• Karst cavities in various sizes
• Cavity located under tunneling section (measuring 4,500m²)
• Two large and uncharted caverns

Detlef Jordan, Robbins Sales Manager Europe, will answer your questions in detail about the breakthrough on Galerie des Janots, boring in Krast conditions, overcoming the hurdles, and lastly, gives you some advice on TBM tunneling for future references.
