GPR & Subsurface Investigation
See through concrete and soil with electromagnetic precision. We locate hidden utilities, rebar, and subsurface structures before they impact your project.
The Problem
Undocumented underground utilities and hidden structural elements pose significant risks to safety, schedules, and budgets during excavation and renovation.
Our Solution
We utilize high-frequency Ground Penetrating Radar (GPR) to map subsurface conditions without destructive investigation. Our specialists interpret radar signatures to provide accurate 3D locations of hidden assets, allowing for informed site planning.
Technical Workflow
Site Context Assessment
We review existing utility maps and heritage records to develop a targeted scanning strategy for the site.
High-Frequency Scouting
Our technicians deploy GPR systems to scan the target area, capturing electromagnetic reflections from subsurface anomalies.
Signal Interpretation
We process raw radar data using specialized software to differentiate between utilities, voids, rebar, and geological features.
Spatial Mapping
Identified features are mapped into 3D space, providing depth and orientation data for every detected subsurface asset.
Digital Twin Integration
Findings are integrated with BIM or GIS environments, ensuring subsurface risks are visible to all project stakeholders.
