The widespread use of concrete for the erection of various building structures has shown that this material is unusually strong and durable. But at 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 kinds of chips and shells appear. In addition, the surfaces of concrete products begin to gather dust and crack.
Scope and composition of impregnation
To avoid dust formation and maintaining the surface in working condition, builders use such a useful chemical solution as impregnation for concrete.
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 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 by concrete grades, conditions of application and operation, the safety of the treated surface and the goals.
Polyurethane impregnation
The universal composition has only polyurethane impregnation for concrete. This one-component material is completely absorbed quickly and penetrates to a sufficient depth. Creating a particularly durable layer, such an impregnation does not interact with moisture contained in the environment, and allows you to create protection on the surface of any density level. The coating is flexible and able to withstand significant temperature changes.
In addition, it can withstand high humidity conditions. With sufficient treatment by impregnation to a depth of 3 to 5 mm, the concrete layer retains its strength under increased mechanical stresses of various abrasives for more than 10 years. It is possible to apply polyurethane impregnations on concrete at any time of the year, as they are able to penetrate to a given depth even at low temperatures.
Moisture-proofing impregnations
Each concrete structure requires protection from many negative influences, but ordinary water acts especially aggressively on the surface of cement. Even a small amount of moisture can reduce operating time to a minimum. Water, penetrating into the porous base, during freezing creates some tension, and concrete begins to crack and collapse.
Special impregnation for concrete must be present in the manufacture of structures for outdoor use. Most often, concrete coatings in the form of solid grouted surfaces or separate tiles for outdoor installation are not treated with protective compounds, which leads to their rapid wear and surface dust.
Moisture protection
A special protective composition protects the top layer of products from the destructive effects of water and maintains its appearance. In addition, corrosion protection of steel reinforcement in concrete structures takes place. Chlorides or sodium elements added to the product increase the penetration of moisture into the internal pores, can cause rust and shorten the life of the product. With such additives, specialized impregnation for concrete is simply necessary.
Chemical compositions that protect materials from moisture penetration in construction are commonly called water-absorbing agents. They not only protect structures from cracking and destruction, but also prevent the appearance of efflorescence, that is, salt stains. It is efflorescence that can cause the destruction of the outer layer of the concrete surface. Any impregnation for concrete from moisture will prevent their formation.
"Proteksil"
For dedusting and creating a special durable surface layer, the Impregnation for Protexil concrete is very effective and universal. This organic-based fluid is most often used in the organization of concrete floors in old and new industrial buildings. Low abrasion of the coating and high resistance to mechanical stress from transport allows the use of such impregnation in the construction of warehouses, in the chemical industry and in areas of high traffic.
Impregnation "Protexil" works great on new and restored mosaic floors and lends itself well to polishing. Subject to proper storage of the drug, its beneficial properties are maintained for six months. The surface covered with such an impregnation is protected for more than 7-8 years. "Proteksil" is also an excellent impregnation for concrete from moisture. Its moisture-proof and strength-enhancing properties have found great application in modern construction.
Monolith-M
Impregnation for concrete "Monolith-M" deserved special attention of builders and finishers. The use of this drug is possible both to protect old concrete surfaces, and to cover 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 product also perfectly protects the concrete coating from chemical and oily products. Such concrete impregnation is used in large trading floors, when arranging coverage on bridges, in industrial zones for loading and unloading goods, and in other similar places with a large transport load.
In addition to the above impregnations, a large number of various compositions for various purposes are used to preserve concrete surfaces. The modern market offers for sale a large number of products on a water, fluorosilicate or lime-cement basis. For example, it is used to impregnate surfaces with liquid glass, wax and resin or plastic compounds. With any treatment, you can achieve a high level of concrete security and significantly increase the duration of operation.
