Repair of seams in panel houses: the technology of work and who should do them

Panel houses offer benefits, but they also present a unique set of difficulties. Needing to repair seams is one problem that panel house occupants frequently encounter. The building’s panel seams may experience degradation over time as a result of aging materials, weathering, and structural movement.

In addition to preserving the building’s aesthetics, repairing these seams is essential to guaranteeing its structural soundness and energy efficiency. We will examine the materials and techniques utilized in panel house seam repair technology in this article.

Prefabricated panels consisting of brick, concrete, or wood are used to build panel houses. Although these panels are quick and inexpensive to build, they may eventually exhibit problems like shifting and cracking. Consequently, there may be possible leaks, drafts, and other issues as a result of damage to the seams connecting these panels.

Understanding the nuances of the process is crucial when it comes to panel house seam repairs. Many aspects need to be taken into account, from determining the extent of the damage to choosing the right tools and methods. Furthermore, ensuring the work is done correctly and safely depends on knowing who should do these repairs.

Seam repair in panel houses: who should do it and how technologically? Poorly sealed panel to panel joints are just one of the many issues panel houses have. This could show up as damp walls, fungus growing on them, or a breach in the soundproofing.

Inadequate joint sealing will not only make living in the apartment uncomfortable, but it can also lead to panel destruction and weaken the welded joint. However, freezing and moisture in the seams cause the most damage.

Panel house joint repairs and insulation should be done in order to address this issue.

Contractor groups complete this costly work when the house is being repaired in the future.

Types of repair

Primary joint sealing and insulation are completed during the panel house construction stage. After installation is complete, insulation is inserted into neat grooves, the joint is filled with mortar, and the joint is sealed from the exterior.

The work is regarded as finished at this point, and the joints are sealed. The panel joints’ sealing is compromised during the building’s subsequent operation as a result of panel shifting and house shrinkage.

This is when the tenants start to have serious issues.

Industrial climbers repair the inter-panel joints in panel houses. Caulking is primarily used to keep moisture out of the joint cavity and to keep the sealing materials from freezing in the winter.

These substances are applied as sealants:

• Sealants or sealing mastics.
• Vilaterm.
• Tourniquet (waterproofing).
• Mounting foam.

Depending on the kind of repair being done, all of the aforementioned materials may be used. The sections of the seams where the mastic has been damaged will be cleaned if your home is receiving cosmetic repairs. Use one sealant or mastic with sealing properties if there were no moisture leaks, freezing, or damage to the insulation.

However, take note that not all businesses and organizations offering these services carry out their work in an ethical and high-quality manner. Some of them seal seams with mortar made of sand and cement.

The majority of businesses no longer use bituminous mastic as a sealing agent.

This is because it detracts from the building’s appearance and, if paint is applied, causes the paint to eventually peel and flake off.

When doing a major repair, all of the joints must be opened, and the insulation must be completely replaced. Painting and sealing are then completed.

Such joints will last longer than a year if the repair work was done using technology that was observed. Yes, the way the joints are caulked will determine how long the building lasts in terms of service.

We will get secondary sealing and inter-panel joint repair in panel houses with a mix of major and cosmetic repairs.

Technology and methods of repairing joints

Precisely chosen, premium materials and precise fulfillment of all production technology are the primary requirements for high-quality repair work.

There are 3 main ways of repair

• Seam sealing.
• "warm joint".
• Waterproofing works.

When it comes to caulking joints, this type of work is done without opening and changing the primary sealant. Mastic is used from above in this instance.

When there are no obvious indications of leaks within the apartment and the joint’s surface damage is minimal, this repair technique is employed. Typically, these tasks are completed right away when performing cosmetic repairs.

Joint waterproofing involves replacing the sealing material and thoroughly cleaning the joints. However, this joint insulation is not done at all.

Use Hermaflex 127, a polyurethane one-component sealant, for joints and inter-panel joints as a general rule.

This material hardens quickly, can tolerate temperature changes over a reasonable range (-50 to +80), and performs exceptionally well as a vertical seam insulator.

It blends flawlessly with any kind of facade paint and is available in white or gray hues. There is an eight-year warranty period. By using this technology to repair the inter-panel joints in panel houses, moisture can be kept out, but the cold will still be able to enter the room through the horizontally undone joints.

