RIS Ground Penetrating Radar (GPR) Systems can accurately and nondestructively “see” through solid pavement materials, such as asphalt, concrete and soil to detect subsurface objects and determine the condition and thickness of the material examined. The IRIS is an ideal technology for detection of bridge deck delaminations, voids, subsurface moisture accumulation and the thickness of asphalt pavement layers…All at highway speeds!

Kansas Geological Survey uses Geophysics to Find Border Tunnels
The Kansas Geological Survey has some interesting seismic equipment that they have used on behalf of the U.S. Department of Homeland Security to look for drug tunnels along the US-Mexico border. I’ve never seen anything quite like this. The sensors all appear to be placed within an old fire hose and mounted onto a Bobcat Toolcat utility machine. On the front of the vehicle is a cyllinder with a 60-lb weight that gets dropped. Read on. (Photo by Richard Gwin, LJWorld.com)
