Field-tested solutions: Proven pre-excavation grouting (PEG) methods to limit costly water ingress, balanced to requirements.
Engineer-focused guidance: Clear, practical strategies that bridge targeted results and the required mitigation measures.
Global experience: Lessons and case studies from Scandinavian and international hard rock tunnel projects.
Groundwater can determine the success or failure of a tunneling project. Tunneling Without Water Problems provides engineers with field-tested pre-excavation grouting (PEG) solutions to effectively manage groundwater inflow. Based on decades of international experience, this guide connects theoretical concepts with real-world project documentation. It offers practical insights by explaining why proven strategies work and how to achieve results even in challenging geological conditions. Whether dealing with high-volume, high-pressure water inflow or strict environmental limitations on water ingress, this professional handbook details how to meet specified requirements.