We’re not talking about cold here; sealing the outer joint suggests that it will only act as a barrier against moisture and water seeping inside. Waterproofing compounds are used for this purpose, and foam is used to completely fill the joint between the panels, producing an insulating effect.

Keep in mind that the foam will be shielded from UV radiation because it will be positioned between the slab in this manner. This will increase the life of the service. If a sealant was applied, it will keep water out of the joints and boards. Sealed joints provide a guarantee against the growth of mold and fungus in the space.

Warm joint

The technology of repairing seams in panel houses "warm seam" is quite new, but more effective than those given above. To carry out this work, it will be necessary to partially or completely open up the panel joints. The old sealant and insulation material is removed, and the joints are cleaned from various debris. When these works are done, hollow insulation Vilaterm is laid in the joints.

To maximize joint insulation, fill cavities with assembly foam, if at all possible. Mastic with a sealing effect or simply sealant should be used to seal the joint.

However, you won’t completely fill the joint’s cavity with this technology. A unique technology known as a "dense joint" was created to address this filling problem while accounting for all the drawbacks of various approaches.

The warm joint has been improved by this technology. It outlines how to use assembly foam and Vilaterm insulation to seal panel house joints and the area behind them.

The same method of sealing is used on the house’s horizontal grooves. After this phase of the process is finished, mastic or sealant is used to seal the joints. Therefore, cold air will still not be able to reach you through the uninsulated joints if the joints in the nearby apartments are not sealed.

Take note! At least -16 degrees Celsius should be the minimum air temperature for this kind of work. There is no law governing the maximum temperature.

You can insulate grooves without having to open them. When the outside is sealed with a strong mortar or the groove is excessively narrow, this is necessary. The next step is to drill holes in the joint’s height, with a step of 0,2-0,3 meters. Starting at the bottom and working your way up, pour the foam through the holes.

Please be aware that if the foam emerges from the hole, the joint can be regarded as sealed. The extra material needs to be taken out. Since the assembly foam fulfills this function in this instance, thermal insulation is not installed. We apply mastic on top of the cement coating. The joint needs to be sealed in the same manner to keep the walls dry.

When fixing seams in the panel house, you will only receive high-quality caulking if all the technical subtleties are followed. The work will have been in vain if something is done incorrectly. These kinds of tasks are only assigned to industrial climbers above the second floor.

When there are no obvious indications of leaks within the apartment and the joint’s surface damage is minimal, this repair technique is employed. Typically, this type of work is done right away when performing cosmetic repairs.

However, joints are waterproofed after thorough cleaning and sealing material replacement. Nevertheless, despite everything, joint insulation is not done.

Warm joint

Although relatively new, the "warm seam" method of panel house seam repair is more successful than the previous methods. It will be necessary to partially or fully open the inter-panel seam in order to complete these works. The joints are cleared of any debris and the outdated insulation and sealant are removed. Following completion of this work, Vilaterm hollow insulation is laid over the joints.

To provide the best possible joint insulation, assembly foam is inserted into the cavities when feasible. Either a sealant alone or mastic with a sealing effect should be used to seal the joint.

However, the joint cavity won’t be completely filled using this technology. Taking into consideration all the drawbacks of various approaches, a unique technology known as "dense seam" was developed to address this filling problem.

The warm joint is enhanced by this technology. It provides caulking of panel house seams using Vilaterm insulation and assembly foam, as well as the area behind it.

The house’s horizontal grooves are sealed using the same technique. After this phase of the process is finished, mastic or sealant is used to seal the joints. Therefore, cold air cannot reach you through the uninsulated joints if the joints in nearby apartments are not sealed.

Take note! It is imperative that such work be done in air that is at least -16 degrees Celsius. There is no law governing the maximum temperature.

You can insulate grooves without having to open them. When the outside is sealed with a strong mortar or the groove is excessively narrow, this is necessary. After that, you will need to drill holes every 0.2–0.3 meters along the joint’s height. The foam should be poured through the holes, working your way up from the bottom.

