How We Map the Invisible: Multi-Sensor Detection Technology
No single sensor can detect every utility type in every ground condition.
Our field methodology deploys complementary detection technologies in a coordinated workflow — ensuring maximum detection
rates across metallic and non-metallic, active and abandoned, shallow and deep-buried infrastructure.
Ground Penetrating Radar (GPR)
Non-destructive subsurface imaging using dual-frequency and multi-channel antenna arrays (250 MHz – 800 MHz) to detect both metallic and non-metallic utilities — including PVC pipes, concrete ducts, fiber optic conduits, and abandoned infrastructure invisible to electromagnetic methods. High-speed 3D GPR arrays enable full-coverage scanning of roads and rights-of-way without disrupting traffic flow.
Electromagnetic Induction (EMI)
Precision cable and pipe locating using transmitter-receiver systems that induce and trace electromagnetic signals along conductive utilities. Active and passive mode detection identifies energized power cables, metallic water and gas mains, telecommunications lines, and tracer wires on non-metallic conduits — with depth estimation accuracy of ±10–15%.
Terrestrial & Mobile LiDAR
High-definition scanning of above-ground utility infrastructure — poles, overhead lines, transformers, valve chambers, manholes, hydrants, and junction boxes. Mobile LiDAR captures entire utility corridors at highway speed, extracting pole heights, wire sag measurements, attachment points, and clearance envelopes from classified point clouds.
CCTV Pipe Inspection
Robotic camera inspection of gravity sewers, stormwater drains, and accessible conduits — documenting internal condition, pipe material, diameter, gradient, lateral connections, and structural defects. NASSCO/WRc-standard reporting provides asset condition data critical for rehabilitation planning and remaining life assessment.
