In order for the sealing of interpanel seams to proceed as efficiently as possible, the entire necessary inventory... It will come in handy for us metal brush, spatula, vacuum cleaner, sponge, shovel, broom. From the material you need to purchase the sealant itself, insulation, foam, sand and cement. Next, it is very important to prepare the room. All furniture, if we are talking about a residential building, or other items are taken out so that the room is empty. Then the old covering should be removed from the walls, so we free up access to the seams.

After removing large elements, we clean the room from dust, in this case a vacuum cleaner will come in handy. We carefully go through all the joints. If we are talking about the secondary sealing of panel seams, then we remove from them and old stuff... Do not forget to carry out wet cleaning after that, otherwise dust from the air will settle in the most inappropriate places and this will negatively affect the quality of work. Then we wait until the surface to be treated is dry, and then we degrease it with a special agent.

Step 2: Warming

The key to success is high-quality insulation cavity. If the seams are large enough, they are first filled with polyurethane foam. Until it has completely hardened, a layer of thermal insulation is laid, which most often looks like a very dense hollow tube. Thanks to its excellent elasticity, there will be no installation problems.

There is another sealing scheme, "warm seam". In this case, the insulation is laid first and only then it is foamed. Thanks to this combination, the cavities are reliably filled, and drafts, and even more moisture, have no chance to penetrate the room. If suddenly you have acquired an unsuitable foam or applied too much, then the excess should be removed. In this case, the gap should be such that the mastic and the topcoat will fit into it.

To protect the seam from negative impact the environment if we are talking about outdoor work, it is necessary to process it additionally cement-sand mortar... But only after the mastic has completely solidified. Inside the room, the walls are usually plastered, and a special mesh is applied to the joints. Moreover, it is better not to save on the latter, otherwise cracks will form on the plaster. In principle, the sealing of interpanel seams is carried out in approximately the same way when using any of the materials. However, do not forget to read the instructions on the packaging, you can also find a lot in it. useful information.

Sealing joints in panel houses.

We offer comprehensive protection your apartment from freezing in winter period:

2. Sealing and insulation of cracks and joints glazed balconies, loggias.
3. Installation of a roof over a balcony or loggia, followed by sealing of joints and insulation.
Modern materials to seal the interpanel seams, they withstand temperatures from +50 to -50 degrees Celsius. If the distance between the panels is too large and the sealant does not hold, the seam is sealed by laying a seal (velatherm). Also used in sealing interpanel seams construction foam filling in all the voids between the panels. And then at the final stage of sealing the interpanel seams, the sealed joint is covered with a sealant. There are signs by which you can determine whether your building needs sealing of interpanel seams. The main ones are freezing, wall dampness, drafts. Sealing of interpanel seams can be carried out at negative temperatures, but not in wet weather. In winter, water freezes in the interpanel seams and cracks in the facade, and this leads to the expansion of cracks and seams and the destruction of the wall. It is no secret that ice has the power to destroy metal structures, concrete, stone and other materials. Water penetrates the walls of the facade through and through, and turning into ice expands the material, which leads to the destruction of the building. Do not over-tighten the interpanel joints and you will extend the life of your building.

The cost of sealing interpanel seams.

The minimum order is 10,000 rubles. (about 30 running meters.)

E) Full autopsy (removal of old sealant and insulation) - 600 rubles.

Sealing and sealing interpanel seams and joints is a responsible job, like all construction work. All high-altitude joint sealing works are carried out using the industrial mountaineering method. There are many factors that affect the quality of the sealing of seams and joints. It is necessary to choose the right materials for the work performed to seal seams and joints. Depending on the grade of concrete of the wall, from the year of construction of the building, this or that sealant can serve in different ways. The customer is, of course, interested in the long service life of the walls of his building. Correctly chosen technology of sealing seams and joints, correctly selected materials and professionalism of employees are the necessary factors for high-quality work performed.

The technology of sealing interpanel seams and joints.
There are two main methods of warming and sealing joints.
1. If the seam is closed, i.e. seemingly sealed and the joint reinforced concrete slabs dense, i.e. two slabs fit tightly to each other, there is no way to lay a Vilatherm during inner cavity between the plates. In this case, it is necessary to drill holes every 20-30 cm and fill the joint cavity with mounting foam through these holes. Then it is necessary to seal the seams, i.e. cover the seam with sealant to ensure complete tightness of the seam.
2. If the distance between the boards is large enough, it is necessary to open the seam. Those. need to delete old sealant or tow by cleaning the cavity between the plates. Then lay the cavity with Vilatherm, foam the inaccessible areas and carry out the final sealing of the joints with a sealant.