Keep in mind that if the foam has exited the hole, the joint can be regarded as sealed. The extra material needs to be taken out. Since assembly foam serves as thermal insulation in this instance, thermal insulation is not installed. Top off the cement coating with mastic. The joint needs to be sealed in the same manner to keep the walls dry.

When fixing the panel house joints, you can only obtain high-quality caulking if you pay attention to all the technical details. The work will have been in vain if something is done incorrectly. This kind of work is only assigned to industrial climbers above the second floor.

Typical technologies of repair and caulking of inter-panel joints

Three common repair technologies, with varying depths and scopes of work, have been developed by experts to reduce the cost of the costly caulking process:

How to perform a major repair of the inter-panel seam

Repairs involving total replacement and caulking of the waterproofing and insulation system are the most challenging. The interpanel joint must first be opened and cleaned to remove any remaining sealing layer, waterproofing, and old insulation. Employees must manually remove the outdated caulking material from a suspended bench painter’s chair using a trowel and a carpentry cutter at a height. Numerous cleaning attachments for pneumatic drills are available to clean inter-panel joints. These attachments enable the cutting of rubber and plastic, as well as white concrete, although working at heights is not always convenient.

Following cleaning, assembly foam is poured into the inter-panel joint cavity and sprayed with water. Subsequently, a tube of polyethylene foam, like Vilaterm, or polypropylene, polyurethane foam Penoflex is inserted into the joint before the foam has had time to fully expand. The insulation is rolled up and then foam is used to re-fluff the pipe. The layer of cured foam must be trimmed after it has cured in order for the sealant to stay within the bounds of the building’s facade.

Both stripping and applying sealants can be done manually or with a gun. It’s a challenging task that calls for a lot of physical strength. Squeezing an entire sealant tube into the inter-panel joint cavity with one hand is simple; however, using several dozen cans of sealant throughout the day presents a different challenge. As a result, attempt to apply sealant frequently using a trowel, the traditional method. The longevity of the inter-panel joint sealing and its quality determine how precisely and expertly a layer of sealant is applied. The service life is roughly ten years on average.

Plaster mortar should be used to seal the inter-panel joint after sealant has been applied, shielding the polymer from oxidation and freezing.

Panel house joint repair: the tools needed and who should do it. The poorly caulked seams between panels in panel houses are just one of their many issues. This may show up as a breach in the sound insulation, the growth of fungus, or wetting of the walls. Inadequate joint sealing will not only make living in the apartment uncomfortable, but it can also lead to further panel destruction as the welded joint may weaken. However, freezing and moisture seeping into the joints cause the most damage.

You insulate panel houses and fix their joints to address this issue.

These costly repairs are done by contractors when the house is being repaired.

Types of repair

Initial joint sealing and insulation are done when building panel houses. After installation is complete, insulation is inserted into clean grooves, the joint is filled with mortar, and the joint is sealed from the outside. The work is now regarded as finished, and the joints have been sealed. The panel joints’ sealing is disrupted during the building’s subsequent operation as a result of panel shifting and house shrinkage. The tenants’ actual issues start at this point.

Industrial climbers fix the inter-panel joints in panel houses. The primary goals of joint sealing are to keep moisture out of the joint’s interior and to keep the sealing materials from freezing during the winter.

Such joints will last longer than a year if the repair work was done using technology that was observed. Yes, the way the joints are sealed will determine how long the building lasts overall. Panel house secondary sealing and inter-panel joint repair will result from a combination of major and cosmetic repairs.

Technology and methods of repairing joints

Precise material selection and high quality fulfillment of the entire production technology are the primary requirements for high-quality repair work.

There are 3 main ways of repair

• Seam sealing.
• "warm joint".
• Waterproofing works.

When caulking joints, the task is carried out without requiring the primary sealant to be opened and replaced. A mastic is applied from above in this instance. When there are no obvious indications of an airtightness violation within the apartment and the damage to the joint and its outer layer is minimal, this repair technique is employed. Typically, this type of work is done right away when performing cosmetic repairs.

Nevertheless, thorough cleaning and sealing material replacement are necessary for the joints to be waterproofed. However, this joint insulation is not done at all. Use Hermaflex 127, a polyurethane one-component sealant, for joints and inter-panel joints as a general rule. This material hardens quickly and is excellent at insulating vertical joints. It can tolerate temperature fluctuations over a broad range, from -50 to +80 degrees.

