Based on our achievements and environmental conservation, we will continue to evolve to meet the diversifying needs and trust.
We are addressing environmental issues. As advancements in building technology, heightened awareness among residents and users, and diversification of values progress, the All-Japan Asphalt Waterproofing Business Cooperative aims for the long-term durability of waterproofing materials while promoting improvements in construction methods that respond to labor-saving, energy conservation, and resource conservation. Furthermore, taking into account safety and environmental preservation, we are conducting research to maintain and preserve the existing social infrastructure over the long term. We have developed a sheet called "Polybest," which uses "polymer-modified asphalt" that has excellent waterproofing and durability by adding polymers to asphalt, and we have developed a new construction method called "Polybest Torch Method," which involves heating and fusing with a gas burner, based on years of experience, along with "Insulation Method" and "PB Mechanical Fixing Method" suitable for renovations.

basic information
【Features】 ○ Fatigue Resistance - This is a top-quality modified asphalt roofing made by impregnating and coating a special synthetic fiber non-woven fabric core with highly modified asphalt. It is rich in rubber elasticity, adapts to the movement of the substrate, is difficult to break, and maintains waterproofing effectiveness. ○ Weather Resistance - Since it uses modified asphalt, it has excellent high and low-temperature characteristics, allowing it to withstand weather conditions and temperature changes better than conventional asphalt waterproofing. ○ Energy Efficiency and Comfortable Living Environment - By adopting insulation specifications, it protects the structure while saving energy and maintaining a comfortable indoor temperature. ○ Improvement of Working Environment and Environmental Conservation - The 'PB Mechanical Fixing Method' partially fixes with machinery and bonds only the joint parts with a torch burner, making it suitable for renovation work. ● For more details, please contact us or download the catalog.
