Analysis of existing statutory records (stat plans) and definition of the survey area for optimal site clearance.
Make the invisible visible. Mitigate construction risks and increase productivity with non-destructive Subsurface Utility Engineering (SUE). Before the excavators arrive, we deliver precise results of underground pipes, cables, anomalies and other features.
Why rely on outdated as-built drawings when you can map reality?
Inaccurate statutory utility records are the leading cause of expensive cable strikes and project delays, hence riks for life and limb, commercially and lower productivity. Using Ground Penetrating Radar (GPR), we provide a highly accurate, non-destructive method for scanning the subsurface.
Unlike traditional metal detectors, GPR transmits electromagnetic pulses into the ground and records the reflections. The result? A complete profile of the underground environment.
100% confidence through redundant surveying methods.
A professional subsurface utility survey never relies on a single technology. To validate our GPR data and positively identify active utility networks, we combine our scans with Electromagnetic Locators (EML).
These devices are specifically designed to detect the electromagnetic fields emitted by live cables or induced into metallic pipes, guaranteeing comprehensive site clearance before you dig.
We take full responsibility for data collection. No stress for you—just actionable, high-precision deliverables mapped directly into your GIS or CAD system.

Deployment of high-end GPR systems and EML locators on-site. Georeferencing of all findings via RTK-GNSS (GPS) with cm-level accuracy.
Advanced filtering of radargrams by our geophysical experts to extract even the weakest signals (e.g., deep clay pipes).
Delivery of the final utility mapping as 2D/3D CAD (.dwg), Shapefiles, or BIM models—ready to integrate into your workflow.
Transparent answers to the most common technical questions from civil engineers and project developers.
Our equipment allows us to penetrate up to 6m deep in the soil. Quality of signal for penetration depth depends heavily on soil conditions and the antenna frequency used. In dry, sandy soils, we can reach the best signal. In wet, heavy clay soils radar signal si attenuated, but strong enough to clearly detect many of the underground utilities without big challenges. We always select the optimal antenna (e.g., 400 MHz or 600 MHz) for your specific site conditions.
Yes. Because fiber optics and plastics (PE/PVC) are non-magnetic, classic cable locators fail completely. However, GPR reacts to changes in material density (dielectric constant). This allows us to precisely locate empty conduits, fiber optic trenches, and plastic water mains.
Utility network plans are often outdated, incomplete, or referenced to landmarks (like curbs) that have shifted over the years. Furthermore, private service connections or abandoned lines are rarely documented. An on-site geophysical utility survey is the only way to reduce the risk of utility strikes to near 0%.
