If the seams of the panel building are not insulated and the waterproofing of interpanel joints is not produced, the walls are very quickly destroyed from moisture and ice (the effect of the dew point), and the tenants suffer from cold, high humidity, mold, leaks and other inconveniences.

It is necessary for all panel buildings. Sealing seams between the panels includes the insulation of the seam cavity and waterproofing the joint of the panels outside. The building panels often have chips and irregularities, therefore inside the interpanel seam not only the technological deformation seam, but also there are large openings formed by defective panels. The space between the panels should be filled with insulation, and the stoves should be waterproof during the construction of the building. BUT B. modern construction Seaming seams are made nominally. The junction between the panels is often lubricated cement mortarand not provided by construction standards, special sealing mastic. Through the unperfect space between the plates, water seeps and cold air penetrates.

Absolutely empty interpanel seam. Square plates on the first floor.

The joints of the panels can be uneven, interpanel space must be insulated, filling all empties tightly. The plates are often offset, so the interpanel seam size can be different. Therefore, high-quality sealing of seams on panel buildings will require the experience and knowledge of technological techniques for all types of slab defects in various series panel houses.

Review of sealing technologies between panels.

Jacket joint stoves - Surface (shallow) Sealing interpanel seams. This method (technology of work) repair of seams does not imply autopsy and remove the old sealant. Waterproofing mastic Apply right on it from above. This method of repair is applicable in the event that the former layer of mastic is damaged, and the heat-insulating material saved its properties completely. It is usually used to give the visibility of work produced.

Waterproofing joints plates- Sealing seams with pre-removal of old sealing mastic. A complete stripping of the joints of the slabs from the previous sealant is carried out. A fresh layer of mastic is applied to the clean interpanel jack. With this technology, there is no insulation of the seam. If the vertical seam of the building is completely littered, it will help from leaks outside the house on this site. But the cold will still penetrate the horizontal seams.

"Warm seam"- more efficient seams of seams than previous ones. Full or partial cleaning of interphaline space and the joint of the slabs from the old sealant and the seal is performed. Then the insulation of Wilaterm, whose cavity is sometimes gateing. Sometimes they join the seam cavity on the surface, but most often cost without expensive mounting foam. And then shut off the butt plates with sealing mastic.
Sometimes with this technology of work, the cross-plates of the plates are placed on the entire depth, calling the technology "warm seam +" in this case. From the point of view of insulation it helps, but still is a semi-dimensional. It is necessary to warm up all seams, all depth. Therefore, the best seams of seams are "dense seam".

Sealing seams on the technology "dense seam". Sealing seams.

The most advanced method of insulation and sealing seams is "dense seam". Unlike other technologies, the technology of "dense seam" does not combine the use of a twilterma or foam, and the complex and systemically used and the ventilation foam.

As a matter of fact, the technology "web seam" is the same as "warm seam" plus a capital foss of the seam cavities for sealing the entire interpanel seam space. With the "warm seam" in best case The cavity inside the Vilaterma and the foam expanding the "swollen sausage" the interpanel space is well compacted, but it works with a perfectly smooth stove butt. On practice reinforced concrete plates inside the cholesis and interpanel space incorrect geometric shape With unpredictable in size of openings. When the house is building, builders are trying to mount the slabs in chips inside, so that the house makes a good impression. As well as during the sediment of the building of the vertical and horizontal seam shift, forming interpanel space incorrect formSo Vilaterm with the "warm seam" insufficiently insufficiently insulating seams. For quality insulation Interpanel seam, it is necessary to marry not only the cavity inside the Vilaterma, but also the space behind the Vilaterma, without regretting the mounting foam. Then the joint of the panels must be highly selected with good mastic.

Even following simple everyday logic, compare the stove thickness and the diameter of the insulation. Thickness panel plate From 30cm to 70cm, depending on the series of houses, and the insulation vetelm has a diameter of up to 70mm, usually 30mm or 40mm is used when insulating interpanel seams. Thus, with the "warm seam", only the outer part of the stove is insulated. If your neighbors did not produce insulation and sealing of seams, then the cold air will penetrate to you through the "neighbor's seams". The output is one - to produce insulation with the help of Vetelma - outside the seam, and the mounting foam is in depth, between the panels. You need to gate all the empty space between the slabs using the "dense seam" technology. The use of the mounting foam "flies to a penny", so management companies at best use the technology "warm seam +", i.e. We pointed crossmen, and then "in a little bit." Real insulation implies full filling of the seam by polyurethane mounting foam. Mounting foam allows you to achieve proper seal seals. Polyuretan as a heater is widely used in construction, for example, in clinker panels, sandwich panels, applying a foamed insulation of the roof and walls.

