Stream EM

Ground penetrating radar for utility location and mapping

Stream EM

Stream EM is the multi-channel ground penetrating radar solution dedicated to utility locating and mapping.

The solution has been conceived to cover tens of hectares/day, obtaining the best utilities detection quality thanks to 40 separate channels. The solution includes double polarized (VV and HH) antennas to cover wide road surfaces. The system maintains the same maximum data collection speed, 15 Km/h, with only longitudinal scans for both longitudinal and transversal pipes detection.

Stream EM makes possible what was a dream until now. Imagine mapping all the underground utilities in large areas of dozens of hundreds Km2, obtaining clear and easily enterable results. The high number of antennas increase the quality of the data achievable boosting the reliability of pipes detection.

Stream EM is easily dismountable, enabling it to be transported in a van. It can be reconfigured for mapping sidewalks and difficult areas. The systems is also easily adapted, by using suitable kits, for other applications (archaeology, environmental, road/runway).

The systems features:

  • Massive array of 40 antennas in two polarizations: A massive array of 40 antennas ensures a high sampling density. This results in accurate 3D modeling of the subsurface and ease of detecting buried targets and anomalies. The use of both polarisations provides optimal detection of main and junction pipes at the same time.
  • Speed: Stream EM can be towed by a car up to 15 km/h. This boosts productivity as Stream EM can:
    • Survey many miles per day
    • Be operated by only two people
    • Run continuously without interrupting traffic
    • Keeps the crew safe inside the vehicle.
  • Accurate to less than 5 cm: Stream EM can be interfaced with GPS or a total station to accurately geo-locate the surveyed area. All the pipes, cables and anomalies are detected with high accuracy and are individually distinguishable.
  • Professional Subsurface Utility Engineering (SUE) survey: Pipes, cables and buried object can be automatically transferred to CAD and GIS format with a proprietary software tool.

Benefits of Stream EM include:

  • Improved management of underground utility design, relocation and coordination;
  • Cost and time reductions: No need to block traffic or perform surveys at night;
  • Increase in accuracy with a detection accuracy of as little as 5 cm;
  • Increase productivity and have the ability to detect every buried target;
  • Highly modular structure allows it to be reconfigured to map sidewalks and difficult to access areas
