New in this edition:
When finding another location, redesigning a structure, or removing troublesome ground at a project site are not practical options, prevailing ground conditions must be addressed. Improving the ground—modifying its existing physical properties to enable effective, economic, and safe construction—to achieve appropriate engineering performance is an increasingly successful approach. This third edition of Ground Improvement provides a comprehensive overview of the major ground improvement techniques in use worldwide today. Written by recognized experts who bring a wealth of knowledge and experience to bear on their contributions, the chapters are fully updated with recent developments including advancements in equipment and methods since the last edition.
The text provides an overview of the processes and the key geotechnical and design considerations as well as equipment needed for successful execution. The methods described are well illustrated with relevant case histories and include the following approaches:
The introductory chapter touches on the historical development, health and safety, greenhouse gas emissions, and two less common techniques: blasting and the only reversible process, ground freezing. This practical and established guide provides readers with a solid basis for understanding and further study of the most widely used processes for ground improvement. It is particularly relevant for civil and geotechnical engineers as well as contractors involved in piling and ground engineering of any kind. It would also be useful for advanced graduate and postgraduate civil engineering and geotechnical students.

Klaus Kirsch was a main board director of Keller Group plc, responsible for operations in Continental Europe and overseas until his retirement in 2001, and served thereafter as adviser for the Group’s technical development. He has been involved with some fundamental breakthroughs in foundation engineering, notably the introduction of the vibro stone column technology in the United States, and was instrumental in the development of a new generation of depth vibrators. He has authored many papers and a book on vibratory deep compaction.
Alan Bell is a technical consultant to the Keller Group plc. He was managing director of Keller in the United Kingdom until 2009 and has had close involvement in ground improvement techniques and their development at both the national and international level for over 30 years, including the introduction of vibrated concrete columns to the United Kingdom. He has contributed to many technical publications and is a visiting professor at the University of Strathclyde in Glasgow.
"It provides an interesting insight into the solutions to problems adopted outside of Europe and shows how ground improvement is of considerable importance world-wide in civil engineering today."