If a sealing seams The joints of the panels were not produced or carried out not qualitatively, water can leak into the apartment, staining along vertical seams and spreading horizontal. Or to form in the form of condensate on a cold wall. Cold air penetrates through the cavities of the seams and blows the heat from the apartment. On the walls in the apartments, fungus and mold are formed, the plaster drops wallpaper and falls. In winter, such apartments can be easily sick with flu.

Each residents of modern panel house sooner or later it comes to the conclusion about the need for quality sealing interpanel seams.

Sealing materials must have elasticity. Since the seams in the panel house are concentrated on themselves all the load. When draining at home, rigid non-elastic seams are inevitably crackled. For example, the cement mortar used by the builders cracks, various profiles and cords from hydrophilic rubber are unevenly deformed. The most correct is insulation and sealing of seams with a dense filling of voids between the seams of elastic materials using the "dense seam" technology.

This is a waterproofing of the wall of the wall plates of the building and filling the space between the panels. Warming of seams It is achieved by the full filling of the space between the panels. First, between the panels is laid by Vilaterm. After that, in the hole done in the Vilaterme, all intamary space fill foam. Vilaterm prevents the outlet of the mounting foam outside. Foam fills all empties inside the seam, forming a deaf plug. Then the junction between the panels is riveted with sealing mastic.
Sometimes the panels are very small, i.e. The panels are tightly pressed outside, and there is still a cavity, deformation seam. In this case, the Vilater does not go. The seam is filled with foam through the bored holes, and the joke is sealed with mastic. The foam in this case is completely closed with panels and serves for a very long time, and the sealant prevents moisture penetration inside the seam.

High-quality sealing of interpanel seams and insulation of the interpanel cavity can only be carried out on the necessary technologies and necessary materials. Any deviation from technology or in choosing materials, when sealing seams, leads to deplorable results.

Qualitative repair, insulation and seaming seams implies Conducting work on the technology "dense seam" With subsequent waterproofing of the junction between the panels of sealing mastic.

Sealing and insulation of seams on technology "Tight seam" Fully insulation and seals complies. Many firms only partially solve the problems of insulation and the tightness of interpanel seams, as they violate the technological order of work. Either the cavity of the Villater is simply marked, or they are paved with empty Vilaterm, but do not bounce cavity between the panels. Or do not pull the old, rotten the seal. We guarantee high-quality - dense insulation of seams, providing a complete seal of interpanel space and waterproofing of an external joint wall panels.

If the sealing of the seams is performed for the first time, it is necessary to dismantle the cement mapping (plaster) made by builders, then remove the pass or rubber (boards, rags), which builders filled the space between the panels. And then it is necessary to produce high-quality sealing of the seam (junction waterproofing). If seam sealing has already been carried out, but the necessary result is not achieved, it means that technology was broken or not used qualitative materials. In this case, it is necessary to repair interpanel seams. It is necessary to examine on the spot which repair seams produce. If the Vilaterm in the seam is already laid, it is necessary to simulate seams and sew the joint. If the seam is completely insulated, the sealant was just cracked, then it is enough to wash the seals between the panels.

Primary and secondary sealing of seams of panel houses.

Primary sealing of sews Called sealing of non-selected seams. Currently, most houses are handed over to developers with sealed seams. Secondary sealing - This is a cosmetic or major overhaul of sealing interpanel seams, depending on the degree of destruction.

Cosmetic repair and sealing of seams in panel houses.

Cosmetic repair and sealing of seams Includes stripping the seam edge from the old sealant and applying the plates of the new sealing mastic on the joints. Cosmetic sealing of seams is made if old layer Sealing mastic crackled or partially fell off. But at the same time, the insulation inside the seam was preserved, as well as there are no flow or freezing of walls indoors, or other signs of seam defects.

Overhaul and sealing of seams in panel houses.

Materials used to seal seams.

Sealant (Sealing mastic) - the main material for waterproofing and insulation of interpanel seams and joints. From the sealant depends on how reliably, the seam or joint is waterproof. If the sealant qualitatively "passed" to the seam, the moisture will not fall inside the seam and ice will not form. The service life of the entire building depends on the sealant!

