This system enables waterproofing methods tailored to various needs through a combination of six basic construction methods and two types of waterproofing materials, along with a variety of finishing materials, reinforcement materials, and primers that possess diverse performance characteristics. The waterproofing materials used are "Art Proof U-TWOα," which is free of specific chemical substances (non-formulated), and "Art Proof U-1," which is classified as non-applicable for specific chemical substances. 【Basic Construction Methods】 ■ Public Building Construction Methods ・X-1 Method / X-2 Method ■ General Methods ・AUS / AUC Method ・AU / AUG Method *For more details, please refer to the PDF materials or feel free to contact us.

"Art Proof U-TWOα" is a two-component polyurethane waterproofing material that has improved environmental compatibility with "non-applicable specific chemical substances," "TX-free," and "F☆☆☆☆" ratings. It does not contain lead or chromium compounds, toluene, or xylene. It does not use any of the 13 substances identified by the Ministry of Health, Labour and Welfare as causes of sick house syndrome. It meets the quality standards for building coating waterproof materials JIS A 6021 for high elongation polyurethane rubber type (formerly Class 1) and exhibits excellent waterproof performance. 【Features】 ■ Non-applicable specific chemical substances ■ Environmentally hormone-free ■ Lead, chromium compounds, toluene, and xylene-free ■ Complies with indoor concentration guidelines for the 13 substances by the Ministry of Health, Labour and Welfare ■ Provides reliable waterproof performance *For more details, please refer to the PDF materials or feel free to contact us.

"Art Proof U-1" is a single-component polyurethane waterproofing material that improves environmental compatibility with "non-applicable specific chemical substances," "TX-free," and "F☆☆☆☆" ratings. Being a single-component type, there is no need to mix a main agent and hardener like in two-component types, which enhances work efficiency and reduces the generation of used cans. It contains no organic solvents and has minimal odor during curing, making it environmentally friendly. 【Features】 ■ Non-applicable specific chemical substances ■ No need for measuring, mixing, or stirring ■ Environmental impact can be halved ■ Environmentally conscious materials *For more details, please refer to the PDF document or feel free to contact us.

"Art Proof FR" is a robust waterproofing method that features a waterproof layer (FRP layer) made by impregnating soft polyester resin into glass mat. Since it does not require protective concrete, it weighs approximately 1/50 compared to conventional waterproofing, reducing the burden on the building itself. This allows for shortened construction periods and cost reductions. Thanks to its excellent chemical resistance, it is also resistant to acid rain, and maintenance can be easily performed even if issues arise in the waterproof layer. 【Features】 ■ Strong waterproofing effect ■ Reduces burden on the building ■ Shortened construction period and reduced costs ■ Resistant to acid rain ■ Easy maintenance *For more details, please refer to the PDF document or feel free to contact us.

The "Art Proof FR Method" is a waterproofing technique that leverages the strong water resistance, corrosion resistance, and impact resistance of FRP characteristics, allowing for a variety of molded products to meet diverse needs. "Art Proof FR-BN" is a fireproof method that can be applied not only to concrete but also to wooden structures. It has received certification from the Minister of Land, Infrastructure, Transport and Tourism, as well as approval for the "flying ember performance test" for roofing materials. 【Specifications】 ■ Topcoat FR-BN with aggregate: 0.3 kg/m² ■ Art Proof FR-BN sealing material: 0.8 kg/m² ■ Chop mat #380 + Art Proof FR resin: 1.4 kg/m² ■ Chop mat #380 + Art Proof FR resin: 1.4 kg/m² ■ Primer U + NB powder: 0.2 kg/m² *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Art Proof" products. Starting with the "FRP-based Coating Waterproofing Method," which excels in durability, substrate adherence, and impact resistance, we also offer the "Polymer Cement-based Coating Waterproofing Method," which is low-odor and suitable for renovations in living spaces, as well as the aesthetically pleasing "Asphalt Waterproofing." Please choose according to your application. 【Product Lineup】 ■ Urethane-based Coating Waterproofing Method ■ FRP-based Coating Waterproofing Method ■ Polymer Cement-based Coating Waterproofing Method ■ Asphalt Waterproofing *For more details, please refer to the related links or feel free to contact us.

The "Veranda/Balcony Waterproofing Repair Kit" is a single-use type that minimizes waste, and all materials can be applied using a roller or brush. It allows for waterproofing repairs over existing waterproofing materials (FRP, urethane, PVC sheet waterproofing) using a dedicated primer specification. The waterproofing material is a one-component type that does not require mixing and does not contain substances like toluene or xylene that can cause sick house syndrome. Additionally, the entire process can be completed in one coat and three steps, allowing for a shortened construction period. 【Features】 ■ Single-use type for 5m² with minimal material waste, no need for subdividing ■ One-component type with no concerns about mixing or curing issues ■ Not subject to the Specific Chemical Substance Hazard Prevention Regulations ■ All processes can be done with a roller or brush ■ Completed in just three steps *For more details, please refer to the PDF document or feel free to contact us.
