Technical Geology refers to the applications of geology in the study, construction, and operation of technical projects and the resolution of environmental problems.

This book is the first of the two volumes in the series Technical Geology and Geology of Technical Works, and comprehensively covers all topics related to the physical and mechanical behavior of soil and rock formations. It initially analyzes the fundamental theoretical principles that define the specific physical and mechanical properties of soils and rocks, and then describes the sampling techniques as well as the methodologies of laboratory and on-site investigation, as internationally specified in the context of geotechnical studies for the requirements of various technical projects.

The following chapters are included:

- Physical and mechanical characteristics of soil formations
- Physical and mechanical characteristics of rock materials
- Engineering description of rock formations discontinuities
- Geotechnical drilling for engineering investigations
- Laboratory tests of soil formations
- Laboratory tests of rock formations
- On-site geotechnical tests

The above chapters also include:

- Complete Greek and foreign bibliography
- Characteristic application examples
- 40 printed diagrams and laboratory test charts
- 162 figures, 93 tables, and 82 photographs.

This is a modern scientific book that its owner will constantly use as it contains all the relevant information in a concise and user-friendly format. Special emphasis is placed on the experience and knowledge gained in recent years regarding the complex structure and unique technical-geological behavior of geological formations in the Greek territory.
The book is addressed to all those interested in or indirectly related to the subject of Technical Geology, including undergraduate and postgraduate students of all related fields as well as professional geologists, engineers, etc.
