Nishiyama Construction Company Ground Improvement Services

Is your important land (foundation) okay?

Our company conducts ground improvement projects using the "Ground and Safe Construction Method" (referred to as the "ACPD Method" in public works). We are committed to providing high-performance, safe, and reliable ground improvement solutions. We firmly believe that ground improvement is the only way for us, as construction contractors, to contribute to the housing industry and help eliminate substandard housing. "Since our founding, we have been involved with soil, soil types, and weak ground hundreds of times. Now is the time to demonstrate the power of soil professionals," which is why we established the ground improvement division.

Ground investigation and ground improvement services

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.
