Intervention railroad tunnel French Alps


ABO-ERG, the French daughter of ABO-Group, has expanded in her home country to the reference in complex geotechnical missions. Underneath you’ll find a video regarding a recent intervention in the French Alps (Encombrouze) after a railroad tunnel showing multiple cracks. These cracks were caused by movement of the surrounding rock formation. ABO-ERG is responsible for the drillings and measurements, resulting in a solution to prevent further damage. Because of the difficult terrain of the tunnel, the geotechnical equipment is transported by a Super Puma helicopter. ABO-ERG will be involved in this project for about month.
