A detailed explanation of the causes of concrete deterioration! *Agents wanted!*
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.

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.