It blends flawlessly with any kind of facade paint and is available in white or gray hues. Eight years is the warranty period. By using this technology to repair the inter-panel joints in panel houses, moisture can be kept out, but the cold will still be able to enter the room through the horizontally undone joints.

We’re not talking about cold here; sealing the outer joint suggests that it will only act as a barrier against moisture and water seeping inside. Use waterproofing compositions for this purpose, and fill the seams completely between the panels with assembly foam to provide an insulating effect.

Keep in mind that since the foam will be positioned between the slab, it will be shielded from UV rays. This will increase how long it lasts. Water penetration will be prevented from the boards and joints if a sealant was applied. Sealed joints provide a guarantee against the growth of mold and fungus in the space.

To provide the best possible joint insulation, try to fill the cavities with assembly foam. Mastic that has a sealing effect or just a sealant should be used to seal the joint.

However, the joint cavity won’t be filled entirely with this technology. Taking into consideration all the drawbacks of various approaches, a unique technology known as "dense seam" was developed to address this filling problem.

The warm joint is enhanced by this technology. It covers the space behind it and the sealing of panel house joints using assembly foam and Vilaterm insulation.

The same technique is used to seal the house’s horizontal grooves. After this phase of the process is finished, mastic or sealant is used to seal the joints. Therefore, cold air cannot reach you through the uninsulated joints if the joints in the nearby apartments are not sealed.

27 Sen Repair of inter-panel joints according to GOST

The primary drawback of panel houses is their quickly deteriorating inter-panel joints, which can result in the formation of cold bridges, the freezing of internal joints, and ultimately higher energy expenses. Broken panel joints also detract from the aesthetics of facades and raise the cost of apartments in such buildings. It is unclear how to correctly apply these standards in the modern era and how to repair inter-panel joints in accordance with GOST.

How to make repairs of inter-panel joints according to GOST standards

Many soft materials are now available from manufacturers in the form of tapes, round moldings, profile products, and gaskets for joint sealing and insulation. Renovators can choose from a variety of mastics as a finish, but it is not advised to use sand-cement mixtures to seal the joints because they will eventually deteriorate. Polyurethane-based mixtures are the best finishing materials for joints that require elegant and superior caulking. They form a strong exterior coating, are elastic, do not shrink much, adhere well to wall panels, and are resistant to freezing, rain, and air infiltration.

How to make the facade of the house beautiful

How to make the facade of the house beautiful, in cases where the inter-panel joints cease to fulfill the function of protection from moisture and cold penetration, as well as lose aesthetic appearance? Partial sealing or complete repair of inter-panel joints is necessary here, with opening of joints and its complete sealing. Today, to obtain beautiful facades, gray concrete panels are painted in bright colors, and often, with the use of decorative elements that turn standard houses into interesting design works. Repair according to GOST standards requires the use of standardized sealants and decorative finishes that effectively match the color of the panels in the work.
Repair of inter-panel joints is divided into several differentiated operations, which include:

Initial sealing of the joints

The joints are cleared of debris, dust, and plaster layer delamination during the work process. After that, joints are filled with assembly foam, insulation, and polymer compounds to seal chipping and cracks. joints with partial openings sealed again Problematic joint sealing areas are opened, thoroughly cleaned, and then filled with polyurethane foam. Following that, final decorative finishing and sealing with polymer water-repellent mixtures are completed.

Sealing using the "warm seam" technology

Panel joints are thoroughly cleaned, foam is inserted, insulation is layered on top, and sealing mastics are used to seal the joint closure. Joints sealed repeatedly without being opened If the joints have some minor damage, they are cleaned and covered in sealant.

