Description: The uses of grouting in geotechnical engineering range from infilling voids to compensating for volume loss in tunnelling. The aim of this book is to improve understanding of grouting techniques and thereby to encourage its proper use. The first section of this title looks at the main grouting techniques and explains the principles behind them. It explores concepts such as groutability, the classification and chemistry of grouts, and grouting plant and equipment. The six main techniques - permeation, rock grouting, hydrofracture, ground compaction, jet grouting and compensation grouting - are then examined in more detail, illustrated throughout with case studies. For each, the principles and applications of the technique are described, the plant and equipment detailed, typical injection-hole layouts provided, and information given on monitoring and site operational requirements. The book also covers typical contractual relationships between the various parties in a grouting contract, and sets out their responsibilities. It concludes with a number of recommendations for improving grouting practice. This book will help all those involved in the procurement and use of grouting in ground engineering, including geotechnical and civil engineers, contractors, consultants and clients.
