A filling method that allows for the safe extraction of steel sheet piles in close proximity to railways.

"Over 850 construction achievements" The 'GEOTETS method' ensures no underground obstacles are left due to abandonment (burial)! It minimizes impact on the surrounding area and also addresses soil contamination measures.

The "GEOTETS Method" (Simultaneous Filling Method for Retaining Material Extraction) is a construction method that allows for the safe extraction of steel sheet piles, retaining piles, and pre-cast piles even in close proximity to railways. In recent years, with the active redevelopment and elevation of railway lines, there has been a growing need to mitigate the impact on surrounding lines and facilities. In areas close to important structures such as railways, there is often a significant amount of retained soil material. This method allows for simultaneous filling from pre-installed filling pipes while extracting, addressing the voids created by the extraction. ■ Mitigation of impact on neighboring lines and surrounding facilities ■ Highly suppresses ground subsidence around the extraction area ■ Over 400 successful applications (including JR, Kintetsu, Tobu Railway, Hankyu Railway, etc.) ■ Environmentally friendly method as steel sheet piles can be reused ■ Other applications include construction in reservoirs and river embankments, soil contamination measures, and pile extraction.
