The widespread use of concrete for the construction of various building structures has shown that this material is unusually strong and durable. But with a low cost of the initial components and a large margin of safety, concrete surfaces still have the ability to collapse under the influence of climatic, chemical or mechanical factors. All sorts of chips and shells appear. In addition, the surfaces of concrete products begin to dust and crack.
Scope and composition of impregnation
To avoid dusting and keep the surface in working condition, builders use such a useful chemical solution as concrete impregnation.
The special composition significantly increases the service life of the entire structure, almost completely removes dust and improves the adhesion of concrete with subsequent paint and varnish coatings. Impregnations are used both in the construction of new structures and in the restoration of old ones. Modern industry produces several impregnating solutions of different functional orientations. They are classified according to concrete grades, application conditions andoperation, safety of the treated surface and goals.
Polyurethane impregnation
Only polyurethane impregnation for concrete has a universal composition. This one-component material is completely quickly absorbed and penetrates to a sufficient depth. Creating a particularly durable layer, this impregnation does not interact with the moisture contained in the environment, and allows you to create protection on the surface of any level of density. The coating is elastic and able to withstand significant temperature changes.
It can also withstand high humidity conditions. With sufficient impregnation treatment to a depth of 3 to 5 mm, the concrete layer retains its strength under enhanced mechanical effects of various abrasives for more than 10 years. Polyurethane impregnations can be applied to concrete at any time of the year, as they are able to penetrate to a given depth even at low temperatures.
Moisture protective impregnations
Each concrete structure requires protection from many negative influences, but ordinary water acts especially aggressively on cement surfaces. Even a small amount of moisture can reduce the operating time to a minimum. Water, penetrating into the porous base, creates some stress when it freezes, and the concrete begins to crack and collapse.
Special impregnation for concrete must be present in the production of structures for outdoor use. Most often concretecoverings in the form of integral grouted surfaces or individual tiles for laying outdoors are not treated with protective compounds, which leads to their rapid wear and the appearance of surface dust.
Moisture proof
A special protective composition protects the top layer of products from the damaging effects of water and preserves the appearance. In addition, there is protection against corrosion of steel reinforcement in concrete structures. Chlorides or sodium elements added to the composition of products increase the penetration of moisture into the internal pores, can cause rust and shorten the service life. With such additives, a specialized impregnation for concrete is a must.
Chemical compositions that protect materials from moisture penetration are usually called hydrofabricators in construction. They not only protect structures from cracking and destruction, but also prevent the appearance of efflorescence, that is, s alt stains. It is efflorescence that can cause the destruction of the outer layer of the concreted surface. Any impregnation for concrete from moisture will prevent their formation.
Protexil
For dedusting and creating a special durable surface layer, Protexil impregnation for concrete is also very effective and versatile. This organic based fluid is most commonly used for concrete floors in both old and new industrial buildings. Low abrasion of the coating and high resistance to mechanical stress fromtransport allows the use of such impregnation in the construction of warehouses, in the chemical industry and in high traffic areas.
Protexil Impregnation works great on new and refurbished mosaic floors and lends itself well to polishing. With proper storage of the drug, its beneficial properties are preserved for six months. The surface covered with such impregnation is protected for more than 7-8 years. "Protexil" is also an excellent impregnation for concrete from moisture. Its moisture-proofing and strength-enhancing properties have found wide application in modern construction.
Monolith-M
Concrete impregnation "Monolith-M" deserves special attention of builders and finishers. The use of this preparation is possible both for the protection of old concrete surfaces, and for the coating of new ones. This impregnation penetrates most deeply into the surface layer and creates a dense structure with long-term performance.
Floors treated with "Monolith-M" impregnation do not deteriorate under the influence of protectors. The preparation also perfectly protects a concrete covering from chemical and oil-containing products. Such impregnation for concrete is used in large trading floors, when organizing coatings on bridges, in industrial areas for loading and unloading goods, and in other similar places with a heavy traffic load.
In addition to the above impregnations, a large number of various compositions are used to preserve concrete surfacesfor various purposes. The modern market presents for sale a large number of products based on water, fluorosilicate or lime-cement. For example, surfaces are impregnated with liquid glass, wax and resin or plastic compounds. With any treatment, it is possible to achieve a high level of concrete protection and significantly increase the service life.
