Why this investigation mattered
The main technical challenge was depth. A request to investigate to approximately 6 m cannot be treated as a guaranteed GPR specification because penetration changes with soil conductivity, moisture, salinity, antenna frequency and target contrast.
The project therefore required a depth-aware interpretation approach: deeper responses had to be judged more conservatively than shallow, high-amplitude features, and the final reporting needed to separate the requested investigation objective from the actual confidence achievable in the field.
Investigation strategy
Systematic area coverage was used across the 3,000 m² site so that deeper responses could be evaluated for continuity instead of being accepted from isolated reflections. Processing was selected to preserve meaningful subsurface structure while reducing background noise.
Interpretation emphasized geometry, lateral continuity and realistic depth confidence. The output was prepared for engineering use with explicit limitations, rather than presenting a uniform detection depth across the entire site.
