As a high-performance waterproofing material for construction that utilizes the properties of polyurethane rubber with excellent weather resistance and durability, it contributes to maintaining comfortable spaces, improving living environments, and extending the lifespan of buildings. 【Features】 - Excellent weather resistance and durability in polyurethane waterproofing methods - Stable physical properties *For more details, please refer to the catalog PDF.

This is a revolutionary one-component polyurethane rubber-based wall decorative waterproofing material developed independently based on years of accumulated polyurethane technology. It does not allow water to pass through but does allow water vapor to pass, preventing swelling and peeling of the coating due to moisture in the substrate, and preventing condensation and mold growth inside the building. Additionally, it helps prevent the neutralization of concrete and the rusting of rebar, thereby improving the durability of the building. 【Features】 ■ Does not contain specific chemical substances ■ Excellent crack-following ability for substrates ■ Excellent cold resistance, heat resistance, and weather resistance ■ Excellent water vapor permeability ■ Prevents freeze damage and salt damage ■ Adheres well to various substrates *For more details, please refer to the catalog PDF.

This is a composite waterproofing method that combines a one-component urethane with high-durability one-component urethane, featuring durability, cost-effectiveness, and design aesthetics. By using high-performance, high elongation, and high-strength resins, it achieves excellent durability and abrasion resistance. Being a one-component system allows for a wide range of application methods, including manual application, machine application, and pumping. By combining two one-component urethanes, with low-modulus urethane (DP One Guard Zero) used in the lower layer and high-durability urethane (DP One Guard NEO) in the upper layer, it offers excellent substrate followability, making it resistant to cracking and providing advanced durability to withstand external impacts from vehicle traffic. 【Features】 ■ Durability and abrasion resistance ■ Shortened construction period through machine application (spray equipment) and pumping ■ Improved safety and security for workers and surrounding people during construction *For more details, please download the PDF or feel free to contact us.

It has been about half a century since polyurethane coating waterproofing materials appeared in the construction market. Responding to changes in the times and society, polyurethane coating waterproofing materials have continued to evolve. Currently, a significant challenge of modern times is the labor shortage in the construction industry, which has already become apparent. This issue affects not only general contractors and specialized construction companies (waterproofing contractors) but also clients, and it is becoming increasingly serious. Now, an important mission for us manufacturers is to propose products and methods that can contribute to alleviating the shortage of skilled workers. The one-component polyurethane coating waterproofing material, which we began selling in 2012 and contains no specific chemical substances, has demonstrated features such as excellent environmental performance, improved construction efficiency, ensured construction quality, and reduced waste cans, as it does not require mixing and stirring like two-component systems. Furthermore, the unique ability to pump one-component systems has also improved workability, and we are continuously pursuing enhancements in this area. *For more details, please refer to the catalog PDF.*

This is a super-fast curing polyurethane waterproofing material that does not contain toluene or xylene, and is free from specific chemical substances. It forms a robust polyurethane coating waterproof layer due to its excellent elongation performance and high tensile strength. Because it cures super-fast, it is less likely to sag on vertical surfaces, and sufficient film thickness can be secured even on uneven or wavy shapes. 【Features】 ■ Significantly shorter curing time allows for reduced construction periods ■ Less likely to sag on vertical surfaces, ensuring sufficient film thickness even on uneven or wavy shapes ■ Enables construction in areas where traditional polyurethane waterproofing was difficult ■ Not affected by external temperatures, ensuring stable properties after curing ■ Constant material discharge allows for high-precision spray application *For more details, please refer to the catalog PDF.

The "Re-Roof System" is a roofing renovation method that combines a special thermal insulation reinforcement layer, ultra-fast curing polyurethane, and a heat-insulating top coat to create "waterproofing and reinforcement effects" as well as "heat insulation and thermal insulation effects" for slate and metal roofs. It protects important equipment and stored items from leaks and roof damage while achieving savings on air conditioning costs. This system demonstrates excellent waterproofing due to the suppression of thermal behavior through heat insulation effects and a thick coating of high-strength polyurethane waterproofing material that complies with JIS standards. 【Features】 ■ Waterproof performance that protects equipment and stored items ■ Reinforcement and prolongation effects for roofing materials ■ Indoor temperature reduction effects due to thermal insulation and heat insulation performance ■ Excellent soundproofing performance that reduces the sound of rain *For more details, please download the PDF or feel free to contact us.

The "Get System" is a system that forms a waterproof layer by atomizing ultra-fast curing urethane through a collision agitation method combined with compressed air. It has succeeded in reducing the specific gravity (lightweight) of urethane waterproofing, allowing for the formation of a thicker coating while using the same amount compared to conventional ultra-fast curing urethane. It ensures physical properties that exceed the standard values of JIS A 6021, combining reliability and cost-effectiveness, and significantly expands the possibilities of urethane waterproofing through various additional performance features. 【Features】 ■ High coating performance (pinhole suppression effect) ■ Excellent sound absorption ■ Added heat insulation performance *For more details, please download the PDF or feel free to contact us.

"Green Place" is a waterproof system specifically designed for rooftop greening, capable of accommodating various substrate shapes, including new constructions and renovation substrates. Its robust waterproof layer provides excellent root resistance. The seamless and high-density waterproof coating demonstrates leak-proof performance even under high water pressure. Additionally, the waterproof layer is lightweight, at just a few kg/m², and thin, which means it does not impose structural burdens compared to conventional methods. 【Features】 ■ Substrate adaptability ■ Root resistance ■ Seamless ■ Lightweight ■ Crack resistance *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Waterproofing for Rooftop Greening + Rooftop Greening System." The "Waterproofing for Rooftop Greening" is a composite waterproofing developed specifically for rooftop greening, forming a robust waterproof layer that excels in root resistance, eliminating concerns about penetration by plant roots or damage from bacteria and chemicals. Additionally, the "Rooftop Greening System" can accommodate a wide range of plants, from grass to low and medium-sized trees. Its modular design allows for quick installation, enabling the rooftop of a building to be covered in greenery in just one day. 【Features of Waterproofing for Rooftop Greening】 ■ An ideal waterproofing solution for greening that meets all performance requirements ■ Lightweight and short construction period due to the absence of a protective layer ■ Excellent design quality *For more details, please download the PDF or feel free to contact us.
