Mother material concrete modification method (combination of surface impregnation method and surface protection method)
Please use the solidification-type silicate-based surface impregnation material "L-OSMO Solidification Type KK" as a substrate modification agent for surface protection methods.
This is a repair method that uses a solidified silicate-based surface impregnation material for substrate modification in surface protection methods (surface coating and cross-section restoration). By modifying the base concrete (substrate concrete) and applying surface coating materials and cross-section restoration materials, it provides double protection for the concrete surface and the exterior (both inside and outside), extending the lifespan of existing concrete structures. ■ Preventive maintenance and longevity measures can be implemented without significantly increasing the budget. By applying the solidified silicate-based surface impregnation method in addition to conventional repair methods, it is possible to keep costs down while ensuring preventive maintenance and longevity measures. ■ Repair effects can be expected to last for a long time. Even if the surface coating materials (such as polymer cement mortar and paint) peel off, the dense protective layer inside the concrete suppresses the intrusion of deterioration factors (moisture, chloride ions, carbon dioxide). ■ "L-OSMO Solidified Type KK" is a solidified lithium silicate-based surface impregnation material that contributes to the preventive maintenance and longevity of existing concrete structures. - It is the optimal material for modifying the base concrete (substrate modification). - Reactive silicate-based surface impregnation materials can modify the concrete in the surface layer that has become neutralized and is not applicable.

Company information
Rinac OSMO Co., Ltd. is a leading company that has developed a solidified lithium silicate-based concrete surface impregnation agent, L-OSMO Solidified Type KK, which has been confirmed to be effective with neutralized concrete for the first time in Japan (Patent No. 4484872). L-OSMO Solidified Type KK is also a pioneer in the field of concrete modification materials. As the importance of infrastructure maintenance increases, we have developed a solidified silicate surface impregnation agent that can be combined with various surface protection materials (Patent No. 7311215). The unique feature of densifying and modifying the concrete surface layer (a few millimeters from the surface) extends the lifespan of concrete structures.
