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.