Sealing mastic - This is a composite material based on polymers, mainly polysulfide or liquid silicone rubbers. Sealants are used to fill various slots and cracks in order to ensure their impermeability, it is used to seal interpanel seams, as well as to fill emptiness around window and door boxes, heating pipes, water pipes, on junctions and bends.

Vilaterm - It is an environmentally friendly sealing material, made of foamed polyethylene. In the form of Vilaterm is a hollow cylinder. Vilaterm is used to fill emptiness between the plates.

Mounting foam - This is a polyurethane foam seal. Used to fill emptiness. After leaving the cylinder, the foam is polymerized and expanded, filling emptiness. After some time, up to 24 hours, the mounting foam continues to expand and seal the seam. High-quality mounting foam should have adhesion (compatibility) to materials, the voids between which must be fill.

Sealing seams in apartments.

The apartments above 2 floors produced by industrial mountaineering. This requires access to roof.
To gain access to the roof of the building, it is necessary to apply to the designer in the name of the chief engineer on behalf of the tenacious apartment in which the seams or sealing of the balcony joints will be sealing.
This statement is attached by a guarantee letter from our company, our guarantees do not damage the roof of the building during work. As well as IDP certificates that will produce interpanel seams.
We ourselves will take these documents in Dez. From the customer only the signature is required on the statement.

Required conditions for the qualitative sealing of interpanel seams:

1. Dry weather. (temperature maybe any)

2. Quality I. necessary materials Depending on the type of facade of the building.

3. Roof access. (Issue for 1-2 business days) Leave the request to or call back.

Sealing of the seams of glazing and the panels of the ventilated facade.

Sealing of seams and joints of metal structures.

Metal prefabricated structures, various hangars, warehouses, require seams. The main reason for the roof of the roof of such metal structures is that the joints between roofing sheets Poor attracted to the crate. And the gap between the sheets is quite large. The large slot will flow in any case, despite the amount of sealant used when seaming seam. The only correct roof repair method will eliminate large slots between sheets designAnd then sealing the joints of the metal structures.

Sealing plaster seams.

In some panel housesIn order not to produce planned sealing, developers produce interpanel seams plastering mix. In this case, the interpanel space is not filled. Just shook the joint panels. Inside, emptiness remains between the panels. Moisture and cold air still seep through the plaster, and from the roof water can spread over the empty seams into the apartment.

Open the plaster interpanel seam across the entire length is sometimes difficult. For example, the interpanel slot is very narrow and plastered "conscience" concrete of increased strength. In this case, you can produce high-quality filling of interpanel space using a mounting foam. It is necessary in the seam to sew holes after 20-30 cm and through the holes to fit the seam. Foam expands inside the seam and fills empty space. Then it is necessary to wash the seam sealing mastic on top of the plaster to fully hydroize the seam. In this case, the plaster seam over the foam serves excellent protection for the insulation (mounting foam) from the coloring, and the sealant layer over the plaster is the excellent protection of the entire interpanel seam from moisture.

Drilling plaster seam. Application sealant.

What is also useful to know about the insulation of seams and the waterproofing of the joints.

IN winter Water freezes in interpanel seams and facade cracks, and this leads to the expansion of the slots and seams, and the destruction of the wall. It is no secret that the ice has a power capable of destroying metal structures, concrete, stone and other materials. Water penetrates the wall of the facade through, and turning into ice expands the material, which leads to the destruction of the building. Do not tighten the panels with the repair of the panels and you will extend the service life of your building.

If the distance between the panels is too large, the seam is insulated by laying a tubular insulation to Vilaterm. The main insulation in interpanel seams is the mounting foam. The mounting foam fills all empties between the panels: narrow slots, which will not climb the Vilater and the depth of the seam between the panels. And then, at the final stage, the sealing mastic is applied between the panels.

There are signs for which you can determine whether the repair of seams of panels is needed by your building. The main of them are flowing, freezing, the dampness of the walls, drafts in the corners. You can apply seams on the seam at a negative temperature, but not in crude weather.

Sealing of seams of panel houses:

Professional sealing of interpanel seams and insulation of interpanel space is necessary workIn order to forever get rid of their accommodation from the flow, freezing and mold.

The overhaul of interpanel seams is carried out only on the technology of "dense seam", developed by the engineers of the Stroyalp group of companies. According to which the SNIP on the sealing of the seals of large-pointed buildings was adopted.

