"Selcoat" is an inorganic permeable waterproofing material that densifies and waterproofs concrete structures. It forms a waterproof layer by blocking the capillaries of the concrete body, preventing deterioration of the concrete structure. This product has been used in various applications, including the Shinkansen elevated coating work and the coating of the industrial water tunnel in Senogawa, Hiroshima Prefecture. [Examples of Applications] - Underground painting at Hokkaido Electric Power's Makku Thermal Power Plant - Shinkansen elevated coating work - Application of Selcoat to the municipal water tank in Kamiguchi, Yamaguchi Prefecture - Coating of the industrial water tunnel in Senogawa, Hiroshima Prefecture - Coating of tunnel water distribution tanks - Application of Selcoat to firewater tanks *For more details, please refer to the PDF materials or feel free to contact us.

"Selcoat" is a waterproofing material composed of inorganic substances that penetrates the interior of concrete, chemically bonding with the main component of cement to close capillaries. By closing the capillaries, it forms a waterproof layer that prevents water penetration into the concrete. It is effective not only for waterproofing concrete tanks but also against salt damage and freeze damage. Additionally, it can be applied in a wet state without the need for thick application like waterproof mortar, providing waterproofing effectiveness at a thickness of 1.2 to 1.5 mm. 【Features】 - Closes the capillaries of the concrete structure to form a waterproof layer and prevent deterioration. - Safe for work inside tanks due to its inorganic nature. - Non-toxic and also contributes to the corrosion protection of rebar. - Can be applied in a wet state. - Available in powder form and can be mixed with water for application. *For more details, please refer to the PDF document or feel free to contact us.
