The GEOTETS method (simultaneous filling method for soil retaining member extraction) allows for the safe extraction of soil retaining members such as steel sheet piles and H-piles, making it possible to reuse previously buried soil retaining members, thus reducing costs and considering environmental impact. By continuously filling with a specially developed filling material while extracting, this method enables the safe removal of steel sheet piles without significantly affecting the surrounding ground, contributing to site restoration. Moreover, this method can be implemented underwater wherever steel sheet piles can be extracted. We encourage you to consider the 'simultaneous filling method for soil retaining member extraction,' which enables the quick, cost-effective, and reliable reuse of previously left soil retaining members. Additionally, we will be exhibiting at the "Construction Technology Exhibition 2024 Kinki" held at Intex Osaka (Zone C, Hall 6) on November 7 (Thursday) and 8 (Friday), 2024. We sincerely look forward to your visit. 【Features】 ■ Achieves shortened construction period and cost reduction ■ Allows for close proximity construction to prevent business losses ■ High-speed simultaneous filling to suppress settlement ■ Contributes to soil contamination measures as a waterproof barrier even after soil retaining removal

When performing soil retention with temporary materials in areas close to important structures such as buried water and sewage pipes, significant impacts on the surrounding ground can occur during the extraction of steel sheet piles, often resulting in the sinking of buried pipes or business losses due to building compensation. The GEOTETS method is a technique you should know about to prevent such issues! This method simultaneously fills the void created by extraction using a filling pipe that has been pre-installed while the extraction is taking place. Under conditions where there are various ground conditions and differences in extraction machinery, it has become possible to highly suppress ground displacement after extraction, allowing for the safe retrieval of soil retention materials. 【The GEOTETS method can solve the following concerns】 ■ Want to reduce costs in nearby construction ■ Want to prevent business losses ■ Want to reduce environmental impact by reusing steel sheet piles ■ Want to perform construction underwater For more details, please download the PDF or feel free to contact us!

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.

■Close Proximity Construction [Preventing Business Loss] In areas close to important structures such as residential houses, there seems to be a lot of residual soil retaining materials. This method allows for simultaneous filling while pulling out the material through pre-installed filling pipes, addressing the voids created by the extraction. It highly suppresses ground displacement, enabling safe extraction of the soil retaining materials. ■Reservoirs and River Embankments [No Water Path Creation] In recent years, due to frequent major disasters caused by heavy rain, there has been an increase in the use of construction methods that do not create water paths in soil retaining works for river and reservoir embankments. This method can also be applied underwater. ■Soil Contamination Countermeasures [Waterproof Wall Even After Soil Retaining Material Removal] In soil contamination countermeasure works, groundwater monitoring is required for two years after the completion of the project. Therefore, it is not possible to pull out the soil retaining materials. By adopting this method, which has the function of a waterproof wall, it is possible to remove the soil retaining materials early and reduce costs. ■Pile Extraction [High-Speed Simultaneous Filling to Suppress Settlement] Initially, filling was done at a rate of 20 to 30 liters per minute. Now, it has advanced to allow for high-speed simultaneous filling of up to 140 liters in large volumes. This development achievement has made it possible to use this method for extracting large cross-section existing piles as well.

The "GEOTETS method" is a construction technique that allows for the safe removal of materials without significantly impacting the surrounding ground by simultaneously filling the voids left by continuous extraction with a specially developed filler material designed for this method. This technique can highly suppress ground displacement in sandy (gravelly) and soft ground conditions. In recent years, due to the frequent occurrence of major disasters caused by concentrated heavy rainfall, it has gained attention from river management authorities as a method that does not create water channels in temporary construction for river and pond embankments. In the field of soil contamination remediation, its implementation record is increasing as one method to block the movement of contaminants. Even in cases where large volumes of filling are required, such as with steel pipe piles, it has become possible to fill quickly and in large quantities simultaneously. 【Features】 - Construction underwater is possible. - Construction is possible in narrow spaces. - Construction can be done on both small and large scales. - The filling amount can be controlled according to the amount of adhering soil. 【Disaster Recovery Response and Emergency Temporary Measures】 - Steel sheet piles and H-piles can be reused, providing a proven method to alleviate material shortages in temporary construction during large-scale disasters. - It is cheaper than leaving materials in place (we have set a low price!).

The "GEOTETS Method" is a unique construction technique that allows for the safe extraction of steel sheet piles, retaining piles, and pre-cast piles. In the area surrounding Sendai Airport, which suffered significant tsunami damage, multiple pump stations were constructed as part of recovery work to enhance drainage functions associated with the installation of a tsunami defense line. The approximately 5 km long pipeline connecting to the pump stations was in close proximity to residential areas and buried pipes, leading to the adoption of this method to prevent business losses due to the extraction of steel sheet piles. The main reasons for the adoption of this method are as follows: ■ Steel sheet piles can be reused, making it an effective means in an environment of material shortages following the earthquake. It is an environmentally conscious construction method. ■ It can highly suppress subsidence in the surrounding ground during extraction. ■ It can reduce costs compared to leaving steel sheet piles in place. Subsequent technological developments have increased the filling speed to more than twice that of the time during the earthquake recovery, shortening the construction period. As a result, significant cost reductions were achieved. *For more details, please download the PDF or contact us.

When performing earth retention using temporary materials in areas close to important structures such as residential buildings and underground installations, significant impacts on the surrounding ground can occur during the extraction of earth retention piles (such as steel sheet piles or H-piles), often leading to business losses such as building compensation. Without an effective solution, there was no choice but to leave the earth retention piles in place, causing difficulties for many stakeholders. This method simultaneously fills the void created during extraction by pulling from pre-installed filling pipes. Under conditions with a variety of ground conditions and differences in extraction machinery, it highly suppresses ground displacement after extraction, allowing for the safe retrieval of earth retention materials. In recent years, due to frequent major disasters caused by heavy rainfall, this method has seen an increase in usage as a unique solution for earth retention work on river and pond embankments that does not create water channels. It contributes to cost reduction in proximity construction, prevention of business losses, and reduction of environmental impact through the reuse of steel sheet piles. This method can also be applied underwater. *For more details, please download the catalog PDF or feel free to contact us.*
