Soil form the basis of life on Earth. It has been rightly said ¿The soil is the great connector of lives, the source and destination of all. It is the healer and restorer and resurrector, by which disease passes into health, age into youth, death into life. Without proper care for it we can have no community, because without proper care for it we can have no life.¿ Elementary Geotechnical Engineering is a comprehensive reference book on the introduction about the soil, its formation and various engineering properties of soil. The details have been discussed which is important for a civil engineer to know whether he/she is in structural, transportation, environmental or any other department related to civil engineering.This book has been designed in such a way that it will cater the needs of both the diploma students as well as the B.Tech/B.E. students to know about the soil mechanics in a manner which is easy to learn and grasp. This book will prove useful for all related to geotechnical engineering and as a whole civil engineering. The style is lucid and simple and includes a large number of illustrations to support the technical details.
