KHEERAN Corporation delivers professional railway ballast investigation in Australia using multi-frequency Ground Penetrating Radar (GPR). Our hi-rail survey platforms capture the track centre and both shoulders in a single pass. Consequently, Australian railway owners receive a continuous substructure profile with minimal track possession.

Railway Ballast Investigation in Australia: Why It Matters

Australian railways span extremes — from the world’s heaviest iron ore axle loads in the Pilbara to busy metropolitan passenger networks. Extreme heat, flash flooding and long remote corridors make substructure condition hard to track. As a result, fouling and drainage problems often surface only after geometry fails. A planned railway ballast investigation in Australia reveals these issues early, kilometre by kilometre.

Multi-Frequency GPR Built for Long, Remote Corridors

KHEERAN pairs 2 GHz horn antennas for fouling detection with 400 MHz antennas for deep substructure layering. GPS positioning and video mapping reference every metre to your chainage. Furthermore, fouling classifications are calibrated against sieve-analysed samples of your own ballast. Our reporting also supports safety obligations under the Office of the National Rail Safety Regulator framework.

What Your Railway Ballast Investigation Delivers

Each survey produces clear, prioritized outputs:

  • Fouling categories from clean to highly fouled, by chainage.
  • Clean-ballast thickness for the centre and both shoulders.
  • Trapped-water and ballast-pocket flags for drainage works.
  • GIS condition mapping and remediation priorities.

First-pass results arrive within 24 hours of survey completion. Therefore, planners can respond while crews are still in the corridor.
