Ground Penetrating Radar & Cable Detection

Civil excavation, architectural digging, and plant expansions face extreme risk from underground utilities. Striking a water main, high-voltage cable, or fiber optic trunk can halt works, cost millions in fines, and threaten lives. TerraX3D provides advanced Subsurface Utility Engineering (SUE) services to map under-surface conditions before you break ground.

Ground Penetrating Radar (GPR)

We deploy advanced dual-frequency GPR systems to locate both metallic and non-metallic utilities (concrete, PVC, clay, and fiber).

Underground Utility Detection

Precision electromagnetic locators (EML) detect live power cables and metallic pipelines, tracing structural feeds back to coordinates.

Comprehensive SUE Quality Mapping

Our geomatics and utility tracking specialists map subsurface structures according to international SUE standards, classifying features from Quality Levels D to A:

  • Void & Cavity Detection: Identifying sinkholes, concrete voids, and erosion tunnels under roads or runways.
  • Concrete & Rebar Scanning: High-frequency scanning to locate rebar, tension cables, and conduits inside concrete structures.
  • 2D / 3D CAD Deliverables: Mapped utility lines exported directly to your AutoCAD DWG or GIS spatial layouts.

Key Utility Benefits

Excavation Safety

Identify high-voltage power feeds, gas lines, and high-pressure water mains before mechanical excavation begins.

Design Clash Checks

Map existing lines accurately to design new foundations, sewers, or cabling paths around existing paths.

Populate GIS Records

Upgrade municipal maps and site assets with accurate, real-world coordinate measurements.
