Proven Technologies and Industry Expertise
Since 2005, HyGround has been a defining voice in the field of analyzing track geotechnics for substructure maintenance through the application of leading-edge technologies including Ground Penetrating Radar (GPR), Light Detection and Ranging (LiDar), specialized software and partner education.

  • Ground Penetrating Radar (GPR) is the most accurate way to provide substructure depth analysis delivering fouling, moisture, and substructure layer mapping as well as identifying deeper defects such as ballast pockets and shoulder heaves. HyGround GPR penetrates to 10 feet below the ground surface and provides a full-width assessment of the substructure condition from shoulder to shoulder and uses GPS to record precise fault locations. This analysis allows railroads to deploy the necessary resources to mitigate train vehicle bounce and avoid track component wear through the reduction of dynamic track loading. Also, Loram HyGround GPR is not susceptible to problems with normal ambient electromagnetic energy and has been extensively used in urban areas.
  • LiDAR (Light Detection and Ranging) scanning creates accurate 3-dimensional visual ground surface mapping of contours from digital terrain models (DTM). These models used in conjunction with GPR data collection provide key information for track structure analysis and improvement.
  • HyGround Geotechnical Services software is designed specifically for railroad structural surveys, data analysis and maintenance planning. This software helps to process and interpret the data collected during measurement for better analysis and visualization to interpret and analyze multiple datasets on a single screen.
  • Training programs provide track managers with the necessary skills to evaluate track substructure health, determine root causes of premature failures and apply proven restoration practices to get track back up to speed.
