Tunnel inspection, clearance check, thermography, damage assessment

Tunnel inspection is a ongoing standard task for the bodies responsible for tunnel construction work and transport networks: the structures have to be inspected and maintained regularly and the clearance conditions in the network must be determined.

Other tasks arise from new construction work, for example, such as taking measurements before and after alterations. We offer solutions to meet a wide range of requirements. Our tunnel inspection services and tunnel scanner systems cover a very wide field: from damage recognition and crack detection over recognition of moisture and water ingress up to high resolution 3D scan for clearance assessment. For more information, please take a look at the following examples of projects.
