Discover Subsurface Features with GPR

Ground penetrating radar offers an accurate, non-destructive solution to mapping the subsurface of the earth. With GSSI GPR antennas, it is simple to locate features of interest and subsurface layers in real time, up to 100 feet or more.

In addition to GPR solutions, GSSI provides the industry’s most reliable, state-of-the-art EM profiling system for geologists, engineers and scientists worldwide.

Use GPR for Water Table Mapping

Hydrogeologists use GPR to determine the depth to water table and to predict potential pathways for subsurface flow.

Profile collected with a SIR 2 and 100 MHz antenna indicating a well-defined water table interface and stratigraphic cross-bedding.

Collect Bedrock Information with GPR

Geologists and land developers use bedrock depth information for construction planning purposes and identifying pathways for subsurface water flow. GSSI ground penetrating radar systems provide a rapid, cost-effective method for collecting large amounts of bedrock depth information.

100 MHz antenna indicating a well-defined bedrock interface.

Measure Bathymetry with GPR

Bathometric profiling is used by geologists for investigating soft, sub-bottom sediments and underwater targets in freshwater rivers and lakes. Use ground penetrating radar to locate sub-bottom stratigraphy as well as underwater targets, including natural and foreign objects.

Data collected with a SIR 3000 and 200 MHz antenna illustrating shallow sub-bottom stratigraphy, sand and gravel bars and a bedrock interface.

Locate Potential Sinkhole Areas with GPR

Geologists use GPR to locate sinkholes and features related to karst environments.

GPR profile collected in Central Florida with a
SIR 3000 and 200 MHz antenna indicating a very large sinkhole feature, limestone bedrock horizon and the characteristic overlying slumping stratigraphy. Note use of survey wheel for data positioning.

EM is used in environments that have higher ground conductivities, such as clayey soils. The EM data set illustrates the lateral extents of a resistive anomaly common to sinkhole geology. Note use of GPS for data positioning.

Map Subsurface Features with GPR

Geologists employ GPR to examine complex subsurface problems, such as stratigraphy. Additionally, thin layers and cross bedding are easily resolved.