Warming and sealing of joints of windows and swells:

In order to get rid of the mold around the windows, the windows are sealing - sealing of joints and jamming of double-glazed windows and panels, insulation of tumps and panels.

Sealing interpanel seams in panel houses of different series are produced by different technologies, as the designs of houses and panels are different.

Warming and sealing of flasks of apartments includes sealing of interpanel seams, sealing of loggias and balconies, sealing of windows and sings, as well as if necessary, insulation of seams from the inside - from the side of the apartment.

Materials for seaming seams should be selected based on the used seams of seams and a series of houses. Sometimes in one series of home developers use different facing materialsTherefore, it is often necessary to separate selection of sealant for better adhesion to the surface.

Sealing interpanel seams, insulation and sealed windows and loggias are the main activity of the "Stroyalp" Group of Companies for 20 years. Our sealing technology of external seams "dense seam" gave start to develop a new SNIPA on the sealing of external seams of large-pointed buildings. The proposed technologies of previous generations will not be able to fully insulate and sew the seams in the panel house.

Sealing of the seams of the panel house includes the following types of work:
- Sealing interpanel seams: insulation of interpanel seam and applying sealant on the joint panels.
- Sealing of the loggia: insulation and sealing of bogs of loggias and panels (outer walls).
- Sealing window seams: insulation and sealing of windows in places of joints of panels and double-glazed windows (windows of windows and outdoor wall panels).
- Sealing of the loggia: repair soft roof Loggia (usually on the top floor) and sealing of the seams of the loggia.
- sealing seams monolithic belts: Repair, plaster and tightness of belt in monolithic brick houses.

Sealing interpanel seams apartments for individuals with materials - price per meter "by key":

1) Secondary sealing Price (stack of joints) - from 325 - 370 rubles / mp. with materials (restore sealant without insulation).

2) Primary sealing Price with insulation (for example in new buildings) - 550 rubles / mp. with materials.

3) Repair of interpanel seams and sealing joints (repair closed seam: Filling the interpanel space by mounting foam through the technological holes and sealing mastic) - 550 rubles per mp. with materials.

Watch on the topic: Various technologies Sealing interpanel seams.

Technologies of primary and secondary sealing. Old technology "Warm seam". The overhaul of interpanel seams is carried out only on the technology of "dense seam", developed by the engineers of the Stroyalp group of companies. According to which the SNIP on the sealing of the seals of large-pointed buildings was adopted.

Sealing and insulation of apartment seams with their own hands.

Repair of panel seams do it yourself, if you are not a climber, it is possible only on the first floor. At the same time, for a qualitative result, you need to accurately comply with technology and apply high-quality materials. It is also possible to insulate interpanel seams in the apartment with inner. It is necessary to drill in the corners of the outer walls of the hole and gently reap. In any case, it will be warmer, but completely interpanel space you inside not to get. And joke vertical Wall With the ceiling and floor, the so-called castes of the seams - also do not get it, it needs to be done outside.

Sealant and insulation for sealing interphaline seams.

Sealants for interpanel seams.

There are many varieties of sealants for large-pasted buildings: polyurethane, acrylic, butyl rubber, thiocole sealants. Each sealant has advantages over any particular properties. Sealant for interpanel seams should have good deformability and adhesion. Good adhesion allows sealant to get absorbed into the concrete surface of the plate at any temperature. Good deformability allows sealant to stretch in seasonal temperature expansions and compression plate and not crack.

Insulation for interpanel seams.

There are two main types of insulation for interpanel seams:
- Vilaterm - tubular insulation, which is paved close from the surface of the plate at a distance of no more than 50mm.
- Mounting foam - polyurethane foam in spray balls, which can fill the entire cavity of the interpanel space.

See more: Materials for sealing interpanel seams.

High-quality sealing and insulation of interpanel seams depends largely on the materials used. It is no secret that many managers are used to seal large-pasted masses, which are not intended to seal concrete surfaces.

Sealing of joints of windows and panels.

The common problem of windows in panel houses is that the tightness of the adjoints between windows windows and the building panels is missing.

When building a house, the joints between the window frames and panels are attached, or the panel comes to a building with windows. In any case, the joints are plastered, shaded and painted. Water and cold appear in clear form does not penetrate, but the frames are almost always cold, since the cement solution is not insulation, and over time she passes and moisture.

