Why Multi-Sensor Utility Detection Matters

Accurate detection of underground services before you excavate.

Municipal and site as-built drawings are frequently outdated or incomplete. Our underground scanning services combine Sensors & Software LMX200 Ground Penetrating Radar with Radiodetection RD8200 electromagnetic locators so neither live power cables nor plastic water lines are missed.

How It Works

Our 4-step underground service detection workflow

Thorough multi-pass utility scanning that gives your civil engineers and site crew total confidence.

Step 01

Visual & Chamber Recon

We inspect manholes, valve boxes, distribution kiosks, and kerb markers to establish known utility tie-ins.

Step 02

EM Passive & Active Tracing

We sweep with Radiodetection RD8200 locators to trace live power signals and induce frequencies onto metallic services.

Step 03

Bi-Directional GPR Grid Scan

We scan with Ground Penetrating Radar to locate non-metallic PVC/HDPE pipes, concrete ducts, and unknown anomalies.

Step 04

Surface Markings & CAD/KML Report

All utilities are marked on site with depths and compiled into a georeferenced PDF, CAD, and KML utility report.

What is included in your underground utility detection service?

Our underground utility detection service includes a comprehensive on-site sweep using both Electromagnetic (EM) cable/pipe locators and Ground Penetrating Radar (GPR), immediate color-coded surface markings with depth estimates, and a formal utility detection report with annotated photos and optional CAD/KML drawings.

Can underground scanning services detect both water pipes and electrical cables in the same visit?

Yes. Because we deploy both GPR and electromagnetic locators on every utility detection callout, we locate water pipes, sewer drains, gas lines, electrical cables, and fibre-optic ducts during a single site visit.

Do you provide utility detection in Johannesburg and Gauteng at short notice?

Yes. Our Gauteng mobile field teams provide 24–48 hour mobilisation across Johannesburg, Sandton, Midrand, Centurion, Pretoria, and the East and West Rand.
