Hazardous Material Investigation: Survey Services Related to Civil Engineering and Construction Work
We contribute to preventing disasters by conducting high-precision surveys and assessments without contact.
Hazardous material exploration involves the detection of mines, bombs, shells, and similar objects, utilizing methods such as magnetic surveys and electromagnetic surveys (metal detectors, ground-penetrating radar). The exploration method varies depending on the type of hazardous material and the depth at which it is buried. At Japan Physical Exploration Co., Ltd., we contribute to preventing disasters by accurately investigating and determining the buried location, depth, and magnetic quantity of unexploded ordnance and other hazardous materials, both underwater and on land, using non-contact methods. [Types of Hazardous Materials (Bombs)] - 250 kg bombs, 1 ton bombs - Mines, depth charges - Incendiary bombs, shells, rifle bullets, poison gas shells, etc. For more details, please contact us or download the catalog.

basic information
【Survey Methods】 ○ Vertical Magnetic Survey → Exploration of unexploded ordnance underground using boreholes → Sensors are raised and lowered at a constant speed using a dedicated lift for measurement ○ Land Horizontal Magnetic Survey → Can be used to explore buried or embedded metals in all land areas, allowing for measurement of planar position and depth ○ Exploration using Metal Detectors → More reliably and accurately detects metallic objects such as unexploded ordnance ○ Marine Horizontal Magnetic Survey → Can thoroughly explore wide marine areas for hazardous materials and obstacles using a magnetic inclinometer ○ Underwater Exploration → Conducts final confirmation of magnetic anomaly points identified by magnetic surveys using metal detectors and divers to assess safety ● 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.
