penetrating waterproofing is composed of cement, silica sand and activating additives. Waterproofing effect is achieved by filling pores and mikropustot concrete vodonerastvorimymi compounds, which result from the reaction of the active chemical components of cement stone, concrete, in the presence of water.

Scope:

used for waterproofing of underground and surface structures.

Advantages material Lahti

• not toxic;
• Easy to use;
• can be used on wet or svezhezalitoy concrete surface, both old and the new concrete;
• becoming a whole with concrete;
• not afraid to mechanical damage, does not flake off;
• can be applied to the inside of the design;
• It is effective for direct high hydrostatic pressure;
• allowed to surface reservoirs designed to store drinking water;
• In general, more effective and less costly than hydrolytic, membrane, glinyanopanelnye and other systems.

  mechanism pronikayuschey waterproofing

  mixed with water of pronikayuschey waterproofing applied to concrete. Active components pronikayuschey waterproofing enter into a chemical reaction with cement stone inside the concrete structure with the formation of insoluble crystals. These crystals block capillaries and mikrotreschiny, while displacing water. The process occurs in all directions: as a current of water, and against. Thus, the concrete becomes impermeable to water and other liquids from any direction. The growth of crystals in the absence of water stops and restarts when it becomes available, developing in depth the design process of compacting concrete patterns. Thus, Lahti penetration becomes an integral part of the concrete, forming a single solid and durable structure.

  Instructions for use

  Training grounds

  • surface of concrete or concrete block should not have structural damage, should be free from any foreign matter (dust, dirt, oil, etc.) that may prevent the infiltration of material and education of crystals. Smooth the surface to be processed sand under high pressure, then the solution of hydrochloric acid (1:10) to open the capillaries of concrete. In the field pairings prepare shtrobu to a depth of about 2.5 see visible cracks widen to a depth of 2.5 cm and width of not less than 2 cm cells and cavities must be cleared before the undamaged layer of concrete. Before causing material surface wet;
  • Preparation of solutions;
  • Solution prepared on the basis of the ratio of one volume of water per volume of dry mixture;
  • while using the solution must be regularly agitate. It should produce a solution in the quantities that can be used within 30 minutes.

    Surface

    Waterproofing sprayed
    • stiff brush or equipment for spraying;
    • In dry climates require slightly damping to cause a second layer;
    • At the horizontal surface of concrete grout is applied to pronikayuschey Lahti 1 layer rigid brush, brush or pnevmopistoletom. At the wet plastic concrete powder Lahti pronikayuschey caused by spraying through the small screen, and then treated surface zatiraetsya brush. Coverage is subject to "drying wet" for three days.

      device horizontal waterproofing

      In
      • masonry checker Buryats hole diameter of 25-32 mm at an angle of 30-45 °. The distance between the horizontal hole 250 mm. The depth of drilling - at least 2 / 3 the thickness of the wall;
      • Proburennye hole washed with water (for construction soak moisture) and filled with cement-sand mortar under pressure to 0.5 MPa;
      • then re-hole drill and fill out the liquid mixture Lahti pronikayuschey.
