GPR sees widespread use for locating buried pipes and cables. The unique ability of GPR to detect non-metallic as well as metallic structures provides a distinctive locating capability. GPR can be deployed in simple 'locate and mark' mode for rapid on-site solutions. Whether carrying out Subsurface Utility Engineering (SUE) or controlling excavation in complex areas, GPR 'surveying and mapping' provides unmatched capability for defining subsurface infrastructure.

Locating Pipes & Cables
GPR's ability to respond to both metallic and non-metallic features give it a unique capability for pipe and cable locating. Unlike conventional cable locating devices that need metal pipes and cables to carry electrical current to be detected, GPR detects plastic, asbestos and concrete pipes and structures as well as metallic ones. Further, exploiting the instrument positioning and signal travel time enables estimating target depth. When outfitted with GPS and feature-tagging data loggers, a locating record can be provided as part of the standard locating and marking activity.

Subsurface Utility Mapping
Everyday construction now needs a detailed mapping of buried utilities and support infrastructure. Depth and location are critical in new structure designs. Extensive studies have show that using SUE (Subsurface Utility Engineering) practices leads to cost benefits of 4 to 20 times. Successful SUE requires comprehensive mapping of all buried structures. Engineering design and construction can be planned effectively thereby greatly reducing costly surprises. GPR operating in survey and map mode delivers 3D images of the subsurface. SUE service providers now routinely exploit GPR's ability to detect pipes and cables as well as other structures to deliver the most complete maps possible.
