Underground pipeline detection

Since 2012, French regulations require companies to detect subterranean pipelines before any construction work can begin (the DT/DICT decree, also called the anti-pipeline damage reform).

This allows firms to locate all data about existing class-A subterranean pipelines: lighting, electricity, sanitation, rainwater, telecoms, fibre optic, heating – made of any type of material (PVC, HDPE, STEEL, CAST IRON, etc.)

Our experts detect and georeference subterranean pipelines with our cutting edge equipment (georadar).

Our acoustic and magnetic technology is non-destructive and provides a high-precision of the ground beneath your feet.

In addition to this, a drone ortho-image is captured to help make the most of the information obtained.
