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 repair). By modifying the base concrete (substrate concrete) and then applying surface coating materials and cross-section repair materials, it provides double protection for the concrete surface and its 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 implementing preventive maintenance and longevity measures. ■ The repair effect 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 deteriorating factors (moisture, chloride ions, carbon dioxide). ■ "L-OSMO Solidified Type KK" is a solidified lithium silicate-based surface impregnation material that contributes to preventive maintenance and longevity of existing concrete structures. - It is the optimal material for modifying base concrete (substrate modification). - The reactive silicate-based surface impregnation material can modify concrete that has become neutralized and is unsuitable for application.
