We would like to introduce a case study of the "soft ground improvement method." In this project, it was necessary to carry out embankment work on extremely soft ground with an N value of less than 1 and a high groundwater level. The extremely soft ground was not only unsuitable for construction machinery but also impassable for humans. Therefore, it was essential to ensure the trafficability (mobility) of construction machinery when performing the embankment work. By laying down a "public mesh," the surface support capacity of the extremely soft ground was reinforced, making it possible for humans to walk on it. 【Case Overview】 ■ Challenges - The ground was impassable for humans, and it was necessary to ensure the trafficability (mobility) of construction machinery for the embankment work. ■ Results - By placing embankment on the ground where the public mesh was laid, we were able to reduce the sinking of the embankment into the soft ground. *For more details, please download the PDF or feel free to contact us.

(The NETIS Registration Number: KT-230109-A) In 2015, the Ministry of Land, Infrastructure, Transport and Tourism proposed the "Vision for the Reconstruction of a Disaster Prevention Awareness Society." The content explains both soft and hard measures related to disaster prevention against water-related hazards, and among the hard measures, it indicates the development of resilient structures for river levees to withstand overflow as a crisis management-type hard measure. One of the required functions in this context is the "reinforcement of the back slope of river levees."