For an apartment building, this is as much a necessary measure as renovating an apartment. It is mandatory to carry out both in new buildings and in old panel houses that need overhaul. The fact is that if you do not seal the interpanel seams with high-quality moisture-resistant material, then, like not insulating the apartment, there will always be a draft and dampness in it. Large slits between concrete blocks contribute to the accumulation of condensation, which over time will appear on your walls in the form of dark streaks. In order not to have to pay later for expensive repairs, it is better to eliminate the root cause of all this - to patch up the cracks between the plates. To do this, of course, you will have to call specialists in this area, in which any public service should be interested. Many years of experience and professionalism are known to save time and money. You can choose one specific of several types of sealing - it all depends on the state of the building. If the joints in the panel house have not yet been treated with a sealant, then primary sealing is done. After 5-10 years, a secondary is carried out - if the house is in conditions high humidity and damp spots began to appear on the walls and ceilings.

Secondary sealing requires additional work- that is, removal of old materials, selective opening of seams and partial repair of joints. Only after careful preparation is the insulation laid and a new sealant is applied. If the interpanel seams have not undergone a destructive effect and the sealed material later long time is in good condition, it is enough just to strengthen the waterproofing by applying a new layer of sealant. The seams between the panels are opened in the event of their complete or partial destruction, after which all the same work is carried out as with conventional sealing.

Sealing of seams in panel houses of different series.

Sealing of interpanel seams and their insulation in multi-series panel houses is carried out in different ways, since each type series houses has its own construction technology and panel construct. The best technology heat insulation of seams with their subsequent sealing of panel joints is the so-called "Tight seam".

However, there are some features of sealing joints in each specific series of the house. For example, panel slab in series of houses KOPE double, sandwich type. The panel sandwich is empty inside. The air inside the stove could create good thermal insulation if the stove was sealed. However, the slabs are not airtight, and therefore moisture and cold air can easily penetrate into the apartments. Sealing and insulation of houses with similar panels very time consuming. In addition, it requires a lot of materials. Inside the sandwich, polyurethane foam spreads in large volumes. The joint of the panels insulates the Vilatherm. Additionally, the joint is insulated by foaming the cavity of the Vilaterm. Well-made sealing and insulation will make the apartment warm, despite the wrong design and unreasonable construction technology.

In the series of houses of the "old Soviet panel" or p44, or p44t, the slabs are cast, ordinary, and problems appear when there are large joints between the panels, or when the panels are chipped. Cold air cools the apartment as moisture seeps through the space between panels. Mold and condensation constantly form on the cold walls of the apartment. Drafts occur in corners, at ceiling or floor level. Interpanel seams of houses in these series are sealed using the conventional "Tight seam" method. Very often, in such houses, the joint between the slabs is minimal, and therefore it is not possible to lay a vilaterm. In such cases, the seams are thoroughly foamed. Then they are abundantly coated with sealant. Polyurethane foam can last a very long time if the seam is closed with a sealant. Since in this case it has no contact with moisture, air and sunlight. V monolithic brick houses there is a seam between the top floor and brickwork as well as in glazed balconies in the places where the frames of the double-glazed windows adjoin the walls. Builders often hastily foamed these seams and cover them with a galvanized decorative strip. Nice for the commission and cold for the tenant. These seams also need insulation and sealing. And only then they can be closed with a beautiful bar.

If you want your home to be always clean and comfortable, and not "bursting at the seams" from strong wind, you can order sealing of interpanel seams from us. Our construction organization carries out a full range of high-rise work related to the sealing of the seams of an apartment building. All the material we use for sealing is a polyurethane foam based material that prevents moisture penetration and temperature fluctuations. by the most modern technologies will allow the residents of the old house to live for the next 15 years without experiencing any inconvenience.

The cost of repairing joints for private customers

In order to eliminate difficulties with recalculations, our company made a decision and "froze" the prices for the services provided, and as of May 2016 the prices remained the same as they were in 2017.

Repair price and

sealing of interpanel seams

Depends on the type of house and the characteristics of the building, on average, it is

450 rub .

per r. m. with all costs incl. material, work, coordination. We do not provide for any additional costs for the customer and an increase in cost! The minimum amount of work is at least 30 meters.

The number of storeys does not affect the cost of work.

Approximate scope of work for panel buildings:

• - 1st room apartment- the minimum order is 30 running meters,
• - 2-room apartment - 30 linear meters,
• - 2-room apartment located at the end of the house (corner) - from 45 to 79 to linear meters, see the table for calculating linear meters of seams .jpg
• - 3-room usual - 45 running meters,
• - 3 rooms end - from 60 to 95 running meters

Sealing of interpanel seams is carried out along the perimeter of the panel (top, bottom and side seams of the panel). For the last floor, another technical floor is added (since through the voids in the joints of the technical floor, water flows into the interpanel seams of your apartment). For block buildings, the amount of work is about 30% more.

