It contains zero harmful solvents, making it safe for indoor work. 【Features】 - Waterproofing that withstands up to 5 atmospheres - Compatible with both "pre-application and post-application" methods - No sagging, can be applied up to 20mm thick in one go - Suitable for spray application and trowel application - No re-emulsification occurs after curing (passed Ministry of Health, Labour and Welfare Notification No. 69 water quality test) *For more details, please refer to the catalog or feel free to contact us.

"Super Flex D2" is a waterproofing material used for underground walls, various water tanks, and civil engineering structures. Its coating has crack-bridging properties and forms an excellent waterproof layer with flexibility. It is a rapid-setting polymer-cement-based coating waterproofing material. Furthermore, Super Flex D2 uses a unique special powder, which improves workability and finish quality. It conforms to Type B quality standards of the Japan Architectural Institute's guidelines for polymer-cement-based coating waterproofing construction. 【Features】 ○ Flexibility ○ Low shrinkage ○ Rapid reaction curing ○ Adhesion ○ High humidity curing For more details, please contact us or download the catalog.

"Super Flex EV" is a polymer-cement-based coating waterproofing material designed to protect architectural structures from leakage accidents caused by prolonged exposure to wind and rain. It is an advanced water-based coating waterproofing material that combines excellent durability, strong adhesion, and resilience that is tough yet has crack-bridging properties. It meets the A-type quality standards of the Japan Architectural Institute's guidelines for polymer-cement-based coating waterproofing work and has a formaldehyde emission rating of F☆☆☆☆. 【Features】 ○ Coating Performance → A coating with excellent water resistance and durability, combining toughness and elasticity not seen in conventional products. ○ Workability → Easy to apply using brushes, trowels, rollers, or sprays. ○ Adhesion → Strongly adheres to various substrates such as mortar, concrete, metal parts, asphalt waterproofing, and urethane waterproofing. ○ Substrate Treatment and Temporary Waterproofing Function ○ Safe and Secure For more details, please contact us or download the catalog.

The "TAP Grout Method" is a high-pressure injection waterproofing technique that replaces the pathways of water within concrete structures with resin. By using a TAP injection machine to continuously inject TAP grout solution under high pressure, it reduces the re-leakage that causes deterioration of the structure. In addition to its waterproofing effect, it is a groundbreaking method that improves density and durability, workability and cost-effectiveness, as well as aesthetics. 【Features】 ■ Replaces water pathways in structures with resin ■ Injects TAP grout solution using a high-pressure TAP injection machine ■ Uses O-plugs (stainless steel) *For more details, please download the catalog or contact us.

Ultra Micro Grain is an inorganic injection material primarily composed of ultra-fine particle cement derived from blast furnace slag. Due to its special powder formulation, it possesses resistance to separation in water, preventing issues such as bleeding and sedimentation. Unlike conventional inorganic injection materials, which struggle with high-pressure injection, Ultra Micro Grain enables the filling of fine voids and deep areas of concrete structures thanks to its high fluidity when used with TAP injection machines. Ultra Micro Grain can be utilized in a wide range of applications, allowing for both automatic low-pressure injection and high-pressure injection.

Recent changes in lifestyle have led to an increase in the concentration of organic acids (such as fatty acids, acetic acid, lactic acid, propionic acid, etc.) in wastewater, along with higher inflow temperatures, which have become factors in the corrosion of concrete facilities. Traditionally, corrosion prevention for concrete has been achieved by coating the concrete surface with a lining material that meets the quality standards specified in the corrosion prevention technology manual by the sewerage corporation. However, the current quality standards set by the sewerage corporation focus on resistance to sulfuric acid (inorganic acid) derived from hydrogen sulfide gas, and do not address resistance to organic acids. It is explicitly stated in the manual that the effectiveness against organic acids and similar substances has not been considered. Additionally, various cleaning agents and chemicals such as hypochlorous acid and sodium hypochlorite are mixed with organic acids in these building pits. As a result, significant corrosion of the corrosion protection layer due to organic acids has been reported, particularly in the liquid phase and especially in the water intake areas of building pits. Under such conditions, the 'Building Pit Guard' corrosion prevention system demonstrates excellent corrosion resistance performance.
