Ground Penetrating Radar (GPR) is suitable for a variety of site surveys. Its main advantage is that it detects changes in the sub-surface, making it suitable for detecting not just metallic objects, but also most other materials including plastic, asphalt, voids and layer interfaces. Being non-destructive and non-invasive, it can be used in occupied premises with minimal disturbance to the occupants. It is particularly suited for listed and historic buildings, where more intrusive methods are not permitted.
Sandberg have developed Ground Penetrating Radar survey techniques for the Civil Engineering sector, in particular building inspection and investigation. This compliments the range of consultancy, quality management, testing and inspecting services on construction industry materials offered by Sandberg.
