Overview
Ground Penetrating Radar (GPR) sends short radar pulses into the ground and records the echoes from buried objects and layers. It finds metal and non-metal pipes, cables, voids and changes in the ground without digging.
We use MALA and GSSI multi-frequency GPR systems with DGPS positioning, so every detected utility is shown at its real location on the map.
What's included
- Choice of antenna frequency for the depth needed
- Grid or line scanning of the area
- DGPS positioning of every scan
- Marking of detected utilities on the ground
- Interpretation by our team

Questions
How deep can GPR see?
It depends on the antenna and the soil. Lower frequencies reach deeper with less detail; higher frequencies give more detail near the surface. Wet clay reduces depth. We choose the antenna for your target.
Can GPR find plastic pipes?
Yes. GPR detects non-metallic pipes as well as metal ones, as long as there is a contrast with the surrounding soil.
Is the survey safe for roads and buildings?
Yes. GPR is non-destructive and needs no digging or drilling.
