INTRODUCTION

Geo-radar (Ground Penetration Radar, GPR) is an excellent tool for non-destructive surveying of the subsoil in a range of depths varying between a few centimetres and thirty metres. Basically, this technique consists of the analysis of reflections of electromagnetic waves that are produced when there are variations in the dielectric constant of the ground.

AITEMIN possesses lengthy experience in the use of this technique, having undertaken a large variety of works, aimed both at services and at investigation, in sectors as diverse as metallurgy and civil work.

WORK LINES

The main applications and lines of investigation developed with the geo-radar are focused on the following fields:

• Geotechnical investigation prior to planning and construction
• Detection and diagnosis of artificial structures
• Environmental Protection
• Special control in mines and public works
• Archaeological and heritage studies
