Protection of concrete from collapsing on the street

How sturdy and durable are concrete structures that can influence the quality and degree of waterproofing before construction. To avoid getting into the structure of the material substances which will act in a destructive way, can only well-chosen waterproofing system. They prolong the lifetime of concrete structures and reduce costs of restoration, as well as the content.

The Need to protect

Protection of concrete from collapsing on the street is necessary for the reason that this material though is very strong, but in the process of operation constantly exposed to the damaging factors, among them precipitation, chemical reagents, and industrial gases.

Sometimes the concrete is constantly in contact with water, to protect it in this case, the materials are used, ensuring high waterproofing and resistance to chemical and abrasive loads. In this case we are talking about concrete tanks in which the depth of the lesion to corrosion can reach 50 cm If not to protect the material, then he could simply turn into dust.

Varieties of materials for protection

To protect the concrete on the street used materials that prevent moisture, corrosion and also increasing durability. It is the power of gidrofobizatsii substances, which are applied by the method of impregnation. This reduces the contact angle, because the concrete is protected silicon-containing composition. The advantage of this approach is the durability and water resistance, and strength. Such substances are represented by the enamels which, under the influence of alkalis become soluble and lose their hydrophobic properties.

Protection of concrete from demolition can be carried out by a waterproof film. On the surface a layer formed of various resins, e.g., polyvinyl chloride or polyurethane. The disadvantage of this method is the low permeability.

If covering a long time exposed to steam, it will flake and crumble. To eliminate these disadvantages, you should combine the protective layer and impregnation, however, the composition must be created on the same basis. It is important to use alkali-resistant film, while the protective layer should have high vapour permeability.

Protection from destruction.

Considering the protection of concrete, you must highlight the ways that would exclude the destruction of the material. Such remedies include anti-fungal and antiseptic, as well as coating materials and impregnation. To protect the structure from destruction is possible by applying an anti-corrosion coating, insulation and impregnation.

Corrosion Protection

Corrosion occurs due to the porosity of concrete. This suggests that it is important to restrict the structure from contact with moisture and to eliminate the effects of precipitation. If this is unavoidable, the concrete should be made with a higher density, that the structure was no time.

Sometimes the material is coated with water-repellent characteristics. Protection of concrete from water method gidrogenizirovanii is the best option to prevent corrosion. The material will repel water and preserve the porosity of the structure, and to exploit the design will be a wide range of temperatures ranging from -40 to +50 °C.

Gidrogenizirovanii for corrosion protection is performed in several stages. Cement additives are introduced to increase density and control of porosity. The next step uses anti-fungal materials, as they are treated to seal the structure. To exclude the effects of moisture apply paint materials. To prevent corrosion, use strips of carbon fiber. They are perfect for those areas where the metal component structures rusted.

Water resistant

Protection of concrete previously carried out with the use of dry cement mixtures, synthetic sheets and gaskets, and roofing material. This is not enough for full protection from the water. To solve the concrete surface should be treated with a liquid with a water-repellent abilities. The coating will fill in the cracks and pores, improves the durability and reliable protection.

Protection of concrete from moisture is carried out according to a specific algorithm. At the first stage finished dry layer must be protected with a sheet of roofing felt or waterproof building material. Using bitumen emulsion processed the seams between sheets. Top-applied water-repellent coating, paint or varnish.

Using anchor sheet

For the concrete protection is now increasingly used polymeric sheet, which is located on the surface in a checkerboard pattern. It is made from high density polyethylene, indicated by the acronym HDPE. Betonosmesitel sheet used for monolithic and precast concrete objects. The device has a large number of fixation pointsthat ensures a reliable connection or adhesion to the concrete or mortar.

The shape of the anchors is formed by extrusion during manufacture, which ensures a high strength of attachment. Even under strong fluctuations of temperature and pressure optimal stress distribution ensures the preservation of the structure of the material, because the force of the impact can be caused by groundwater. Anchor sheet to protect concrete solves many problems. It creates a barrier to damage of the material, abrasive particles and chemical substances.

The Layer acts as an infiltration, eliminates corrosion and protects the material against mechanical damage that can be caused by humidity, vibration of soil and impact plant roots. The anchor sheet can be set on the surface for new construction or for rehabilitation of existing structures. Reconstruction of the finished construction eliminates corrosion and restores load-bearing capacity. A polymer sheet compensates for abrasive wear and prevents further destruction.

Installing anchor sheet

If the protection of concrete you plan to anchor sheet, it is necessary to learn the specifics of its installation. At the first stage material to cut out the size and shape of the protected surface. Canvas mounted with a space from edge to removable formwork, or induction welding using the installation discs.

In the space between the polymeric sheet and protect the surface of the poured concrete mix, which allows you to simonaityte anchoring. With the help of a extrusion welding the joints between anchor sheets are welded. The resulting seam has a 97% strength of the base material and helps to create a sealed envelope.

Using the composition VVM-M

If you pondered the question about what to cover concrete on the street for protection, as an example, can consider the composition of the brand VVM-M can be applied by air spraying and impregnation use surface brushes and rollers. The thickness of coating and the depth of impregnation is adjusted to a distance of the spray from the treated surface.

When selecting a spray gun you should prefer a device that is able to issue 2 ATM. Away from the concrete base is necessary on 30-50 cm recommended coating thickness reaches 100 microns. If you are planning to permeate the concrete, the thickness of the deposited layer equal to 3 cm Before the formation of each subsequent layer does not need to wait for the drying of the previous one. The described materials are made from domestic polymers, and inexpensive cost, because the basis of non-deficient raw materials.

Security Foundation

If you got the need for protection of the concrete at the core of the Foundation of the house, it is possible to use coating the side surfaces of spent oils and plastic film. The base can be protected with a layer of soil laid around the perimeter. Additionally, you can use foam, expanded clay or slag. This reduces the depth of soil freezing and to eliminate or reduce the impact of negative factors on the concrete.

Comprehensive protection from aggressions and moisture

In order to achieve the best effect, you can resort to using multiple technologies. This is the primary defense in which the mixing of cement is accompanied by the addition of chemical modifiers and additives.

To lock cracks, you should use sulfate substances, they help against corrosion and provide strength and durability. Secondary protection is applied to the mastic, impregnation, solutions, and biocides. An additional measure will become a protective finish, which provides for the application of plaster, installing a layer of insulation and the installation of ventilated facades.

In conclusion

Concrete is a very durable material which is known for its durability, but it is based on a multitude of pores through which moisture gets. When it freezes and kristallizuetsya, begins to increase in volume, which adversely affects the integrity of the material. But such impact is not the only one that can destroy concrete.

To prevent dusting and the further loss of strength necessary to protect the structure by adding to the solution composition of special substances, which reduce the porosity. During the operational phase surface can be protected with mastics and impregnations, which creates a kind of barrier to moisture.
