Ground-penetrating radar (GPR) is a reflexive method that uses high-frequency electromagnetic waves to scan the subsurface or an investigated object quickly and continuously in search of reflective elements or horizons. Thanks to its modular structure (enabling a choice of task-specific measuring antennae) and high recording speed, GPR has a broad range of applications.
We possess an extensive collection of antennae, allowing us to locate components to the nearest centimetre, or scan to depths of up to 100 m in permafrost. For over a decade we have been using the GPR method on roads and bridges, in tunnels and buildings (non-destructive testing of structures), as well as for investigative work in the mountains.
