France’s recently completed Galerie des Janots was the scene of some unforeseen challenges.\u00a0 During excavation with a Main Beam TBM, crews encountered a stalagmite studded 8,000 cubic meter cavern, and also a 4,500 cubic meter cavity directly under the bore path. In addition to the two large and uncharted caverns, there were also karst cavities of a multitude of sizes found throughout boring. What exactly did the crew do to beat the odds and power through?<\/p>\n

For the answer, be sure to listen in as Detlef Jordan, Robbins Sales Manager Europe, goes into detail about the obstacles, lessons learned, and recommendations for future tunnels in karst conditions.<\/p>\n
