Waterproofing technologies

Types of waterproofing

• Cement waterproofing.

• Polymer waterproofing.

• Bituminous waterproofing.

• Roll waterproofing.

There are two types of cement waterproofing: one-component and two-component.

One-component cementitious waterproofing

• Penetrating waterproofing for concrete.

• Coating waterproofing for mineral substrates.

Penetrating waterproofing for concrete

Penetrating or penetrating waterproofing is a dry mixture that consists of cement, sand and chemical additives.

Penetrating waterproofing method

On a wet base, a mixture previously mixed with water is applied in the form of thick sour cream.

Penetrating waterproofing properties

• On the surface, an armoring layer with a thickness of 1-2 mm is formed, which, 4 hours after application, can already retain the penetration of moisture. Chemically active substances penetrate into the body of concrete, which react with water, forming water-insoluble, but vapor-permeable compounds (crystals), which seal micropores in concrete, up to 0.4 mm.

• Consumption: 2-3 kg/m2/2-3 layers.

• After setting and curing, the material forms a strong but tough coating. Therefore, it is not recommended to apply on substrates that are subject to dynamic loads and temperature changes.

Scope of penetrating waterproofing

• Basements.

• Treatment facilities.

• Fire tanks.

• Drinking tanks.

• Floor waterproofing.

• Wall waterproofing, etc.

Important : penetrating waterproofing can be applied to all mineral substrates on which it forms a protective coating (concrete, screed, plaster, brick, aerated concrete, etc.). For the penetration of chemically active substances into the base body, the presence of cement in the surface structure (cement-containing bases) is required.

Coating waterproofing for mineral substrates

Coating cement waterproofing is a dry mixture, cement-based, with the addition of fine sand and chemical additives.

Coating waterproofing method

Apply to damp substrate with a brush, trowel or spatula.

Coating waterproofing properties

• It forms a hard armor layer on the surface, which can constantly work on positive water pressure, and on negative pressure, up to a certain time, it all depends on the pressure of moisture.

• Consumption: 2-5 kg/m2/2-3 layers.

• Basically, they are used on surfaces that are not subject to strong dynamic loads and temperature changes.

Scope of application of coating cement waterproofing
