Cement waterproofing

High grade cement in its pure form has been used as an additional waterproofing of structures for many years. During the construction of large-scale hydraulic structures, subway tunnels and swimming pools, specially designed waterproofing concretes were used. But creating a composition based solely on mineral fillers that is easy to apply and prevents moisture penetration was an impossible task until scientists and chemists began experimenting with polymer materials. The result of these works is a modern cement waterproofing, which surpasses its analogues in terms of durability, ease of use and even price.

Such mixtures contain a binder in their composition, which is a high-quality cement of high grades, a special filler, and polymer additives that enhance the adhesion of the mixture and penetrate deeply into the surface. Crystallizing in the concrete structure, they firmly bind the base to the coating, add elasticity to the waterproofing coating and enhance the hydrophobic properties of the mixture.

The adhesion of cement waterproofing is higher than that of bitumen and even bitumen-polymer. Such compositions have excellent adhesion to concrete, brick, and plastered surfaces. At the same time, the surface acquires high mechanical strength and abrasion resistance.
Vapor permeability is a unique property of waterproofing cement-polymer solutions. This quality eliminates the occurrence of cracks, both in internal and external applications. When reconstructing buildings, this is practically the only solution.

The environmental friendliness of such formulations allows them to be used for the treatment of swimming pools and drinking water tanks.

The practicality of cement waterproofing is undeniable. Unlike pasting, it can be applied to the surfaces of the most complex shapes, it is simply applied with a brush or a spatula, and the cost is significantly lower than traditional analogues.

The durability of cement waterproofing is much higher than other types and is comparable to the duration of operation of buildings, so that surface repairs are practically excluded.

The elasticity of cement-polymer solutions is achieved by a high content of polymer components. An example of such two-component mixtures are Teknomer 200 and Teknomer 200 EX. They are used when cracks are likely to occur, and their surface strength and abrasion resistance are higher.    

The finished surface for finishing cement waterproofing eliminates the use of additional preparation and is ready for plastering, painting or laying tiles. This provides savings and eliminates the use of additional materials.

 

According to its purpose, cement waterproofing is divided into several types:

  • coating (simple or elastic)
  • penetrating 
  • repair shop

 

Coating waterproofing has a very wide range of applications. It is used to protect foundations and plinths of buildings from moisture, both from the outside and from the inside. They are used for waterproofing pools, floors, walls, balcony slabs and exploited terraces are treated. Penetrating mixtures are used for porous substrates, the solution penetrates into the structure of the material and fills the pores and crystallizes there. Repair compounds are used for joints and cracks in concrete, during the reconstruction of buildings.

Waterproofing works with cement-polymer compounds begins with the preparation of the surface for applying the mixture, it is cleaned of dust, dirt, oils and foreign substances. Often, the surface must be moistened before application. Existing cracks and seams are stitched and tightly filled with repair compounds. Next, the Teknomer 200 or Teknomer 200 EX solution must be applied with a brush or spatula, carefully rubbing into the surface, leaving no gaps, and if necessary, apply several layers.

Thus, we have made sure that cement-based waterproofing is an effective and more economical solution compared to existing solutions, and for internal waterproofing of basement floors and basements it is generally the only option.
