Megatron Seal

For a quick stoping the flow pressure when other mixture are washed with water.


Material description:

    Megatron Seal is used for a quick stoping the pressure flow, in cases where other mixture are washed with water.

    Dry mixes, consisting of special cement, silica sand granulometry certain active chemical additives are used for the rapid elimination of pressure leaks in structures made of concrete, stone, brick.

Features:

  • Short setting time (1 minute);

  • The ability to expand;

  • Eco-friendly.

  • Radiation safe.

Scope:

  • Hydro precast concrete structures (foundation blocks, panels overlap, balcony slabs, introduction communications);

  • Waterproofing of monolithic concrete structures (joints, abutment, crack, putting communications);

  • Waterproofing industrial structures (joints, abutment, crack, putting communications);

  • Hydro plants agricultural sector (joints, abutment, crack, putting communications);

  • Waterproofing of water management structures (joints, abutment, crack, putting communications);

  • Waterproofing of mining and extraction facilities (seams abutment, crack, putting communications);

  • Waterproofing treatment plants (seams abutment, crack, putting communications).

Recommendations for application:

      Mix of dry mix with water in the following proportions: 250 grams of water per 1 kg of dry solution, or 1 part water to 3 parts by volume of dry solution. The optimal water temperature is + 20 ° C. Time of hardening depends on the temperature of the water is closed from 20 to 60 seconds. Prepared composition is specified of being suchlike a plasticine.

    We carry out the expansion and deepening of the hole to a depth of at least 50 mm and a width of at least 25x25 mm to ensure the necessary strength to resist water. The cavity should look like in the form of swallow tail. See. Tamponage pressure trends.The inner part must be cleaned of residues of weak concrete. The mixture is close to a 1: 3 water to one part dry mix 3 parts by volume. The resulting mixture is mostet strongly choke flow into the cavity. Depending on the temperature of the concrete surface strength and water filtration should be continued pressure for 40-60 seconds. As lower the temperature of water is by concrete as slower the solution hardening is. Tamping is performed from a peak of crack when tamping large cracks, voids (seam joint, contiguity, voids).

   The tamponated void and adjacent areas is recommended to process with a mixture of "Megatron penetrative" in two layers. Consumption in terms of dry mixture is 1,35-1,5 kg / dm3.

Storage:

   Shelf life 18 months at a temperature of-60 to + 50º C in the original packaging is not broken.

Safety measures:

   Use safety glasses and rubber gloves in process of usage (may cause skin irritation).
