Natural stone is utilised in monumental works both as a construction material and as a foundation. This volume contains papers and special lectures on monument preservation, reflecting a broad spectrum of issues in three different fields: Architecture, Civil Engineering and Geology. The topics discussed covered the entire process of preservation and included:  

- Processes of rock degradation

- Stone conservation and treatments

- Compatible material for restoration

- Preservation and risk assessment

- In situ and laboratory testing and monitoring

- Rock Mechanics studies and modelling in the context of monuments.

- Foundation problems

- Rock-slope problems at protected sites

- Case histories

The workshop “Preservation of Natural Stone and Rock Weathering”, was held in Madrid in July 2007, within the framework of the 11th International Congress of the ISRM. Consultants, researchers, designers and contractors, as well as a great variety of professionals in many public and private agencies, will benefit from this volume that brings an updated view of the technical problems of the preservation of stone monuments.
