Utility Tracing:
Generally in conjunction with a Topographical Survey we provide details of underground services using a combination of Cable Avoidance Tools (CAT) and Ground Penetrating Radar (GPR). The position of cables/pipes etc. are marked on the ground then surveyed using either GPS or Total Stations for inclusion with the topographical survey.
GPR (Ground Penentrating Radar) - The radar can either be pushed or towed across the ground, depending on conditions of the surface it can automatically detect depth information including pipes and geophysical features.
CAT & Genny - Three modes Power, Radio & Genny
Power Mode - the CAT picks up signals given off by live cables
Radio Mode - Radio mode locates metallic cables/pipes using signals flowing through the ground until hitting metallic services, which can be detected by the locator.
Genny Mode - this is used to apply a distinctive signal that the CAT can detect, this is particularly useful when trying to detect pipes that don't emit any signals or are untraceable through Power and Radio mode.
