Standard Locating

Standard EMF locating works by inducing an electromagnetic frequency (EMF) on the asset, and then detects this frequency to determine the location and depths of the asset. This is a quick as easy way to identify metal assets, such as power, phone cables and metal pipes. Other assets, like traceable fibre optics, can be located using this by connecting a clamp to a trace wire, and then detecting the frequency from that wire.

Acoustic Pipe Locating

Acoustic pipe locating works by using a sensitive microphone to listen for the flowing water in the pipe, or for pulses if a stopper is used. This can be used to find leaks in pipes, by searching for the loudest part of the pipe.

Ground Penetrating Radar

GPR works by emitting an electromagnetic pulse into the ground, which will bounce from inconsistencies in the ground can be detected by the GPR to pin point the assets location. This method is used to locate non-metal assets like any water or sewer pipes and can be used to find underground tanks.

Concrete Scanning

Concrete scanners will emit electromagnetic pulses to the concrete and then detect the reflected waves. This is used to determine where supports are within the concrete.

Hydrovac Potholing

If a guaranteed location is required, or the asset cannot be found using non-invasive methods, then hydrovac potholing is the best option. This involves using high pressure water and a vacuum to remove earth from around the asset without damaging it. This is advised when excavations will be occurring near the assets or if dangerous assets like high voltage and gas are present.

Using these methods, we can mark out the location of assets onsite, which you can then reference when undertaking works.
