Modification to make concrete impermeable to water! Ensuring safety and security while extending the lifespan of concrete, and densifying the surface layer of concrete over the long term.
The "Inner Coat" is an inorganic permeable concrete waterproofing and protective material based on silicate, which forms a waterproof layer within concrete. By using colloidal particles that act as aggregates, the reaction products are less prone to shrinkage, maintaining effectiveness over the long term. It is envisioned as filling the micro capillary voids of concrete. The colloidal particles can be confirmed by the Tyndall effect. 【Features】 ■ No change in design ■ Environmentally friendly ■ Inorganic, thus unaffected by UV rays ■ Odorless ■ Shortened construction period *For more details, please download the PDF or feel free to contact us.

Company information
We modify concrete and joint cement to prevent the passage of water and deterioration factors by using our developed products, "Inner Coat" and "HB Seal." For civil engineering applications, we have developed "RCG Inner Silica" and the newly confirmed "RCG Inner Silica α." The coloring fades and loses color due to sunlight, so the aesthetics and landscape after construction do not change. Additionally, for exterior wall tiles that have deteriorated over time, we have started to handle the "Makuhari Newton Method," a technology that forms a strong transparent coating to prevent damage from falling exterior wall tiles to third parties. For waterproofing and deterioration prevention of concrete and tile finishes, please consult RCG Japan Co., Ltd. first.
