A product range developed in the harsh environment of northern Germany, characterized by heavy snowfall and abundant groundwater.
Köster GmbH, a German company acting as a sales agent for Nippon Kutaishori Co., Ltd., is a manufacturer of excellent waterproofing and water-stopping materials. To introduce a few, the instant water-stopping mortar "KÖSTER KD2" can stop water by simply pressing it against the leak for 10 to 20 seconds. Additionally, "KÖSTER KP2in1" expands internally when injected into a leak to stop the water, while hardening in areas without leaks to provide waterproofing; it is a highly flexible polyurethane injection material. There are many other excellent products available as well. Since its establishment in 1982, Köster GmbH has been dedicated to the research, development, manufacturing, construction, and improvement of ancillary services as a specialized manufacturer of water-stopping and waterproofing materials. The product range developed in the harsh environment of northern Germany, which has heavy snow and groundwater, is actively distributed in over 45 countries worldwide and has also obtained ISO 9001 certification.

Company information
Japan's structural body treatment focuses on the inorganic materials inherent in concrete and has developed the "Inorganic Penetrating Concrete Modifier RC Gardex Series," which incorporates a unique functional catalyst. This product is an odorless, water-based inorganic surface impregnation material, resulting in minimal environmental impact and effects on human health. Focusing on "products that are friendly to structures and the environment," it not only applies to new concrete but also offers a new approach to extending the lifespan, enhancing durability, and protecting against various deterioration factors for existing concrete. We will continue to actively engage in the development of new products and aim to play a pioneering role in the field of surface impregnation materials and inorganic penetrating modifiers.
