Detecting Underground Duct Banks


Using GPR to Locate Subsurface Utility Duct Banks

Through the use of Ground Penetrating Radar (GPR), you can save your utility company, engineering firm or construction company time and thousands of dollars. This is because GPR can detect the duct bank location as well as can identify the depth of those utility duct banks.

The GPR process involves using radar waves to echo off of subsurface utilities. That information is then delivered in real time to the integrated computer, providing readouts and accurate information on the spot. Our experienced technicians can then mark out the location of all utilities, lines and existing duct banks on the surface of the concrete or ground for your team to use as reference as you work on existing banks or trench new ones.

We can also use GPR to detect duct banks and the types of conduits located inside. This is particularly useful if you are unsure of the full scope of conduits involved in your project. Seeking GPR before you drill into a duct bank to replace conduits is one of the smartest moves you can make for your employee’s safety and your timeline and bottom line.
