Evolution of asphalt waterproofing developed with coexistence with nature in mind.
We have realized the ASFIT waterproofing method, which is an evolved version of the highly reliable hot asphalt waterproofing method. In addition to high performance, high quality, and workability, we are committed to activities that contribute to the reduction of carbon dioxide emissions from production to construction. While leveraging the excellent characteristics of the hot asphalt waterproofing method that we have cultivated over many years, we will contribute to the effective use of limited regional resources.

basic information
Overview of ASFIT Waterproofing Method - A modified asphalt sheet produced in a factory using ultra-high-grade asphalt and strong synthetic fibers is applied at room temperature. Additionally, without using a melting kettle, the modified asphalt sheet is laminated with asphalt for adhesion that has been melted using a burner to form a waterproof layer. - A second layer of modified asphalt sheet is applied on top of the previously installed modified asphalt sheet using a room temperature method, by heating the surface of the lower sheet and the back of the upper sheet with a burner for adhesion.
