Ground-penetrating radar (GPR) is a high-frequency electromagnetic method commonly applied to a number of engineering and environmental problems. The GPR method is used for very rapid, high resolution mapping of the shallow subsurface to:
- Locate and delineate underground storage tanks (metallic and nonmetallic)
- Locate metallic and nonmetallic pipes and utility cables
- Map rebar in concrete structure
- Map landfill boundaries
- Delineate pits and trenches containing metallic and nonmetallic debris
- Delineate leach fields and industrial cribs
- Delineate previously excavated and back filled areas
- Map shallow groundwater tables
- Map shallow soil stratigraphy
- Map shallow bedrock topography
- Map subsurface voids and cavities
- Characterize archaeological sites
