Jet grouting is a highly versatile soil improvement technique which is currently used for many different purposes in civil engineering, for the construction of new facilities as well as for the improvement of existing ones. It provides static support for foundations, underpinning, earth retaining structures, and provisional support for tunneling, as well as waterproofing. The book examines technical issues, design methods, and control procedures for jet grouting treatments. Though primarily suited to professionals and practitioners, the book will also appeal to researchers and graduate students.
