Expansive Soils provides the reader with easy and specific access to problems associated with expansive soils, characterisitics and treatment, and evaluation and remediation. Set up with contributions from worlwide expert, this main reference guide is intended for engineers, researchers and senior students working on soil improvement and foundation engineering. This book deals with expansive soil fundamentals, problems and solutions. It contains a total of 34 papers with contributions by 52 experts from 22 countries. It is intended for engineers, researchers and graduates students working on expansive soils, soil improvement and foundation engineering. Expansive soils occur in many parts of the world but particularly in arid and semi-arid regions; the case studies presented are mainly concerned with these areas. It would have been useful to have included case studies related to shrink/swell hazards and damage, particularly on the Atlantic edge of Europe, in order to present more of a worldwide overview rather than being almost exclusively devoted to arid and semi-arid areas.