If you know the type of house, then using the calculator, if you select the proposed parameters, you can accurately calculate the amount of work:

Warming of seams and anti-mold treatment

The insulation of the seams is carried out using the "Warm seam" technology - this is when the insulation of the interpanel space is carried out through holes drilled at a distance of 15-20 cm through the "Vilatherm" or thin layer plasters (for some series P-44T, P3-M, KOPE, I-155, etc.)
In series (I-515/5 II-18/12 P II-68 1-515 / 9M, etc.), the insulation can be filled only if the seam is opened. This is called 100% suture opening. Insulation material "Macroflex" is filled into the seam, then the joint "Vilaterm" is laid and the seam is finally sealed with mastic (sealant) "Oxyplast" or "Rustil".
Composition treatment "Anti-mold" carried out if there is mold in the seam.

The technology of works on sealing and insulation in detail:


"Warm seam" is a modern, reliable and durable technology, therefore this way repair (or primary sealing) of joints between slabs is one of the most relevant services of our company. The entire list of works is carried out mainly at height and in any weather, therefore, it requires not only special equipment and unprecedented safety measures, but also remarkable qualifications from the working personnel.
Our company employs industrial climbers with extensive experience, and the main component of the selection criterion for our personnel is (among other things) and high level personal responsibility.

The specialists of our company guarantee a full range of construction works for the implementation of the "Warm seam" technology. This complex of works includes the following stages.
1. Pre-insulating the joints between the slabs to protect them from external precipitation. This stage applies to new buildings and houses that are just being commissioned. The distance between the interpanel space is filled with foam under pressure and insulated with a special tube, which is "recessed" into the foam. Then everything is leveled with a solution and additionally opened with a special sealant. This sequence of actions guarantees the achievement of maximum results in terms of waterproofing, thermal insulation and resistance to UV radiation.
2. The second option concerns the reconstruction of joints in panel houses as part of a major overhaul of the facade. This service is a set of measures to restore sealing and thermal insulation properties seams in accordance with the requirements for new buildings. Moreover, if the insulation is in a satisfactory condition, our masters will carry out the insulation with a sealant from the outside, without violating the integrity of the old insulation.
The specialists of our company offer a full range of repair and restoration work for waterproofing interpanel joints. Such a complex provides for certain technological stages, namely:
 cleaning the seam from the old insulation material (if any), removing the leaky solution or sealant;
 maximum possible degreasing of the seam;
 treatment of the seam with antifungal impregnation;
 flushing the seam against mold;
 arrangement of the seam using the "Warm seam" technology.
Based on the experience of our specialists, we strongly recommend not resorting to the help of masters with a dubious reputation, as well as to those specialists who offer prices below market prices. As a rule, the results of their work appear in the first season. The seam allows moisture to pass through, dampness and fungus appear in the room, and warranty obligations such wizards are not performed (and not always provided).

Seam sealing materials

We use only high quality materials and technologies to restore the tightness of joints with high weather resistance, water and air tightness. What allows you to achieve excellent results, even when performing work with sub-zero temperatures



Mastic color for all types panel buildings, in most cases - white. We use it.


To services of clients - an integrated approach to objects

If you ordered repair or insulation of seams, in the range of services, starting from the coordination of work in the necessary authorities, we also perform:
• sealing of canopies and sealing of windows from outside, in places inaccessible from the premises and during or after installation by window installers.
• repair of balconies and roofs, repair of the loggia and bay windows, window cleaning
• repair and manufacture of roof balconies for the last floors (waterproofing of the balcony roof),
Balconies are sealed along the perimeter, more often these are upper ebb tides. For windows - the excess of polyurethane foam is removed and closed from solar radiation sunscreen mastic.

Sealing external seams

Warranty for work

The main thing is not the chosen technology of work on sealing joints, but the quality of materials and the experience of specialists.

At least half of the total housing stock is apartment buildings built on panel technology... It was she who helped at one time to provide housing for many in need. The main problem of such buildings is the leakage of the joints between structural elements, therefore, in many cases, high-quality sealing of seams in a panel house is vital. necessary operation... Thanks to it, you can significantly reduce energy consumption, improve the microclimate in the apartment, get rid of mold and other related problems.

How the seam is sealed during construction and repair methods

Relatively recently, this process has received limited attention, the pace of construction has always been at the forefront. Most construction organizations used ordinary tow or glass wool to seal the joints, in best case used rubber seals. Then the seam was filled with a standard cement-sand mixture and covered with a layer of bitumen-based mastic, simply smeared.

Due to the fact that any building construction shrinks in the first years after construction, this leads to a violation of the sealing of the seams (even a slight displacement of the panels changes the geometry of the joint). After that, moisture entering the seam completes the destruction of the solution and makes the joint open to all winds and atmospheric precipitation.

