Scantec’s Utility Locating service helps engineers, contractors, and project owners precisely identify and mark the position of underground utilities before any excavation begins. By combining Ground Penetrating Radar (GPR) and electromagnetic detection technologies, we deliver clear and reliable data that minimizes risk, prevents costly damages, and ensures safer construction planning.

Our team operates under international SUE and safety standards, ensuring every utility—from power lines and telecom cables to water, gas, and drainage systems—is accurately mapped and documented.

Typical workflow

1. EM locating.

2. Use GPR to fill the gaps

   • Confirm suspected routes

   • Find non-metallic lines

   • Check crossings / depth change areas

3. Mark and map

   • Paint marks + flags on surface

   • Tie into site control (RTK/total station) for an as-built sketch

4. Quality checks

   • Multiple GPR passes (different directions)

   • Compare EM vs GPR where both are available

   Frequency choice

• Lower frequency (e.g., 200–400 MHz): deeper, less detail

• Mid (e.g., 400–900 MHz): good balance for many outdoor locates

• High (e.g., 1–2+ GHz): shallow + high detail (better for concrete scanning than deep utilities)
