SEISHIN Co., Ltd is the General agency for SP seismic base isolation system and bD-pile in the Aichi,Mie region.

Joint Research and Development

  • Prof. Gun Buntala Sthenly, Lab. of computer methods in applied mechanics and engineering, Dept. of Architecture, School of Engineering, Nihon University.
    (Development of Calculation of the efficiency of SP Aseismic method and response analysis)
  • Kato Tribology Laboratory, Dept. of Mechanical Engineering, School of Science and Technology, Nihon University, Tokyo.
    (Development of pile-cap connection for the SP seismic base isolation system.
    Research for frictional resistance reduction among steel piles, concrete foundation and ground soil)

We worked on more than 2,500 projects including 164 public construction works.

(Our projects in the Tohoku region as of Dec. 31, 2013.)

Project List for SP seismic base isolation method & bD-pile installation in 2011-2013. Project List for Public Construction Works in 2011-2013. Project List for bD-pile installation in 2000-2010. Project List for Public Construction Works 2001-2010.

Proof of effectiveness after the great Tohoku earthquake of 2011

There were no reports of damage on buildings that had installed the bD-piles or the SP seismic isolation base system by the Tohoku region after the great Tohoku earthquake of 2011.
Field research and surveys in the stricken area also verified the effectiveness of our base isolation system.

Houses constructed before the great Tohoku earthquake.