If a replacement of old window Rams on the plastic glass windows, window companies close the joint between the frame and the mounting foam panel without protective sealing of the joint. Mounting foam is insulation and at first in the apartment heat. But the mounting foam is afraid of exposure external environment, solar ultraviolet and moisture. Within a short time, it swings and crumbs, so the slots appear in the joints in which the wind and moisture penetrates. In order to eliminate all these problems, it is necessary to close the foam in the layer of sealing mastic.

Over the sealant can be put galvanized, painted platbands. Over window slope Mount a wide sweat, for the leads to water, and not a narrow castler over the frame, how the window companies are put, which, on the contrary, contributes to the waterfront of the water into the upper jack between the frame and the panel.

In order to get rid of the mold around the windows, the windows are sealing - sealing of joints and jamming of double-glazed windows and panels, insulation of tumps and panels.

Sealing loggias and balconies.

Loggias and balconies are often blurred in all panel houses.
The main problems of loggias and balconies of panel houses:
- loose and leather adjoining and jacks of double-glazed windows in glazed loggias.
- loose and leakage adjoins and joints around the loggia or balcony.
- There are no sifts or incorrectly installed.
- Worn soft roofing of a loggia.

The leaks and jacks and walls and walls in glazed logs are also sealed as in the junction of window frames with panels. The sealing of a loggia or balcony is made according to standard seams of seams between panels. And the replacement of the soft roof of the loggia is made according to the standard technology of the soft roof device from waterproofing materials.

Errors and violations of the technology of sealing and insulation of interpanel seams.

Consider the reasons for the unsatisfactory result of sealing in panel houses.

Although many companies have accumulated a lot of experience, errors associated with the sealing of joints, allow us to talk about the need to develop new construction standards To solve this serious problem.

Sealing seams on the first and last floors.

Residents of the first I. last floorsAs a rule, more others suffer from problems with interpanel seams. During precipitation on the roof or the technical floor, water accumulates. If the seams between the panels have cavities, the moisture is seeping through them, which over time is manifested in the form of mold in residential rooms. The first floors are more likely to suffer due to empty seams.

We will be happy to fulfill any work for you!

Sealing seams in panel houses with cosmetic repair It is unlikely to solve all the problems. Currently this is the most inexpensive way, but it is necessary to use it only when there is no serious damage.

First, inspection and make an assessment of the states of the seams, and only then make a plan of action and choose a solution. If during the construction, the installation and sealing of the docking seams in the panel building was performed well and now there are minor damage, then you can resort to cosmetic repairs.

Sequence of work:

• Damaged joints between panels are thoroughly cleaned from old material and dirt.
• Then the surface is treated with soil impregnation deep penetration. This work is important to fulfill with great responsibility, since the quality of the seal depends on it.
• The internal space of the seam is filled with thermal insulating material and covered with plaster composition.
• After that, mastic for sealing, protecting the repaired portion from the destructive impact of moisture, is applied to the surface. It is recommended not to save on this material, as using cheap mastic, not avoid repairs in the near future.

Since cosmetic repairs are considered quite primitive, it is necessary to emphasize on the quality of the materials used. This at least somehow guarantees a good durability of sealing joints of external walls.

Local repairs

The procedure for the device of interpanel seams during local repair is as follows:

1. As with any form of repair, work on sealing is starting with inspection of damage. Foci detects with strong surface defects and start repair.
2. Sowing and cracking cement are removed by the construction spatula.
3. Then, at a distance of about 2 cm, the holes are drilled from the perforator, which are filled with the mounting foam. The better than the empties will be filled, the more hermetically seam.
4. The extra parts of the mounting foam are cut off with a construction knife, after which the surface is ground and coated with a layer of plastering composition.
5. Ending seams in panel houses with mastic applied.

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

Similarly, the pipe sealing on the roof or sealing the seams between the slabs of the overlap is performed.

"Warm seam"

This sealing technology of interpanel seams is considered to be the most efficient. The cost of works depends on the length of damaged areas and is usually greatly exceeding the costs of cosmetic repairs.

