Title: “Rock Mass Improvement Techniques — Grouting through the Perspective of the Engineering Geologist”
Duration: Full-day (8:30 AM – 4:30 PM, 26 November 2025)
Convener: Mr. Renos Christakis
Coordinator: Mr. Sanjib Sapkota
Overview: This pre-conference workshop focuses on advanced grouting techniques for rock mass improvement, viewed through the essential lens of engineering geology. It explores the entire grouting lifecycle—from conceptualization and design to execution and verification—emphasizing the critical role of engineering geologists in each phase.
Workshop Objectives: To empower engineering geologists, practitioners, and designers with the knowledge and tools needed to implement robust, adaptive, and site-specific grouting solutions—transforming theory into impactful field practice.
Key Themes Covered:
Grouting Fundamentals: Understanding the why, where, what, how, and when of grouting in surface and underground engineering projects.
Holistic Grouting Design: Integration of geological data, borehole tests, in-situ and lab testing, and groundwater conditions to develop tailored, project-specific grouting strategies.
Grouting Execution: Techniques and practices for permeation, consolidation, void filling, and barrier formation, alongside the control of pressure, volume, and real-time monitoring.
Human and Technical Dimensions: Roles of geologists, debate on best practices (“grouting schools”), equipment selection, and the importance of uncertainty management.
Case Studies Include:
Upper Tamakoshi & Tanahu Hydropower Projects, Nepal – High-pressure grouting and foundation consolidation in complex Himalayan geology.
HATS-2A, Hong Kong – Pre-excavation grouting for deep shafts and underwater tunnels.
Engurhi Hydropower, Georgia – Post-excavation hybrid grouting in a karstified massif for tunnel rehabilitation.
