KHEERAN Corporation delivers precise ballast investigation with GPR across Australia, providing continuous, non-invasive railway substructure assessments for Australian railway networks. Our multi-frequency Ground Penetrating Radar technology maps ballast condition at operational survey speeds. As a result, Australian railway owners receive the full picture of their substructure — without excavation, track damage, or service disruption.
Ballast Investigation with GPR in Australia: The Technology
KHEERAN operates the IDS SafeRail multi-frequency GPR system. Furthermore, our hi-rail vehicles simultaneously deploy two 400 MHz ground-coupled antennas at the track shoulders and one 1 GHz air-coupled antenna above the centreline. Consequently, each survey pass captures both deep substructure profiling and high-resolution ballast fouling detection in a single operation. Additionally, every radar trace is synchronised with GPS, Australian railway chainage, and HD video. Therefore, every metre of surveyed track has full traceability.
Why Australian Railways Need GPR Ballast Investigation
Australia’s railways face demanding conditions. Heavy axle loads from iron ore and coal operations, extreme temperatures, and contamination from mineral fines all accelerate ballast fouling. However, traditional Australian ballast assessment relies on widely spaced trial pits. Moreover, these provide only isolated data points that miss deterioration between test locations. In contrast, KHEERAN’s GPR survey maps every metre continuously — giving your team the complete picture.
Deliverables for Australian Railway Owners
KHEERAN provides continuous fouling maps referenced to Australian railway chainage, clean ballast thickness profiles, Selig Fouling Index classifications, and maintenance priority recommendations. Furthermore, preliminary results are typically available within 24 hours of survey completion. Contact KHEERAN today to discuss your Australian railway ballast investigation project.
Australian Railway Standards for Ballast Investigation with GPR
KHEERAN’s ballast investigation GPR Australia services align with standards and guidance from the Office of the National Rail Safety Regulator (ONRSR) and applicable state rail safety frameworks. Furthermore, ballast condition classification using the Selig Fouling Index provides a consistent, internationally recognised basis for maintenance and renewal decisions across all Australian railway types. Additionally, KHEERAN’s GIS-referenced deliverables are compatible with Australian railway asset management systems. Consequently, railway owners can integrate GPR ballast investigation data directly into their maintenance planning and capital renewal workflows.