Sequence of actions on the technology "Warm seam":

• The junctions between the panels are completely revealed. Unlike local repair, here work is done along the entire length.
• Old thermal insulation material is completely removed.
• Damaged panel sections need to be repaired, seal cracks and chips.
• The inner surface is treated with soil impregnation. It deeply penetrates into the pores and prepares the seam for sealing.
• Seams are filled with a small amount of construction foam, as it possesses good thermal insulation properties And, expanding, does not leave emptiness. Performing this work, you need to be careful that the foam does not hit the skin or in the eye.
• Without waiting when foam will increase in volume, start laying heat insulating material (Polyethylene foamed). In this way, construction foam It will remain inside the seam, filling all the gaps and emptiness.
• After that, they begin to apply mastic for finishing seams. It is important not to leave uncovered seaflings, as in this case the moisture will be able to get inside the seam and destroy it.

Similarly, sealing windows from the street side, as well as the sealing of the roof. Technology "Warm seam" is capable of providing house for many years reliable protection From moisture penetrating into the joints between the panels.

Despite the higher sealing price for this technique, you will save a lot of money, as you need the nearest repairs no earlier than in 10-15 years.

One of the problems of panel buildings are poorly sealed interpanel seams. This may be expressed in the wetting of walls, the appearance of fungus, impaired sound insulation. Poorly sealed joints make not only discomfort in the apartment, but also the cause of the destruction of the panels, and the welded interpanel compound may lose its strength. Most of all the harm is inflating and moisture in the seam. To solve this problem, it is necessary to carry out insulation of interpanel seams and their repair. These works require large labor costs and are carried out by contracting organizations, as a rule, they are timed to another repair of the house.

Primary sealing and insulation of seams in panel houses is carried out at the stage of their construction. After the installation of the floor panels in the pure groove is stacked by the insulation, the joint is filled with a solution, and the outside is sealed. On this work end and the seams are considered compacted. In the future, during the operation of the building due to the shrinkage of the house and the panel shift, the sealing of panel seams is disturbed. After that, the tenants begin the problems.

Works on the sealing joints of panel high-rise buildings are performed with the involvement of industrial climbers. The main purpose of seaming seams in the panel house is to prevent moisture from entering the inner cavity of the seam and preventing the freezing of the compacted seam in the winter. Materials for sealing interpanel seams are used:

• sealing mastic or sealants;
• waterproofing harness;
• vilaterm;
• mounting foam.

The use of listed materials depends on the type of repair. With cosmetic repair, seams are cleaned with damaged mastic. If the freezing and leaks of moisture were not, and the insulation is not damaged, then only a sealant or sealing mastic applies. Not all companies and organizations in the market of these services in good faith and efficiently perform work. Some of them are sandy-cement solutions for sealing seams. Many firms stopped applying bituminous mastic as a sealing material. First, she spoils appearance Buildings, and secondly, paint, applied to mastic, flakes and disappears.

Firstly, it spoils the appearance of the building, and secondly, the paint applied to mastic is peeling and disappears.

In case of major repairs, the joints are revealed completely and the insulation replacement is carried out. It is then taken sealing and painting. If the maintenance technology was observed, such compounds will serve not one year. In a large account, from how to close the seams in the panel house, the service life of the building itself depends. A combination of cosmetic I. overhaul - This is the secondary sealing of interpanel seams in the panel houses.

Methods and joint repair technology

The main requirement for high-quality repair is the use of properly selected benign materials and step-by-step implementation of the work of work. Usually release 3 methods of repair:

• wiggage of seams;
• waterproofing work;
• "Warm seam".

The junction of the junction is performed without its autopsy and replace the sealant. Mastic is applied on it from above. This method of repair is applied in the absence inside the apartment of the visible signs of the sealance of the seam, and the damage to the external layer of sealant is insignificant. These works are usually carried out during cosmetic repair.

Waterproofing of the joints occurs with their full cleaning and replacement of the sealant. The insulation of the joints is not done. Usually use one-component polyurethane sealant For interpanel seams and joints Hermafelex 127. This material is ideal for insulation of vertical seams, has a wide range of temperatures (-50 ° C ... + 80 ° C) operation, quickly solidifies. White or graycompatible with all types facade colors. The warranty service life is 8 years. The sealing of interpanel seams on such technology will help protect them from moisture from entering, but the cold will penetrate the room through uncomfortable horizontal joints. Sealing outdoor seams are works to prevent water from entering them. For this purpose, waterproofing compositions are used and the seam is filled between the panels of the mounting foam, which creates an insulation effect.

Thus, foam is completely between the plates and is protected from ultraviolet rays. This extends its service life. The sealant protects the joints of the plates and prevents the water from entering them. As a result, the embedded joint eliminates the appearance of fungus and mold in the room.

