Geotechnical & Substructure Maintenance

Inspection Services

Diagnose and Solve Problems

Actionable Intelligence is confidence in knowing the condition of your entire track structure to make informed decisions that optimize maintenance programs and investment. Loram Technologies Geotechnical Services diagnose and solve problems that affect the condition and performance of railway tracks by seamlessly combining expertise in track roadbed materials, maintenance techniques and data analytics –resulting in an advanced diagnostic profile of the health of your track today and identifying trends over time for proactive future substructure maintenance program planning.

Geotechnical Service Expertise

  • GPR data collection, calibration, processing, modeling, display, interpretation, automation and QA/QC
  • Track drainage analysis and methods of improvement
  • Track and roadbed safety inspection and maintenance operations
  • Analysis techniques for interpretation of track geometry data for maintenance planning and condition assessment
  • Extraction, manipulation, interpretation and application services for spatial data, in particular, LiDAR (light detection and ranging) data, for ground surface mapping and asset location
  • Conventional and innovative methods for track substructure maintenance and remediation
  • Field investigation studies, site reconnaissance, GPR, video surveying, possible cross-trenches and dynamic cone penetration tests to understand the factors that affect track performance
  • Digital data storage, retrieval, manipulation, display and visualization of large and diverse data volumes
  • Railway track roadbed materials including ballast, subballast and subgrade
  • Geotechnical investigations and analyses related to:
    • Shallow and deep foundations
    • Permanent and temporary retaining structures – soil and rock slopes
    • Ground stabilization
    • Field supervision/inspection

LORAM Geotechnical Services


Ground Penetrating Radar (GPR) provides substructure depth analysis delivering fouling, moisture, and substructure layer mapping at depths up to 10 feet.


Light Detection and Ranging (LiDAR) scanning creates accurate 3-dimensional visual ground surface mapping of contours that combines with GPR data for structure analysis.


Automate the identification of localized ballast deficiencies with LiDAR-based analysis of existing ballast profiles.
