Utility Locating

All Clear uses portable Ground Penetrating Radar (GPR) technology, along with more traditional methods, to offer underground utility location services. Excavation projects require a precise knowledge of any buried cables, conduit, pipes, or wires, as damage to these utilities, the excavation rig, or even the operator may be quite severe if a utility were impacted by excavation. Using modern technology, All Clear can create an effective map of these utilities to make your work site safe for digging.

GPR is especially useful for non-metallic material, such as fiber optics, and allows our crews to systematically scan the property and create a grid of any buried materials. All Clear uses the GSSI UtilityScan 350 HS for it’s GPR services. The equipment uses a midrange frequency which is ideal for locating utilities and underground storage tanks.

It also can identify rebar and mesh in concrete and is ideal for locating metal, but can also locate terracotta and plastic pipes, and Fiberglass USTs (Underground Storage Tanks). More traditional methods, such as metal detectors or surveying /plotting may be used in addition to GPR for extra assurance.

With this combination of methods, All Clear can efficiently plot the paths and outlines of underground utilities and features using GPS, and can also mark them on the ground for excavation crews to avoid. Other underground features that may pose a safety issue for work crews, such as voids or sinkholes, are also detectable with GPR technology.

GPR can also be used to locate specific areas for digging, such as the outlines of geological features or the delineation of contaminated areas. Even the sources of contamination may be located with GPR, allowing you to target your excavation project and limit the amount of time required on-site.
