Stock newspaper
Fudo Tetra <1813.T> to port and airport, fishing port, coastal, and construction company with strengths in marine civil engineering, such as artificial island. Pillars of block environments such as tetrapods also business.

In the construction only in the depth required to Katayuikabe into the ground, by the minimum necessary to caking walls that construction in the ground size, as well as suppress the rise in construction cost by reducing the amount of hardening material, method for constructing a multi-layer water barrier structures so as to shorten the construction period
(Pat.2015-187356)


Upon application to soil improvement, to reduce the constraints from the soil properties of the soil, the ground improvement method that was used fluidized sand, and it to be pumped a sufficient amount in the ground even in coarse sand as sand material
(Pat.2015-183466)

In the ground and to be able to easily construct a consolidated improvement body of Kabe-gata, special head used to soil improvement method according to the high-pressure injection mixing method for achieving even construction cost reduction of as well as to shorten the construction period, and in this soil improvement method
(Pat.2015-187352)
