It has been widely adopted in the reconstruction projects of the Hanshin Awaji and the Great East Japan Earthquake!
The "EP Route Pile Method" is a ground reinforcement construction method that has been widely adopted since it was used in Japan in 1980 as a protective measure for an observation deck near a shield tunnel. The cement milk used as the injection material hardens and expands, enhancing not only the core material but also the friction with the soil, promoting integration with the ground. The mesh arrangement effect of the piles suppresses soil deformation and soil flow between the piles, achieving integration between the piles and the ground. 【Features】 ■ Enables downsizing of structures ■ Ensures traffic on existing roads during construction ■ Guarantees overall stability of the structure ■ Allows reinforcement while preserving existing structures ■ Can be implemented even in sloped areas or challenging ground conditions ■ Can be executed in narrow spaces *For more details, please download the PDF or feel free to contact us.

Company information
Reinforced soil refers to the technology used to build soil vertically high or to prevent collapse when soil is excavated. It is an essential technology in Japan, which is narrow and prone to earthquakes. Hirose Reinforced Soil Co., Ltd. also engages in civil engineering consulting using these methods.
