x Preface to the Second Edition
think that the society is prepared to pay the price for a clean environment
these considerations remain just an idealistic exercise.
It is nevertheless hoped that this book will help to appreciate not only
the economical and technical advantages of ground improvement by deep
vibratory methods, but also to recognize their ecological advantages.
This book is written for civil and geotechnical engineers and for the contractors who are engaged in foundation and ground engineering. Students
will find this book helpful in their advanced and postgraduate studies.

Initiated by our publisher Taylor & Francis Group and generously
funded by GuD Geotechnik und Dynamik Consult GmbH, Berlin (www.
gudconsult.de) and Keller Group plc, London (www.keller.com) our book
is now freely available as an open access book. We do hope that this
decision will help to further increase knowledge and application of the
deep vibratory methods of ground improvement which ultimately will lead
to reduce cement consumption and by this way avoid unneccessary CO2
emissions.
