Without using any hardening agents, holes are dug into the ground, and crushed stone is packed into those holes to form stone columns!
The natural crushed stone pile method "HySPEED Method" is a ground improvement technique for soft ground that uses only natural materials, making it friendly to both people and the environment while being very strong. It can be implemented without issues in groundwater-rich soils, humus soils where cement does not set, and volcanic ash soils that produce hexavalent chromium, which were previously difficult to work with. It is a certified method by a major Japanese warranty company. *Available areas: Kinki and Tokai [Features] ■ Strong against seismic shocks ■ Environmentally friendly construction method ■ No waste disposal costs incurred ■ Contributes to the Earth through reuse ■ Liquefaction countermeasure method, etc. *For more details, please download the PDF or feel free to contact us.
