✦ Synopsis

Winner of the RIBA Book Award, this important and timely publication brings together contributions from leading stone conservation practitioners. It discusses the philosophical principles on which stone conservation is founded and the need to understand the full history and development of a building before starting work. Other topics covered in this book include consolidation, cleaning, and the replacement of stone; conservation of different stone types, including limestone, sandstone, and marble; problems of dealing with polychrome stone; and finally, issues relating to church monuments and graveyards, taking account of the need for good maintenance and health and safety requirements. The book is illustrated with the authors' own examples of stone conservation in practice. Architects, surveyors and craftsmen involved in the conservation of stone structures will find this both a practical and useful reference work.
