Large-scale repair work: Inorganic penetrating concrete waterproofing and surface protection material.
Just by painting the concrete surface, a powerful waterproof protective layer is formed! Additionally, due to self-repair of cracks, it demonstrates waterproofing and deterioration prevention effects for an extended period!
The inorganic permeable concrete waterproofing and surface protection material "Inner Coat" is a method that densifies the surface of concrete over a long period. It is primarily composed of particles with a diameter of 5 to 100 nanometers, and due to the unique protective action of these fine particles, the surface layer of the concrete is modified, suppressing the infiltration of water and deterioration factors, thereby enhancing waterproofing and protective effects. We also accept large-scale repair work, so please feel free to consult us. 【Features】 ■ Improved waterproofing ■ Suppression of freeze damage and salt damage ■ Enhanced abrasion resistance ■ Crack sealing ■ Suppression of carbonation, etc. * RCJ Japan Co., Ltd. is currently seeking agents! * For more details, please refer to the PDF materials or feel free to contact us.

basic information
There is also a product called "HB Seal." It is a waterproofing material that penetrates the joint cement of exterior wall tiles and floor tiles, forming a waterproof protective layer through the generation of OH-SiOH and C-S-H gel. 【Inner Coat Mechanism】 (1) The inner coat penetrates into the voids and pores of the concrete through capillary action and diffusion. (2) The main components, sodium colloidal particles and potassium colloidal particles, block the voids and pores, reacting with calcium hydroxide inside the concrete to form C-S-H gel. (3) It reduces the diameter of the voids and pores, transforming harmful pores into harmless ones. (4) It creates dense concrete that does not allow moisture or deterioration factors to pass through. By blocking harmful capillaries, pores, and cracks, reducing pore solution, and suppressing the intrusion of deterioration factors, it forms a waterproof and deterioration protective layer, extending the lifespan of the concrete. (*Reduction of pore solution occurs because the calcium hydroxide solution reacts with the inner coat to transform into C-S-H gel.)

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.
