Cable Detection


 Ground Penetrating Radar (GPR) is a type of equipment that is capable of detecting underground features such as, Utilities, pipes, geography of subsurface, cavities, voids, and more.

Our GPR capability includes the ability to scan up to 120m underground, locate voids and cavities, scan water features and aerial drone flight, allowing us to  manoeuvre across sloping and potentially inaccessible terrain.

With a wide range of GPR experience, the latest GPR technologies, and a range of GPR frequency antennas, Cambrian is your best and only choice for GPR scanning.
