Subsurface Utility

Subsurface Utility Mapping

GPR can be a powerful tool for mapping the location and depth of metallic, non-metallic, plastic, concrete and asbestos-concrete utilities. Mapping with GPR to systematically cover an area can quickly reveal the distribution and character of multiple buried utilities.

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 & Mark’ mode for rapid on-site solutions. Whether carrying out Subsurface Utility Engineering (SUE) or controlling excavation in complex areas, GPR ‘Survey & Map’ mode 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, target depth can be estimated using instrument positioning and signal travel time. 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 shown 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.
