Sealing Compound for Waterproofing Cavities, Holes, Joints, or Cracks in Building Structures
Sealing Compound for Waterproofing Cavities, Holes, Joints, or Cracks in Building Structures
Material Description:
"Megatron Plug" is a material used for sealing cavities, holes, joints, or cracks in water-bearing voids in building structures.
The composition of the sealing compound includes modified Portland cement, a carefully selected quartz filler, and chemical additives. The setting time of the composition from the moment of water introduction to the end of setting is 45 seconds, allowing for sealing pressurized flows with high hydrostatic pressure.
"Megatron Plug" has high bond strength to the substrate, high water resistance, chemical, and corrosion resistance.
It is used for waterproofing static structures made of monolithic concrete and prefabricated reinforced concrete.
Advantages of "Megatron Plug":
Scope of Application:
Application Recommendations:
Expand and deepen the hole to a depth of at least 50 mm and a width of at least 25x25 mm to ensure the necessary strength and water resistance. The cavity should resemble the shape of a swallow's tail. Clean the inner part from weak concrete residues.
Mix a part of the dry mixture with water in the following proportions: 250 grams of water per 1 kg of dry mixture or 1 part of water to 3 parts of dry mixture by volume. The setting time depends on the water temperature and varies from 20 to 60 seconds. The final consistency of the mixture is plastiline-like mass.
Press the obtained mixture as firmly as possible into the cavity of the flow. Depending on the temperature of the concrete surface and the water filtration rate, the pressure should be maintained for 40-60 seconds. The lower the temperature of the concrete or water, the slower the setting of the solution occurs.
When tamping large cracks and voids, start from the highest point of the crack (joint, seam, junction, cavity).
Application work should be carried out at a temperature not lower than +5°C. It is recommended to treat the tamponed void and adjacent area with two layers of "Megatron Penetrating" mixture.
