Ground Pentrating Radar (GPR)

Powerful, Non-Invasive Technology

Recognized as one of the most powerful remote sensing instruments available today, ground penetrating radar (GPR) is a safe, non-invasive geophysical investigation method for “looking” underground to image subsurface features.

GPR detects metallic and non-metallic, natural and man-made underground features, including: utilities, storage tanks, rebar, sinkholes, voids, water tables, buried artifacts, land mines and graves.

Operating GPR equipment and interpreting results requires in-depth training and field experience.
Our GPR operations are run by geophysicists with extensive academic and field geophysical training.

A Real-Time Look Underground

GPR works by emitting a series of FCC-approved high-frequency, high-amplitude
electromagnetic pulses (radio waves) that reflect off of underground irregularities.
The resulting digital GPR data is fed into a portable video display which provides
a real-time “picture” of a slice of the subsurface area. TBE’s experienced GPR
operators use this picture to pinpoint the precise location of subsurface features
on the ground surface in real time.

TBE owns and operates a nationwide fleet of state-of-the-art GPR systems,
which can be applied to a broad range of engineering and environmental
applications, including:
dot  Subsurface Utility Engineering (SUE)
dot  Utility Locating and Mapping
dot  Condition Assessment of Various Diameter Utilities/Drainage Features
dot  Subsurface Assessments/Encroachments
dot  Concrete Assessments (rebar spacing, thickness, voids)
dot  Examination of Structural Integrity
dot  Landfill Boundary Delineation
dot  Bedrock Surface Profiling
dot  Groundwater Table Mapping
dot  Conductive Contaminant Plume Mapping
dot  Shallow Foundation/Footer Locating
dot  Sand and Gravel Deposit Profiling
dot  Archaeological Investigations
