Discover Subsurface Features with GPR

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.

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.

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.

gravel bars and a bedrock interface.

Locate Potential Sinkhole Areas with GPR

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

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.

Картографирование особенностей подпочвы с помощью георадара

Геологи используют георадар для изучения комплекса подпочвенных проблем, которыми занимается наука стратиграфия. Кроме того, этот прибор с легкостью обнаруживает тонкие слои почвы и косую слоистость.
