Radiodetection

Radiodetection is a method of locating pipes by inducing a radio signal into the subject pipe. This is done by either directly contacting the pipe with a transmitter or by an indirect induction method via a broadcast coil mounted on the surface. Once the signal is induced into the pipe, we are then able to map the pipe's path with a hand-held receiving antenna on the surface.

This is a quick and efficient way to locate metal pipes hidden underground or in walls.

For non-metal pipes we place a small radio-transmitting probe into the pipe and follow along topside with the receiver as the probe is pulled, pushed or flushed down the pipeline.

Ground-Penetrating Radar

Ground-penetrating radar (GPR) will locate pipes below the surface, under reinforced concrete, through reinforced concrete walls and under asphalt and sidewalks. GPR works in a fast and reliable manner. It is also very safe as it uses no radiation.
