KHEERAN Corporation performs advanced railway ballast investigation in Brazil using multi-frequency Ground Penetrating Radar (GPR). Our non-invasive, hi-rail methodology scans the track centre and both shoulders in a single pass. As a result, Brazilian railway owners see their substructure condition continuously — without excavation.

Railway Ballast Investigation in Brazil: Why It Matters

Brazil moves enormous volumes of iron ore, grain and industrial freight by rail. However, intense tropical rainfall, heavy axle loads and fines contamination degrade ballast quickly. Fouled ballast stops draining, geometry deteriorates and derailment risk rises. Consequently, a structured railway ballast investigation in Brazil gives infrastructure teams the data to intervene early — before small drainage problems become costly renewals.

Multi-Frequency GPR for Tropical Railway Conditions

KHEERAN combines 2 GHz horn antennas for fouling detection with 400 MHz antennas for deep layering, ballast pockets and trapped water. Additionally, GPS positioning and video mapping tie every metre of data to your chainage. Fouling classifications are calibrated against sieve-analysed samples of your own ballast. Therefore, results reflect real Brazilian operating conditions, and reporting aligns with ANTT regulatory expectations.

What Your Railway Ballast Investigation Delivers

Deliverables are decision-ready from day one:

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

First-pass results are available within 24 hours of survey completion. Meanwhile, AI-assisted analysis accelerates classification across thousands of kilometres.
