KHEERAN Corporation delivers a complete GPR ballast survey in Brazil for heavy-haul and freight railways. Iron ore corridors carry crushing axle loads through some of the wettest operating conditions in the world. As a result, ballast degrades faster than visual inspection can track. Our hi-rail Ground Penetrating Radar programme measures that degradation continuously — with no digging and minimal possession time.

Why Heavy-Haul Lines Need a GPR Ballast Survey in Brazil

Heavy axle loads grind ballast into fines, while tropical rainfall drives those fines into the drainage path. Consequently, fouled sections hold water, geometry decays and derailment risk climbs. A scheduled GPR ballast survey in Brazil finds these sections early. Moreover, it ranks them, so undercutting and shoulder-cleaning budgets flow to the worst kilometres first.

Multi-Frequency Radar, Calibrated to Your Ballast

KHEERAN combines 2 GHz horn antennas for fouling detection with 400 MHz antennas for deep substructure layering. Fouling classifications are cross-checked against sieve-analysed calibration samples of your own ballast. In addition, GPS positioning and video mapping tie every metre to your chainage, and outputs align with ANTT expectations and international practice.

What the Survey Delivers

  • Fouling categories by chainage — track centre and both shoulders.
  • Clean-ballast thickness profiles for renewal planning.
  • Trapped-water and ballast-pocket flags for drainage works.
  • GIS condition maps with prioritized remediation recommendations.

First-pass results arrive within 24 hours of survey completion. Therefore, planners can act while equipment is still in the corridor.

One Campaign, the Full Substructure Picture

A GPR ballast survey in Brazil pairs naturally with our track geometry measurement and LiDAR programmes — one mobilization, three datasets. Furthermore, our AI-assisted analysis compresses thousands of kilometres of radar data into clear maintenance priorities.
