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.

Moreover, TOA also recognized the potential growth of rehabilitation and maintenance of infrastructure, and entered into the third core business field of underground pipeline rehabillitation. It has introduced many new technologies such as SEAMLESS LINER (UV curing CIPP liner), SNAP LOCK (partial repair method of joints and cracks), SmartBall (water leakage detection with acoustic emission), ICE PIGGING (pipeline cleaning with slush ice) and PRIMUSLINE (high-strength flexible hose) into this business field in Japan.
