One of the main problems of modern panel buildings is the lack of tightness of the seams. Such a "disease" can cause:
- A sharp increase in the level of air humidity (hence the formation of fungus and mold).
- Freezing or getting wet ceilings and walls of the room.
- The occurrence of drafts.
- Lowering the air temperature in living rooms.
- Bad soundproofing.
Sealing of interpanel seams is carried out using a variety of materials and using advanced technologies. The choice of joint sealing method is best entrusted to an experienced specialist. It should take into account the condition of the seams, as well as the type of panels from which the building was erected. For this, a thorough inspection of the object is carried out.
Sealing joints is divided into the following types:
1) Primary. It means laying a heater, on top of which a sealant is applied.
2) Secondary. In this case, we are talking about sealing previously sealed joints. That is, a new layer of material must be applied to the old.
3) Secondary sealing of the seams with their full opening. To begin with, the joints are cleaned of the old layer of insulation and other materials. Next, re-sealing of the seams is carried out. Only professionals can perform it quickly and efficiently.
4) Secondary sealing of panel joints with their partial opening. A certain section of the joint is selected from which the insulation layer and sealant are removed. Already new materials are used to seal the seam.
As for the cost of such a service, it will directly depend on the type, complexity and duration of the work. For example, primary sealing of joints involves the installation of insulation and other materials.
For buildings erected from sandwich panels, strength and reliability are no less important than for buildings made of reinforced concrete products. But here it is necessary to repair not the joints themselves, but the roofing seams. For this purpose, highly elastic materials and rubber seals are used.
Sealing the seams of the sandwich panels will further prevent the occurrence of leaks and drafts. In addition, you will be able to preserve the heat-insulating properties of this building material.
So, we talked about how to close joints in buildings made of reinforced concrete and sandwich panels. Without the use of reliable and durable sealants, it is also impossible to erect glass facades. In this case, special silicone-based adhesives are suitable. Such sealants are highly resistant to sudden temperature changes, UV radiation and atmospheric precipitation.
Often, joints and seams between panels have to be closed at a sufficiently high height. And this implies a serious risk. Therefore, only real professionals in the field of repair and construction technologies and high-altitude work can cope with such work.
For someone, all of these points will seem insignificant, but the moisture resistance of the entire panel will depend on them. One conclusion can be drawn from this: it is necessary to approach the selection of sealing elements with all responsibility.
