"Lakhta" - a penetrating waterproofing, which is a composition of quartz sand, cement and activating additives. The effect is achieved due to the fact that micro-voids and pores in concrete are filled with watertight joints. They are formed when the active chemical components react with the cement stone. Water must be present.

Specifications

"Lahta" - penetrating waterproofing, which has a water resistance within W10 or more. Corrosion resistance varies from 4 to 13 pH. It is impossible not to mention the high stability of the surface to dark and light oil products. It is allowed to use the composition for tanks with drinking water.

This mixture can be used in all climatic zones. Before starting work, you must ensure that the surface temperature does not fall below +5 ° C. Ultraviolet for the material we are considering has no effect. "Lakhta" is a penetrating waterproofing, which has not a very high flow rate: only 1 kg of the mixture will go for 1 m ² .

Feedback on benefits

Used "Lakhta" for waterproofing of land and underground structures. According to users, it is not toxic, it can be used on freshly-moistened and moist concrete, it is easy to use, and also forms a single whole with concrete. It can be applied on old and new concrete coatings, does not exfoliate and is not afraid of mechanical damage.

Users choose this composition also for the reason that it can be applied from the inside of the structure. Efficiency is achieved even with direct hydrostatic pressure. The use of a composition for the surface treatment of structures in which drinking water is stored will be permitted. "Lakhta" is a penetrating waterproofing, which has some additional features. For example, consumers note that this composition does not have the same high cost as analogs, but in the work it manifests itself more efficiently than clay-panel, hydrolytic and membrane systems.

Reviews about the features of use

Consumers claim that before the Lakhta application is carried out, the surface of the concrete block or concrete must be prepared. The substrate must not be damaged, it should be freed from foreign matter by the type of oil, dirt, dust, etc. This is because foreign substances can prevent the penetration and formation of crystals.

If the surface is smooth, then it should be treated with sand under high pressure, then a solution of hydrochloric acid is used, which is prepared in a ratio of 1 to 10. This will open the capillaries of concrete.

Penetrating waterproofing "Lahta", reviews about which only positive, should be applied to the prepared surface. Processing should be subjected to the place of mating, which is equipped with a 2.5-centimeter shtroba. Visible cracks need to be expanded to the same depth, their width should be 2 cm or more. The voids and cells are expanded to undamaged concrete. Users argue that before applying Lachta, the substrate must be moistened.

For reference

In addition to the above, it can be noted that the next step is preparing a solution, in which case it is necessary to act in accordance with the instruction, from which you can learn that you need to use equal parts of the dry mixture and water. The composition should be stirred regularly during application. Its scope for work should be such that the master can use it for 30 minutes.

Reviews about the features of surface treatment

Penetrating waterproofing for concrete "Lahta" should be applied with the help of spray equipment or a hard brush. Users argue that in a dry climate, light wetting is required before the second layer is applied. If it is a question of horizontal surfaces, the liquid solution should be put in one layer, use for this purpose it is possible a brush.

Consumers like that when working with ductile wet concrete, it is possible to apply Lachta by spraying the composition through a fine sieve. Then the surface to be treated is rubbed and the coating is to be wet-dried. In this condition, the surface should be left for 3 days.

Cost

For example, penetrating waterproofing, which is used for reinforced concrete and concrete structures, can be purchased for 5,200 rubles. This mixture can be used in conditions of reinforced concrete and concrete structures, as well as in rubble or brick masonry. If it is a seam waterproofing, the 25-kilogram package will cost the customer 3,800 rubles. A mixture is used for waterproofing molding joints, cracks, seams, and also communication inputs. The composition can be used for joints in prefabricated and monolithic concrete and reinforced concrete structures.

Having studied the reviews, it can be concluded that Lakhta is very popular among the similar goods today. Penetrating waterproofing (you can buy it in Moscow in many construction shops) goes on sale in several variations.

Another type is an additive to concrete. For packaging weighing 20 kg you will have to pay 1900 rubles. This material is intended for obtaining solutions that will have increased water resistance, frost resistance, strength and corrosion resistance.

Sometimes the work needs a repair base composition, which can be purchased for 1800 rubles. The material is used to restore the surfaces of brick, concrete, aerated concrete and reinforced concrete structures. This mixture is used to repair defects, the depth of which starts from 5 mm. The composition includes thixotropic, so it can be used on vertical surfaces.

Conclusion
