Ground Penetrating Radar (GPR) Surveys | Sandberg

Borehole Ground Penetrating Radar (BH GPR) This method applies all the same principles of GPR but uses a modified GPR antenna designed specifically to work in large- or small-diameter borings. The systems must be used in either uncased borings or PVC-cased drill holes, as the instrument cannot transmit a signal through steel casing.

GPR Surveys. Ground penetrating radar (GPR) is a non-intrusive geophysical method used to locate and map sub-surface features. Common applications are in the identification of utilities, concrete thickness, rebar, concrete structural analysis, and void determination.

USGS OGW, BG: Geophysical Methods

Ground Penetrating Radar Survey. Radiodetection techniques are unable to detect non-metallic buried services such as plastic water and gas pipes, fibre-optics and drainage pipes that we cannot introduce a sonde into. To overcome this potentially hazardous situation, we combine the use of Radiodetection with Ground Penetrating Radar (GPR).
