Buried Object Survey: Investigation services related to civil engineering and construction work.
It is possible to accurately determine the position and depth of underground structures.
Buried object surveys can accurately determine the location and depth of underground structures. For areas near the surface, magnetic surveys and ground-penetrating radar surveys are conducted, while for objects located deeper underground, investigations are carried out using boreholes. Japan Physical Exploration Co., Ltd. proposes the most suitable methods based on local conditions. 【Survey Targets】 - Steel sheet piles, H-beams, steel pipe piles, cast-in-place piles - Footings, box culverts - Buried pipes - Shield tunnels - Other foundation structures For more details, please contact us or download the catalog.

basic information
【Survey Methods】 [Surface Investigation] ○ Ground Level Horizontal Survey → Conduct horizontal surveys if it is believed that iron materials are buried. ○ Ground Penetrating Radar Survey → Conduct ground penetrating radar surveys to detect voids or objects near the surface. ○ Metal Pipe Detector → Detect the location of iron pipes. [Investigation Using Boreholes] ○ Vertical Magnetic Survey → Conduct vertical magnetic surveys using boreholes. ○ Velocity Profiling → Determine the depth of pile embedment. → Can identify the depth of not only steel and concrete piles but also wooden piles. ○ Borehole Radar Survey → Insert sensors into boreholes excavated near the target objects and detect buried materials from the differences in radar wave reflection images. ● 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.
