We provide accurate and high-quality ground information that takes into account the ground characteristics and peculiarities of the survey area.
We provide a one-stop service from the planning and implementation of survey projects to the preparation and submission of reports, in collaboration with various departments within our company and partner companies. Additionally, we offer a range of services beyond just boring surveys, allowing us to provide complex proposals tailored to our customers' needs. 【Survey and Testing Contents】 ■ Boring Surveys ■ Sounding ■ Sampling ■ Freezing Sampling (please refer to detailed information) ■ Indoor Soil Testing ■ In-situ Testing ■ Creation of Input Seismic Motion for Design (please refer to detailed information) We conduct surveys for high-rise buildings, leisure facilities, buried cultural properties, and energy-related facilities such as power and oil, with over 2,000 survey achievements annually. We have our own testing laboratories in Kanagawa Prefecture, Ibaraki Prefecture, and Osaka Prefecture, where we conduct soil tests on physical properties, strength, and deformation characteristics of soil samples collected from boring surveys. Please feel free to contact us if you have any requests. *For more details, please download the PDF or contact us.

■Frozen Sampling To collect high-quality samples with minimal disturbance, it is necessary to select an appropriate sampler based on the condition of the target ground. There are five methods established as standards by the Geotechnical Engineering Society for samplers, but our company utilizes a patented in-situ frozen sampling method, enabling the collection of high-quality samples from sandy and gravelly soils.

■Creation of design input seismic motions for seismic design of new buildings and safety evaluation of existing buildings. To create the "site wave" for design input seismic motions, it is important to evaluate "source characteristics," "propagation path characteristics," and "ground amplification characteristics." In particular, regarding ground amplification characteristics, our company, as a professional in ground investigation, will conduct proper evaluations based on surveys and provide appropriate design input seismic motions.