SEALING OF JOINTS WITH SEALING GASKETS AND WATERSTOP TAPE

4.1. Sealing porous gaskets poroisol and gernit are used for sealing vertical and horizontal joints of external wall panels, as well as for sealing gaps between window (door) blocks and the wall structure.
4.2. Sealing gaskets made of poroizol should be used with Isol mastic. Gernit gaskets are used with KN type mastic.
4.3. Gaskets made of poroizol of rectangular cross-section should be used for sealing horizontal joints, laying them before the installation of panels of the next floor, and gaskets of circular cross-section – for sealing vertical and horizontal joints.
4.4. The thickness of gaskets used for joints should be 30 to 50% greater than the width of the joint.
4.5. Sealing of horizontal inter-panel joints should be performed in the following sequence:
a) clean the ends of the lower panels from adhering mortar and other contaminants;
b) when using poroizol, the ends of the lower panels should be primed with Isol mastic using CO-21 unit;
c) glue poroizol on the primed end strip and cover it with Isol mastic from above. After that, install the panels of the next floor on the beacon spacers. When laying sealing gaskets in horizontal joints, after installation of the above panel, it is necessary to cover the jointed edges of the panels with mastic isol, after which the gasket should be inserted into the project position, ensuring its compression along its entire length by 30 – 50%.
4.6. Sealing of vertical joints should be carried out in the following sequence:
a) clean the surfaces to be jointed from adhering mortar and other contaminants;
b) cover the surfaces to be joined with Isol mastic;
c) lay the sealing gasket and cover it with Isol mastic.
The gasket should be placed in such a way as to prevent its pulling out.
4.7. When sealing joints both during and after installation, the following requirements should be observed:
a) when applying mastic isol it is necessary to protect the surface of the panels outside the sealing zone from contamination by mastic with light shields;
b) gaskets should be installed without breaks, cutting their ends "on the ear" and gluing with mastic at the joints and intersections, with the vertical gasket on the outside.
4.8. Requirements for the sequence of works for sealing the joints with gernit gaskets are similar to those stated earlier in the paragraphs. 4.5 – 4.7 of these Guidelines.
4.9. The arrangement of vertical open joints is made in the following order. After the panels are installed, a waterstop is inserted into the vertical groove of the joint and pulled through the entire length of the joint with special pliers. The upper end of the waterstop tape is glued onto the rainproofing tooth of the panel and pressed down on top of the upper panel.
4.10. In winter, porous gaskets should be kept in a heated room until they become elastic before use. The waterstop should be stored in a warm room.

Why to treat joints in a panel house

A panel house’s joint sealing is a crucial step in the building process. It entails the filling of the spaces between the horizontal and vertical slabs. Future sealing work should also be done, particularly on older residential buildings, as the joints eventually deteriorate, lose their integrity, and need to be restored.

If this process is not followed, air and moisture will seep into the intertile joint area, causing condensation to begin. This will cause the walls to freeze and dangerous microorganisms to infest them. There will be mold and moisture in the rooms, as well as a decreased temperature. At times, the percentage of heat loss resulting from this cause can attain remarkably high figures. Sealing the joints between slabs is also a matter of aesthetics: wallpaper on cold walls will eventually peel off and the plaster will turn black, both of which are unsightly.

The facade may depressurize at any point during the house’s "life." It may result from:

• incorrect building design, deviations from SNiP;
• displacement of panel blocks due to uneven shrinkage of bearing structures;
• deformation of blocks due to strong temperature differences, intense precipitation;
• violations at the stage of construction works;
• use of low-quality materials;
• combination of materials with different degrees of elasticity;
• excessive tensioning of sealing self-adhesive tapes.

Inter-panel joints – how and with what to seal

Poorly sealed inter-panel joints are one of the issues with panel buildings. This may show up as mold growth, damp walls, or poor soundproofing.

Inadequately sealed joints not only create discomfort within the apartment but also lead to panel destruction and weaken the strength of the welded inter-panel joint. Freezing and moisture seeping into the seam cause the most damage.

Inter-panel joints need to be repaired and insulated in order to resolve this issue. These contractor-performed, labor-intensive tasks are typically scheduled in conjunction with the house’s subsequent repairs.

Types of joint repair

Panel houses have their joints sealed and insulated in the initial stages of construction. Following floor panel installation, the joint is filled with mortar, the insulation is positioned inside the clean groove, and the exterior is sealed.

The work is now complete, and the joints are regarded as sealed. The panel joints’ sealing will eventually break during building operations as a result of the house’s shrinkage and panel shifting. The tenants start to experience issues after that.

