東和工業 Company Overview

Towa's asphalt waterproofing supports the longevity of various social infrastructures such as rooftops, tunnels, and bridges.

Towa Industry was established in 1953 with the aim of manufacturing asphalt-based corrosion protection materials for electrical cables, as well as waterproofing, dew prevention, and insulation asphalt roofing and tapes. Since then, we have advanced research and development and improvements using 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 for joints in embankments, as well as injection joint materials for roads. Additionally, we leverage our production equipment for processing such as mixing, kneading, punching, and cutting, and we conduct a wide range of contract manufacturing operations. If you are looking for partners for kneading processes, extrusion molding processes, or prototypes, please feel free to consult with Towa Industry. We also accept various packaging tasks and light work. At our factory in Itabashi, Tokyo, we respond quickly and accommodate small lot requests. Please do not hesitate to reach out to us with your inquiries.
