The Stream C is a compact array solution for real-time 3D mapping of underground utilities and features.

Thanks to the systems increased level of accuracy provided by a massive antenna array, the Stream-C can detect pipes and cables in both directions with a single pass of the GPR.

Daily use of the Stream-C is aided by features including electronic ride height adjustment, options to tow manually or with a small vehicle and a motor assisted drive wheel.

The system has been designed to enable the user to cover survey areas quickly, this is achievable because the system is operating with 34 separate channels, enabling the best quality results possible. The solution includes double polarized (VV and HH) antennas, this enables the Stream-C to travel in a single direction but collect the data for both the longitudinal and transversal pipes detection. The system when towed can obtain data up to a maximum speed of 5 Km/h.

It has long been a dream of utility surveyors to map the underground in the footpath and road with minimal traffic management per day, this dream is now achievable with the systems high productivity rate. The high number of antennas increases the quality of the data achievable boosting the reliability of pipe detection.

This product utilises the GRED HD Basic, GRED HD 3D & GRED HD 3D CAD software.


  • Massive array of 34 antennas in two polarizations, this results in accurate 3D reconstruction of the underground utility network created in a single scan.
  • Compact size: The Stream-C small dimensions enable it to survey areas inaccessible to larger array systems whilst maintaining the same degree of accuracy.
  • 3D radar tomography: visualisation of real-time tomography on a GPS or Total Station assisted cartographic background.
  • Professional Subsurface survey results, pipes, cables and buried objects can be automatically transferred to CAD and GIS formats allowing a complete subsurface GIS based digital map to be produced in just a short period of time.
