IACDS Webinar: What GPR can do for concrete sawing and drilling?


The webinar “What GPR can do for concrete cutting sawing and drilling?” will be held by IACDS and given by Mr. David Cist, from GSSI.

For decades Ground Penetrating Radar (GPR) has been saving concrete cutters time, money and lives. In the US especially, large service industries have been built around the speed and accuracy of GPR to protect concrete drillers from making holes in places where they shouldn’t. Sometimes shifting a cut location even a centimeter can help avoid a “very bad day.” Very Bad Days can take the form of a binding or broken blade, hitting a 440V conduit or cutting a Post Tensioning cable. It might prevent a very long day, a very long lawsuit or even a very bad injury.
