Geophysical surveys for Faults and Sinkholes

Geophysical surveys for Faults and Sinkholes 

Engineered development and assessment of groundwater conditions demand solid definition of subsurface conditions. GPR’s ability to define geologic strata and detect anomalous geologic structure makes it a regular tool in the engineering geophysicist’s arsenal of methods. In addition, GPR is one the few methods that is directly sensitive to the water content and chemistry. Applications range from route selection for roads, railway and pipelines to karst evaluation.
 

Geotechnical Engineering

GPR’s ability to provide high resolution subsurface geological structure leads to widespread geotechnical uses of GPR. Applications are wide ranging such as determination of bedrock depth, definition of soil stratigraphy, identification of karstic features, and location of buried groundwater channels.

Hydrogeology

GPR’s sensitivity to soil water content and geologic structure make it a natural method for hydrogeology investigations. From delineating water table, to stream and river bed structure, to borehole monitoring of contaminant flow, the spectrum of GPR uses is broad and varied.
