GPR Surveys
Ground penetrating radar surveys for underground utilities, voids, buried structures, concrete features and subsurface anomalies.
Nationwide South Africa Coverage
HydroTrace provides this service across South Africa for residential, commercial, industrial, municipal and mining infrastructure clients. We support Gauteng, Western Cape, KwaZulu-Natal, Eastern Cape, Free State, Mpumalanga, Limpopo, North West and Northern Cape projects.
Technical Overview
Ground Penetrating Radar uses electromagnetic pulses to detect changes below the surface. HydroTrace uses GPR for non-destructive subsurface investigation in construction, municipal, industrial and mining environments.
HydroTrace applies a structured technical workflow: assessment, diagnostic investigation, preparation, execution, verification and reporting. This gives clients a clear understanding of the asset condition and the correct next step.

Full Technical Process
Survey Objective Definition
The target type, required depth, scan area and expected ground conditions are defined.
Antenna Frequency Selection
Higher frequencies provide shallow detail; lower frequencies penetrate deeper with less resolution.
Grid Scanning
The scan area is surveyed systematically to build consistent radar coverage.
Radargram Interpretation
Reflections and hyperbolas are analysed to identify probable utilities, voids or structures.
Marking & Mapping
Detected features are marked and recorded with estimated depth where practical.
Reporting
HydroTrace provides findings, limitations and recommended verification actions.
