Capable of handling temperature changes from low to high! Seamless construction method without joints.
The "Ast Mark Method" is a waterproof construction technique that involves bonding polymer-modified asphalt, which cures at room temperature, with reinforcement materials at room temperature. It can ensure water tightness without creating joint sections, even around complex shapes. Additionally, depending on the scale of the project, it can be completed in one day, allowing for labor-saving in the work process. 【Features】 ■ Responds to temperature changes from low to high ■ Maintains stable physical properties ■ Solvent-free, so no special ventilation or protective gear is required ■ Labor-saving in the work process ■ Can be completed in one day depending on the scale of the project *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Towa Industries was established in 1953 with the aim of manufacturing asphalt-based corrosion protection materials for electrical cables, as well as waterproofing, dew prevention, and thermal insulation asphalt roofing and tapes. Since then, we have advanced research and development and improvements with our unique technology, producing modified asphalt roofing materials for waterproofing applications in construction, civil engineering, and bridges. Utilizing research results on the waterproofing, anti-corrosive, thermoplastic, electrical insulation, and shock-absorbing properties of asphalt, we manufacture sealing materials for waterproofing around oil tank bases and joints in embankments, as well as injection joint materials for roads. Additionally, we leverage our production facilities for processing such as mixing, kneading, punching, and cutting, and we offer a wide range of contract manufacturing services. If you are looking for outsourcing for kneading processes, extrusion molding processes, or prototypes, please feel free to consult with Towa Industries. We also accept various packaging and light work tasks. Our factory in Itabashi, Tokyo, can handle small lot orders and provides prompt responses. Please do not hesitate to reach out with your requests.
