Every surveyor carrying out inspections must know something about subsidence, but why does subsidence occur? And there are other factors that threaten the stability of the property, such as tunnels, cliff retreat, flooding or landslip risk? Are engineering reports incomprehensible? With professional indemnity premiums at the current high levels, can the surveyor afford not to be fully informed? This book, written by Gareth Evans, practising surveyor who is also a geologist, provides a convenient and readable overview of the wide range of geological and other natural environmental risks that can affect property, starting with a concise introduction to the science. For those who already have the local geological map to hand, inaccuracy and interpretation problems are discussed. Further reading and resources are listed and there is a detailed glossary, with strong emphasis on mining terms. The text is supported by numerous photographs and useful diagrams.
