This chapter gives the reader an overview of rocks, rock properties, and rock engineering. It begins with a brief discussion on rock groups, and identification of rocks. Usually rock mass is much weaker than rock substance. Rocks usually exhibit a network of discontinuities such as fissures and cracks, that significantly affect the mass behavior. The chapter briefly explains rock index properties and rock engineering properties. In 1989, Bieniawski proposed the rock mass rating (RMR) by combining several indicators of rock mass features. Some common rock engineering problems include allowable pressures for foundations, ultimate side shear and ultimate point pressure for bored piles. In areas of the Earth where the mean annual temperature of the air does not get above 0º Celsius, the soil may be permanently frozen down to a certain depth; since permafrost is rich in ice, its properties are very much tied to the properties of the ice.
