TOA was established in 1958, at the early stage of high economic growth period of Japan. Sewer pipe rehabilitation with SEAMLESS LINER has become the core business for TOA in the last few years. In 2014 TOA has installed 15.000 m of its SEAMLESS LINER.

Soil and Sewers

In 1958 the first core business field was soil strengthening with chemical grouting method and contributed to the construction of underground structure such as subway transportation network. In the 1980’s, TOA entered into the second core business field of slope protection with the ground anchoring method utilizing its experice of soil strengthening technology. It introduced new methods into this field, such as PUC method, ground anchoring combined with prefabricated bearing plates for slope protection, and RING-NETS barrier made with high-tensile steel wire mesh for rock fall protection.

We are very excited to become a member of IKT, and looking forward to working with IKT and the other members.
