Ground Penetrating Radar
Subsurface Utility Detection & Mapping

GSSI 350HS technology for detecting metallic and non-metallic utilities up to 5m depth. Pre-construction surveys and void detection.

What We Deliver

Ground Penetrating Radar (GPR) reveals what's below the surface without excavation. Identify utilities, voids, and subsurface features before breaking ground — essential for safe construction planning.

  • ✓ Underground utility detection and depth estimation
  • ✓ Metallic and non-metallic utility mapping
  • ✓ Pre-construction subsurface investigation
  • ✓ Void and cavity detection
  • ✓ Utility depth profiling up to 5 meters

Key Capabilities

Utility Detection

Identify water lines, sewer pipes, electrical cables, and telecom conduits with high precision. Works on metallic and non-metallic utilities.

Depth Profiling

Precise depth estimation (±0.2m) for all utilities. Continuous profile data along survey lines for route planning.

Void & Cavity Detection

Identify underground voids, cavities, and sinkholes before construction. Safety-critical for urban infrastructure projects.

GPR Profile Reports

Professional hyperbolic analysis and interpretation. Clear radargrams with utility annotations and depth measurements.

GIS Integration

GPR data converted to CAD and GIS layers. Seamless integration with utility network databases and planning systems.

Safe Excavation Support

Pre-excavation surveys reduce damage risk and project delays. Supports utility relocation and construction safety protocols.

Equipment & Performance

GPR System

  • GSSI 350HS Antenna — Primary workhorse, 350 MHz center frequency
