See Beneath the Surface With GPR

GPR: your 3D vision into concrete slabs

Do you know the benefits of Ground Penetrating Radar? As one of the newer additions to NDT surveying, Ground Penetrating Radar (GPR) has made significant strides in assisting with the clear evaluation of concrete slabs, as well as conducting analysis of subsurface objects. GPR is highly accurate, cost-effective, and is able to provide comprehensive results that clearly identify hidden objects such as power lines, heating tubes, rebar, and post-tension cables. Russell NDE is proud to integrate GPR surveying into our existing non-destructive testing methods. Learn more about the benefits of ground-penetrating radar as well as partnering with Russell NDE for your concrete slab surveying needs!

How GPR Works

Ground Penetrating Radar is a specialized form of Non-Destructive Testing (NDT) that uses low-level electromagnetic radiation to detect and analyze subsurface structures such as rebar patterns located within concrete slabs, walls and ceilings. GPR operates using transmitting and receiving antennas. In order to record data, the GPR unit will emit a pulse into the concrete slab, and record subsequent echoes from objects beneath the surface. Using this highly refined electromagnetic (radar) pulse, GPR is able to create a detailed map of what lies beneath the surface, making it essential for rebar pattern identification, locating pipes and conduit before digging, detecting voids and concrete homogeneity, and much more. Today, GPR is depended on by thousands of professionals spanning multiple industries like the construction sector, municipal infrastructure, and more.

Main Benefits

As with most non-destructive testing, one of the main benefits of GPR technology is its ability to conduct a thorough analysis without the need to excavate or displace the material in question. GPR, in particular, is remarkably fast and accurate and operates with such a low amount of radiation that the electromagnetic pulse utilized poses no risk to people. Ground-penetrating radar technology can produce real-time data and can see through up to 12” of concrete floor pads. Best of all, GPR is cost-effective and requires minimal labour, has instrumentation that can be easily shipped to site, operates using quiet and self-contained units, and can be used to detect metal and non-metal objects, as well as voids and other internal irregularities.
