We have adopted an automatic testing machine for the ground investigation machine, enabling ground surveys.
Our Ground Improvement Department conducts ground surveys and ground improvement work. In ground surveys, we can measure up to a depth of 10 meters using the Swedish sounding test, unless we encounter very hard ground or other reasons that prevent penetration. We also offer the "HySPEED Method," a ground improvement technique for soft ground that is very strong and environmentally friendly, using only natural materials. Additionally, our company is involved in civil engineering slopes, construction, crushed stone production, and industrial waste disposal.
