The main causes of "concrete deterioration" are the presence of capillaries (porous bodies) and the existence of pore solutions. Deterioration factors such as moisture, carbon dioxide, and chloride ions in the atmosphere infiltrate through capillaries and, using pore solutions as a medium, undergo chemical reactions and diffusion. It is important to densify the capillaries and reduce the pore solutions. In particular, pores larger than 50 nm (macro-pores) are said to be problematic as they allow for easier infiltration of deterioration factors. By applying our "Inner Coat" and "RCG Inner Silica," we can transform these macro-pores into harmless pores, thereby suppressing the infiltration of deterioration factors. *For more details, please refer to the external link page or feel free to contact us.

The "Inner Coat" is a method for densifying the surface of concrete over a long period. This product is primarily composed of particle colloids derived from nanochemistry. When applied to concrete, it penetrates internally, filling voids and pores with particle colloids, which react with calcium hydroxide to form C-S-H gel. By applying the Inner Coat while maintaining the original design of the concrete, it transforms the concrete into a water-resistant material. Additionally, the synergistic effect of the physical actions of the particle colloids and chemical reactions can protect the surface layer of the concrete and extend its lifespan. 【Features】 ■ Densifies the surface of concrete over a long period ■ Main component is particle colloids (sodium silicate, potassium silicate) ■ Reacts with calcium hydroxide to form C-S-H gel ■ Maintains viscosity while enhancing diffusion capability ■ No peeling or lifting, providing long-term effectiveness ■ Good workability and reduced construction time * RCJ Japan Co., Ltd. is currently seeking distributors! * For more details, please refer to the PDF materials or feel free to contact us.

Our company handles waterproofing materials that are effective for various applications such as concrete structures, floor tiles, and bridges. "Inner Coat" is a waterproofing material that contributes to the longevity of concrete. The main component, particle colloid, penetrates and acts internally, modifying the surface layer of the concrete and powerfully preventing the intrusion of water and deterioration factors. Additionally, "HB Seal" for exterior walls and floor tiles penetrates the joint cement to form a waterproof protective layer. This gradually transforms into a hydrophilic film, exhibiting excellent anti-soiling effects by preventing moisture and deterioration factors from passing through. <Features of Inner Coat> - The self-repairing function for cracks ensures long-lasting waterproofing and deterioration prevention effects. - Enhanced penetration ability compared to our conventional products. <Features of HB Seal> - The transparent coating maintains the aesthetic quality of tile finishes and exposed concrete surfaces. - Resistant to UV effects, providing long-lasting effectiveness. ★ We are currently offering materials that include information on modification effects, case studies, and application procedures!

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.

We would like to introduce the mechanism of the "Inner Coat" that we handle. This agent penetrates into the voids and pores of concrete through capillary pressure and concentration diffusion. The main components, colloidal sodium and colloidal potassium particles, block the voids and pores, reacting with calcium hydroxide inside the concrete to form C-S-H gel. Due to the physical action of the colloidal particles, it is effective even on existing concrete with low calcium hydroxide content. Subsequently, it modifies the concrete into a dense structure that does not allow water or degrading factors to pass through, forming a stable and powerful waterproof protective layer. 【Features】 ■ Waterproof guarantee ■ Years of construction experience ■ No change in design ■ No peeling or bubbling; can be reapplied during renovation ■ Durability of approximately 15 to 20 years *For more details, please download the PDF or feel free to contact us.

The unique colloidal technology of RCG Japan Co., Ltd. can be confirmed by the Tyndall effect.