Warm seam

Technology Warm seam is new and more efficient than above. In accordance with it, completely or partially interpanel seam is opened. Remove old sealant and insulating material. The joints are cleaned of garbage. After performing these works, the hollow insulation of Vilaterm is stacked. His cavity, if possible, fill the mounting foam for better seam seal. The joke must be lured by a sealant or sealing mastic. However, with such technology, the entire bay cavity is not filled. To solve its full filling it and, taking into account the shortcomings of other methods of sealing, insulation technology called a dense seam was developed.

At and the technology is an improved version of the warm seam. It provides for sealing seams in the panel houses full filling of the mounting foam as the insulation of Vilaterm and the space behind it. The horizontal groove of the panel house is filled in the same way. After that, the joints are sealed using mastic or sealant. Thus, if they did not seal them in neighboring apartments, then the cold air through the laptile joints to get to you could not. Work should be carried out in dry weather, while the air temperature should not be below -15 ° C, upper limit Temperatures are not regulated.

Heat the grooves can be without its opening. This situation occurs if it is too narrow or has been embossed outside with a strong solution. In this case, the height of the joint is drilled in a pitch of 20-30 cm. Through the mounting foam holes, their seal is carried out. Work is held from the bottom up.

The junction is considered compacted if the foam went through holes. Surplus foam are cleaned. The thermal insulation in this case does not fit, and its role performs foam. Mastic is applied over cement coating. To prevent the walls in the apartment, the junction should be chosen in this way.

The high-quality sealing of interphaloneal compounds is possible only with full compliance with the performance of the work and the use of the materials specified in it. Otherwise, the work carried out does not reach the desired result. Works above the 2nd floor are performed with the involvement of industrial climbers.

Insulation joints from the apartment

It is possible to seal them from the room. Such works are usually carried out during the repair of the apartment in the absence of furniture in the room. Before close the joints, it is necessary to determine the scope of work. For this, they are opened and check the presence of a sealing material in it. If it is installed by builders and in good condition, then construction foam is used for insulation. To bounce the space between the paz panels, you can completely not open, but to make drills along it. Works are carried out on the floor to the ceiling. The upper and lower joint is used to be insulated throughout the entire length, and not only in places connecting plates.

In the absence of insulation inside the compound, they are completely opened and purified from dirt and dust. Before laying, the Vilater is paving the construction tape or the mounting (building) fliesline, a small layer of foam is applied to it. After that, so far the foam is not frozen, the insulation is stacked and pressed with a wooden spatula. This operation must be taken carefully not to damage the material. Then the remaining cavity fill foam with such a calculation so that when soaring it does not come out. The joke is closed with cement mortar, and then sweeping. Sealing mastic in this case do not apply.

Residents of the 1st floor of panel houses have the ability to repair interpanel connections outside the building on existing technologies. Such a repair is no different from the work performed from the inside of the room, except that the joint will be soaked with a solution, but mastic for sealing interpanel seams. Since the sealing of the seams will be carried out from the stairs or the gratings, then it is necessary to comply with the requirements of safety techniques when working at height.

Over time, residents understand that the quality warming and sealing of the seams in the panel houses will be pledged comfortable accommodation In the apartment without fungus and mold.

At the end, you can watch a video on how Spider MAN warms interpanel seams in high rise:

High-rise work on sealing and repair of interpanel seams is in demand for most types of panel buildings. Residents of the first and second floors of "Khrushchev" or high-altitude houses built on Czech technologies can conduct such works on their own. For higher floors, qualified sealing of interpanel seams by experienced industrial climbers will be required.

Interpanel seams are called technological emptiness between factory reinforced concrete panelsleft when building a building to compensate for shrinkage at home, possible soil shifts, temperature differences. IN standard technologies Soviet construction To fill the seam in a panel house from the facade side, a conventional panel was used, covered with cement mortar.

The same technology was used to fill the seams between brick masonry and inter overlap In houses of frame structures.

The shortcomings of such a seam manifested itself after 5-6 years of operation.

Especially dangerous for cement tie. Excessive moisture in microcracks, which, when freezing, ruptured seams.

In all buildings of the outdated design, the destroyed intercutric seams become the main source of water leaks, cold air.

Explicit signs of the destruction of the sealing of interpanel seam are the influx of cold air when cooling, appearance in the apartment of mold in ceiling floors or in the corners of the rooms.

