UNDERGROUND PIPES/CABLES DETECTION

A single detection tool might be unable to locate all the underground utilities that lies beneath the subsurface. Detecting an underground utility is sometimes accomplished through a single or some combination of various techniques. At GS&C, We offer a full range of private utility locating services to help delineate and identify the depths of buried pipes, cables and possibly other subsurface utilities through the use of different utility locating tools such as ground-penetrating radar (GPR), the electromagnetic pipe/cable locators, metal detectors, acoustic pipe tracers, and more.

Ground Penetrating Radar (GPR)

This equipment sends down electromagnetic waves to the ground often between 10 — 1000MHz and records the reflections from the subsurface materials as a result of the changes in the dielectric properties. This tool helps to detect both metallic and non-metallic utilities.

Electromagnetic Cable Locators

Here, a transmitter emits an electromagnetic wave often between 50Hz to 480 kHz into the ground or directly to the pipe and a receiver detects the reflected waves from the underground utility. This tool is useful for detecting metallic utilities only.

Metal Detector

A transmitter emits an AC magnetic field into the ground and a receiver analyses the resulting or corresponding magnetic field. This tool is useful for detecting metallic objects only.

Acoustic Pipe Tracers

An acoustic transducer sends a sound wave into the pipeline. The emitted sound wave travels along the utility lines and certain special sensors which are on the ground detect the sound waves that reach the surface. This method comes in handy when detecting plastic pipe (Typically water/gas pipe).
