Why use a cable detector with surface penetrating radar technologies?

While we're big fans of hydro excavation at Vac-U-Digga NZ, we appreciate that there are scenarios where GPR services convey lots of advantages.

For example:

  • If you need to detect hidden utilities beneath a concrete surface in Rotorua, we can use a radar cable detector to do so without disturbing the concrete itself
  • In addition to identifying the depth of your hidden utilities, our GPR services will highlight the horizontal elements
  • When it comes to sketching and mapping the location of hidden utilities, no form of technology will provide the same diversity as using a penetrating radar device
  • As you won't need to disrupt substances such as concrete when using our surface penetrating radar, you'll minimise costs in terms of being able to identify mains energy supplies and ensuring your project encounters minimal downtime when it comes to service disruption.

    Cable Detector and Surface Penetrating Radar Services

    Making the invisible - visible

    When it comes to assuring accuracy in detecting underground utilities, few technologies can rival the use of a 3D radar. At Vac-U-Digga NZ, we own and operate the only independent 3D radar for utility detection in New Zealand. Using ground-penetrating radar pulses to image the subsurface of your construction site in areas such as Wellington, Auckland, and surrounding locales, we can detect an array of utilities. The utilities our teams are able to detect include electricity lines, gas pipes, water, and more.


    With our cable detectors, we're able to take a non-destructive approach to identifying where utilities are. Our GPR services are similar to hydro excavation in the sense that they won't cause damage to the areas surrounding the utilities. As a result, you'll know where they are, without having to pay for expensive repairs. Our penetrating radar equipment can tackle difficult areas surrounding Gisbourne, urban projects in Dunedin, and more.