Industrial climbers are used in the process of sealing the joints in multistory panel buildings. The primary goal of panel house joint sealing is to keep moisture out of the joint’s interior and avoid freezing winterized materials sealed joints. The following materials are used to seal interpanel joints:

• sealing mastics or sealants;
• waterproofing tourniquet;
• vilatherm;
• assembly foam.

Depending on the kind of repair being done, the aforementioned materials may be used. The joints with damaged mastic are cleaned during cosmetic repair. Sealant, or sealing mastic, is the only material used if there have been no freezing or moisture leaks, and the insulation is undamaged.

Not every business and organization offering these services carries out the task in a diligent and high-quality manner. Some people still seal joints using the traditional method of sand-cement mortars. Bituminous mastic has been phased out as a sealing material by many companies.

It detracts from the building’s aesthetic in the first place, and it also causes the paint that was applied to the mastic to flake and fall off.

The insulation is changed and the joints are fully opened during major repairs. Painting and sealing are then completed.

Such joints will last longer than a year if the repair technology was used during the project. The service life of the building itself largely determines how to seal the joints in the panel house.

The secondary sealing of inter-panel joints in panel houses is the result of both major and cosmetic repairs combined.

Methods and technology of repairing joints

Using carefully chosen, high-quality materials and applying production technology step-by-step are the two main requirements for quality repair. Usually, repairs can be made in three ways:

• Seam sealing;
• waterproofing works;
• "warm joint".

The joint is sealed without having to be opened and the sealant changed. It is covered with mastic. When there are no obvious indications that the tightness of the joint within the apartment has been compromised and there is little to no damage to the sealant’s outer layer, this repair method is utilized. Usually, these tasks are completed in conjunction with aesthetic repairs.

Joint waterproofing involves thoroughly cleaning the joints and replacing any missing sealant. Joints lack insulation. For inter-panel seams and joints, one-component polyurethane sealant is typically used Hermaflex 127. This material operates over a wide temperature range (-50 °C to +80 °C) and hardens quickly, making it perfect for insulating vertical joints.

Compatible with all types of facade paints, either white or gray. Eight years of service life are assured. Using this technology to caulk panel joints will help keep them dry, but unsealed horizontal joints will allow cold air to enter the space. To keep water out of external joints, sealing is necessary.

To achieve this, waterproofing compositions are applied, and assembly foam is used to fill the joint between the panels, producing an insulating effect.

This completely encloses the foam between the panels, shielding it from UV light. This increases how long it will last. Water cannot enter the board joints because of the sealant, which shields them. Consequently, the sealed joint prevents mold and fungus from growing in the space.

For comfortable living and economical energy use, panel houses must be ensured structurally sound and energy efficient. Seam repair in these homes is an important task that needs to be done correctly and with meticulous attention to detail. Maintaining the durability and sustainability of panel house infrastructure requires an understanding of the technology underlying seam repair as well as knowing who should perform these tasks.

Panel house seam repairs are complex processes designed to close gaps and stop heat loss. Using specialty tools and materials—like caulking and sealing compounds—is essential to getting long-lasting and efficient results. The process of seam repair involves several crucial steps, including precise application, thorough cleaning, and surface preparation. Homeowners can lower energy waste and improve the thermal performance of their buildings by following these procedures.

While homeowners with basic do-it-yourself skills can handle some small seam repairs, more involved or difficult jobs are best left to trained pros. Skilled contractors have the knowledge and tools needed to complete flawless repairs quickly and safely. Additionally, hiring experts guarantees adherence to construction rules and specifications, protecting panel houses’ structural integrity and lowering the possibility of problems down the road.

Seam repair projects in panel houses require cooperation between building management, homeowners, and knowledgeable specialists. Effective communication, careful planning, and following best practices all add to the durability and general efficacy of repair projects. Stakeholders can improve energy efficiency, promptly handle seam-related issues, and give residents a comfortable place to live by cooperating.

In summary, maintaining structural integrity and energy efficiency in panel houses requires regular seam repairs. Making use of the right tools and supplies, along with hiring experts when needed, guarantees that repair jobs will last a long time and be effective. Homeowners and other stakeholders can maximize the functionality of panel house infrastructure and encourage sustainable living by working together and adhering to best practices.
