Non-destructive surveys applied to archeological research help identify the existence of underground structures of archeological interest, both quickly and accurately.

TST Engineering utilizes GPR (Ground Probing Radar) to detect buried subsurface elements in respect of archaeological research. This allows field archaeologists:

- to discover and study the possible presence of buried structures;
- to minimize traditional excavations;
- to save time and money;
- to reduce inappropriate excavation in the areas of interest.

The images of buried archaeological remains can be displayed on 3D maps, or simply identified on the project plan.

These maps can be used as a primary guide to plan excavations, or to define sensitive areas containing archaeological remains. In conclusion, these geophysical practices allow large areas of buried remains to be studied efficiently and accurately, while preserving and protecting the environment in question.
