Sensors & Software manufactures ground and concrete penetrating radars that help in non-destructive utility detection. 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 a 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 the unmatched capability for defining subsurface infrastructure.
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.
Everyday construction now needs a detailed mapping of underground or 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.
Traditional electromagnetic induction utility locating equipment require utilities to be conductive. They are ineffective for locating plastic conduits or concrete storm and sanitary sewers. Because GPR can detect variations in dielectric properties in the subsurface, it is highly effective for locating non-conductive utilities.
Our GPR systems are designed to overcome challenges such as utility congestion, rebar, and difficult spaces.