Of course, you can close the seam in the same way, but there will be no guarantee of its durability. Depending on the state of the joints between the panels, several types of repair work are used today:

1. If the cement or concrete filling of the joint has not suffered much, most often (especially if the work is performed by housing and communal services workers), so-called cosmetic repairs are performed. This method is the cheapest, but at the same time, the most ineffective type of repair.
2. If the main area of ​​the seam is in good condition, but has some defects (no more than 15%), renovation work are performed according to the principle of partial opening of the seam.
3. The most optimal, though not cheap, is the sealing of interpanel joints using the "warm seam" technology.

It should be said that it is impossible to seal the interpanel seam from inside the apartment, especially high-quality. All work is carried out only from the side of the facade. When repairing an apartment, of course, it will not hurt to fill the opened joints with insulation, fill it with a solution, this will give a certain effect, but it will not radically change the situation.

In addition, it is advisable to seal the seam along its entire height, otherwise there will be no guarantee that moisture that has got into the joint of the panels on the floor above will not destroy the already repaired surface. Therefore, it is best to cooperate with neighbors in this matter, it will be both cheaper (due to the amount of work) and more reliable.

The cost of work is greatly influenced by the need to attract industrial climbers to perform these works on multi-storey buildings, it should be borne in mind that the use of lifting towers and other devices is most often impossible.



Repair without opening the seam (cosmetic)

Most a budget option sealing interpanel seams. In an amicable way, it should be used only when the outer joint coating is in perfect condition. First of all, the seam is inspected, a layer of old mastic (resin) is removed with a spatula. If the cement base is reliable, then in order to save money, you can limit yourself to such a cosmetic finish. But we repeat once more - this method is not correct in most real-life cases.

• The cleaned seam is treated with deep penetration soil, preferably with fungicidal additives, Betonokontakt, Master Fungicidal and others are quite suitable.
• If necessary, the damaged areas of the coating are sealed with mortar.
• After that, the entire surface of the seam is covered with a special water-repellent mastic. On sale you can find various one- and two-component compositions, which one to choose, to decide the work for the customer. Many companies specializing in sealing joints prefer to work on two-component polyurethane-based mixtures, for example, "Oxyplast".

The components of the mixture are mixed with a mixer, while you should follow the instructions on the package. The sealant is applied to the seam with a spatula (its width must be selected based on the size of the interpanel joint, it should be somewhat large). It is desirable to cover the front edges of the panels masking tape, which is removed after applying the mastic (this will make the seam look better).



Repair with partial opening of the seam

If part of the coverage is broken or there is a certainty that behind the layer cement screed there are no seals, then the seal must be done in the following way:

• The damaged cement coating is removed. If only a small part of the seam is opened in this way, it is necessary to drill every 20-25 holes (with a 10-12 mm drill).
• After that, the voids behind the plaster are filled with polyurethane foam. For this purpose, it is better to use a special gun, for which it is more convenient to dispense the amount of foam, which makes it possible to reduce its consumption.
• After the foam hardens, its protruding part is cut off. The entire seam is treated with a primer, and the exposed areas and drilled holes plastered. The final stage the seam will be sealed with mastic.

Warm seam technology

It is possible to seal interpanel seams with the highest quality using this technology. Its cost, of course, is significantly higher (the minimum price for running meter is 300-350 rubles, the total volume of sealing plays an important role). The work is carried out according to the following scheme:

• The interpanel seam is opened along the entire length, the remnants of the old sealant are removed. Damaged panel edges are repaired if necessary. The entire surface is treated with a primer.
• The seam is filled with polyurethane foam, while it should be borne in mind that it has the ability to expand 2-3 times. Therefore, the foam is fed into the depth of the joint and should fill about a quarter of the panel thickness.
• After the foam begins to increase in volume, Vilatherm, a polyethylene foam sealant, is placed in the seam. Vilatherm will not let the foam come out, but will direct it inside the seam to fill all the voids. Such a seal is most often produced in the form of hollow tubes, but solid (non-hollow) modifications can also be found. The size of the vilaterm should exceed the joint width by 10-15%, it is installed in place with a spatula, and is somewhat pressed into the layer of polyurethane foam. Care should be taken during installation to avoid damaging the material. Besides, Special attention it is necessary to pay to the longitudinal joining of the Vilaterm, there should be no gaps.
• Ideally, the vilaterm roll is flush with the outer edge of the panel. To complete the sealing, it remains only to apply a layer of water-repellent mastic according to the technology described above.

This technology for sealing interpanel seams is currently considered the most effective option... Its use allows you to insulate the seam, make it waterproof, which provides not only reliable protection of the apartment from the effects of atmospheric factors, but also increases the operational resource of the building as a whole.



Sealing of interpanel seams in multi-storey buildings should be performed only by professionals with experience in high-rise work. You can experiment on your own only at the level of 1-2 floors, if it is possible to install sustainable forests. Otherwise, it would be prudent to entrust these operations to industrial climbers.
