Plenty of companies own radar equipment. Few turn it into decisions you can defend.
1. Methods you can audit
We don’t ask you to trust a black box. Every technique we use — 2 GHz void-scattering analysis, 400 MHz frequency-spectrum analysis, time-frequency mapping — comes from published, peer-reviewed research and was validated in the FRA’s independent multi-vendor evaluation at the Transportation Technology Center. Your engineers can check our methods against the literature themselves.
2. Calibrated to your ballast, not a generic assumption
Ballast dielectric properties vary by rock type and moisture — granite and limestone differ measurably, and assuming the wrong value distorts every depth in the report. We calibrate against samples of your ballast with sieve analysis, and report against the index your network already uses: Selig FI, AREMA gradations, or your own thresholds. The result plugs into your maintenance standards instead of creating a translation problem.
3. Decision-ready reporting
A radargram is not a deliverable. Our reports state, by chainage: where ballast is clean, where it’s fouling, how thick the clean layer is, where water is trapped, and which sections cross your maintenance thresholds — with GIS mapping and statistical summaries. Your planners can take the report into a budget meeting unedited.
4. Speed without shortcuts
Survey at normal hi-rail speed, three lines in one pass, no excavation, minimal possession. First-pass results within 24 hours. Speed comes from automated processing and a refined pipeline — never from skipping calibration or review.
5. Honest claims
The fastest way to lose a client is to oversell a technology. So we’re direct: GPR measures relative, not absolute, moisture content. Gradational fouling has no knife-edge boundary. Unusual particle shapes can affect scattering response. We design surveys — combining methods and anchoring with ground truth — so these limits are managed, and we tell you when a finding carries uncertainty. Our reports distinguish what we measured from what we infer.
6. International reach, local delivery
Operating across Canada, the USA, Brazil and Australia, we work within your country’s track-access rules, safety regimes and reporting conventions — with one consistent technical standard everywhere.
How we compare
| Trial pits / drilling | Visual inspection | KHEERAN GPR | |
|---|---|---|---|
| Coverage | Isolated points | Surface only | Continuous, full route |
| Subsurface depth info | At sample points | None | Continuous to 1–2 m |
| Track disruption | High | Low | Minimal (hi-rail speed) |
| Repeatability for trending | Poor | Subjective | High — survey-to-survey comparison |
| Fouling at depth | Yes, at points | No | Yes, continuous |
Drilling still matters — as targeted calibration for the radar, which is exactly how we use it.
