What is GPR: A Brief Description by GSSI. Ground Penetrating Radar (GPR) is a non-destructive geophysical method that uses high-frequency radio waves to image the subsurface. Pioneered by companies like GSSI (Geophysical Survey Systems, Inc.), it works by transmitting a pulse into the ground and recording the reflections from boundaries between different materials (e.g., soil, rock, pipes, voids). GPR is invaluable for a wide range of applications including utility locating, concrete inspection, archaeological investigation, environmental studies, and geological mapping, providing a clear picture of what lies beneath without any digging.

  • Non-destructive testing (NDT) method for imaging underground structures and objects.

  • Uses electromagnetic waves to detect changes in subsurface material properties.

  • Generates cross-sectional profiles (radargrams) of the subsurface.

  • Applications include finding utilities, rebar in concrete, gravesites, and bedrock.

  • Depth and resolution depend on antenna frequency and ground conditions.

  • An essential tool for construction, engineering, forensics, and utility management.
