Ground Investigation: Survey services related to civil engineering and construction work.
We conduct civil engineering geological surveys, disaster prevention surveys, environmental impact assessments, and underground resource investigations.
The geological surveys conducted by Japan Physical Exploration Co., Ltd. can be broadly classified into three categories: civil engineering geological surveys, disaster prevention surveys and environmental impact assessments, and underground resource surveys. These classifications are divided according to the purpose of the surveys, and civil engineering geological surveys are further subdivided based on the target structures. Japan Physical Exploration Co., Ltd. proposes and implements appropriate survey methods based on the purpose of the survey and the target structures. 【Ground Surveys】 ○ Civil Engineering Geological Surveys → Roads, railways, dams, rivers, airports, ports, buildings, soft ground ○ Disaster Prevention Surveys and Environmental Impact Assessments → Landslides, active faults, slopes, volcanic gases, deep underground structures, etc. ○ Underground Resource Surveys → Hot springs, mineral deposits, groundwater For more details, please contact us or download the catalog.

【Survey Methods】 ○Boring Survey → A fundamental survey method to understand the geological conditions beneath the ground. ○Tunnel Elastic Wave Survey → At locations with thick soil cover, elastic waves are used to understand deeper geological conditions, with vibration generated using blast holes at the ends of side lines. ○Hydrological Survey → Investigates the impact of construction work on surrounding areas. ○Electrical Survey for Waterway Tunnel Location → A survey method that allows for understanding the distribution of underground resistivity. ○Structural Deformation Survey → Investigation of revetments and tunnel deformations. ○Underground Structure Survey using Reflection Method → An effective survey method for deep underground structure and fault investigations. ○Physical Survey on River Embankments → Investigates the soil composition and properties of embankments using existing literature and multiple physical surveys. ○Underground Structure Survey using Microtremor Array → A survey method that utilizes small ground vibrations to understand deep underground structures. ● For more details, please contact us or download the catalog.

Company information
Our company was founded in 1942 as a survey company and has established many survey methods, including elastic wave exploration and magnetic exploration. We have built a track record as a construction consultant related to geological surveys, including physical exploration, soil surveys, magnetic surveys, and environmental surveys, gaining high trust both domestically and internationally. In addition to conducting geological surveys related to construction work, disaster prevention, environment, resources, and academic research, we also manufacture, sell, and rent survey equipment, as well as provide comprehensive consulting related to "geology." We conduct surveys tailored to each site, utilizing the techniques we have developed over the years, including the combination of physical exploration and soil surveys, as well as soil contamination surveys and physical exploration. Please feel free to contact us for more information.
