Overview

The growing awareness of the dangers of groundwater contamination has led to a rapid growth of interest in the techniques used to seal boreholes and other underground excavations such as mine shafts and adits. This book presents an overview of the state of the art in borehole sealing by collecting together information from diverse and often not readily accessible sources. The scope of the book ranges from descriptions of practical sealing methods to the results of experimental investigations on seal performance, and includes simple and advanced methods of analyzing, designing and testing borehole seals. Extensive experimental results on both bentonite and cementitious seals are included. This book will be an essential reference for hydrologists, petroleum, environmental and geotechnical engineers, mining companies and consultants and others involved in the sealing of underground openings and the prevention of groundwater contamination. This book should be of interest to environmental engineers, professional petroleum engineers, mining and geological engineers and hydrologists, graduate students in these areas.