Additional sealing and insulation requires a later rubber waterproofing of seams closed with metal lining from the facade side. Silvering and complete destruction of low-quality rubber manifests itself after 10-12 years of operation of the house. The low quality of high-speed construction was reflected in the installation of wet factory wall panels. When installing in the fall or winter, the wet concrete cracks under the influence of a low temperature, such walls easily differ on the grid of small cracks.

Cost of sealing of seams in Moscow and Moscow region

When ordering high-rise works, the prices for sealing interpanel seams in Moscow and the Moscow region depend on the complexity of the technology, the height of the building, the number of operations. Rates of standard operations (primary seal sealing, partial filling of cracks, stoves) are measured in straight meters. It is also regarded by work on the secondary sealing of interpanel seams, requiring opening of the joint, the removal of the old sealant.

Individual contractual rates are applied when repairing walls with a large area of \u200b\u200bcracks in concrete, requiring continuous surface treatment (except sealing of seams), with complex orders, including wall insulation, cool-gauge repair metal roofs. The overall estimate of work "turnkey" includes the cost of materials that the customer chooses independently, according to the recommendations of the contractor.

Types of jobs	Units	Price, rub
Primary insulation and sealing interpanel seams	rm. m.	from 150.
Grinding interpanel seams and junctions with removal of old sealant (secondary sealing with opening)	rm. m.	from 250.
Repair of interpanel seams followed by sealing	rm. m.	from 300.
Sealing cracks on the walls	rm. m.	contractual
Sealing metal roof	rm. m.	contractual
Sealing the roof of the balcony	rm. m.	from 5000.
Sealing of visors and sweating	rm. m.	from 350.
Sealing double-glazed windows (windows)	rm. m.	from 450.

Shavov processing technologies

IN modern technologies Sealing seams by cement-sandy solution gave way to easier and durable materials.

Cement-sand screed, even fortified liquid glass, It is destroyed much faster than synthetic sealants. When sealing seams, the gloves use tubular or foamed insulation, providing additional waterproofing and thermal insulation. Sealing by construction installation foam belongs to inexpensive technologies of "warm" seam. For the Moscow Winter Climate, the Norwegian or Swedish foam, developed for the Scandinavian colds, is excellent.

The secondary sealing of interpanel seams in panel houses provides a number of technological operations:

• extection or stroke of seams;
• removing an old insulation or sand-cement mortar;
• processing of internal concrete surfaces by bactericidal solutions;
• sealing emptiness insulation, mounting foam, elastic materials;
• the final coating of the treated surface with mastic.

The multilayer sealing of seams uses a number of modern materials. Among high-quality sealants and insulation, silicone, acrylic, thiocole materials, foamed polyurethane can be distinguished. Modern materials elastic, durable, moisture resistant, well adhesion with concrete surfaces (penetrate into the outer layers of concrete).

Among the inexpensive domestic materials, a thioco sealant "Sailast", polyurethane "Akatamast", acrylic "oxyplust", "Aksa" can be distinguished.

Everywhere the gloves apply a tubular "Vilaterm".

With high-altitude works, industrial climbers descend down the wall of the building on firmly fixed ropes, processing joints on a surface of about two meters width.

In addition to the usual building tools, special equipment from the arsenal of climbers is used for work: special devices for descent and securing on-site, duralumin platforms, ladder, zhumara, safety carbines.

With high-altitude seams of seams, enhanced security measures are required:

• reliable fastening of safety ropes on the roof;
• insurance of workshooting, tools and equipment;
• the fencing of the territory at the place of high-rise works;
• limit the dimensions of the RVS in height only with a load capacity of the cranes;
• wear warning plates for passersby.

The competent work on sealing of seams is safe for residents and equipment to be repaired building.

Additional sealing features

High-rise sealing of seams in panel houses from the outside can be ordered as separate operation Or becomes part of a comprehensive order. Improve the tightness of the compounds between the plates is necessary before insulation of the outer surfaces of the building walls, with the complete reconstruction of the facade (in front of plastering, finishing operations).

TO additional work Treatment of joints with sealants with bactericidal preparations (to combat mold), repair of the metal roof of the building, the insulation of the gaps between the walls and window passing, Installation of visors over the balconies. Especially efficiently for insulation, multilayer filling of joints of windows with wall openings consisting of sealant, insulation, mounting foam, decorative finish.
