Ground Penetrating Radar Lunch & Learn
Thu, Jan 28 2016

Todays lunch & learn with Biswa Pokharel on Ground Penetrating Radar. Thanks to Biswa and Bhate Geosciences for an informative presentation and a great lunch consisting of chicken pasta, green beans, roasted potatoes along with brownies and three types of cookies for dessert. Ground Penetrating Radar (GPR): A geophysical method that uses radar pulses to image the subsurface. This non-destructive method transmits electromagnetic pulses into the subsurface and based on the reflected signals, it detects presence and location of subsurface targets. GPR can be used in varieties of medium including soil, rock, concrete, ice, freshwater etc. It can detect subsurface objects (rebar, post-tensioned cables, underground utilities), changes in material, voids, cracks etc. GPR can be utilized in several different applications including but not limited to Geotechnical, Subsurface Utility Engineering, and Environmental Engineering.
