This guide explains why properties founded on clay soils suffer from cracking and provides practical, step-by-step advice and guidance to the home owner on what action, if any, should be taken when confronted by subsidence. It answers key questions, such as how to reduce the risk of damage or prevent existing damage from worsening.
Providing practical guidance for homeowners whose properties have been affected by subsidence, or heave, or who are concerned by the potential risk of damage, this second edition has been expanded to include sections on other types of subsidence and causes of damage that are unrelated to foundation movement.
For 10 years Jeff Howell has been answering readers' queries about property through his very popular 'Ask Jeff' column in the Sunday Telegraph. This book, in user-friendly Question and Answer format, addresses all the issues every home owner needs to know. Packed with expert tips, Jeff Howell offers comprehensive and authoritative advice on everything from boilers and builders, to central heating, condensation, damp proofing, dry rot, plumbing and woodworm. Using readers' stories as case histories, this authoritative book is the key to understanding how to maintain your home properly. How do you decide what needs doing and when? How do you find a decent builder? How do you judge if the work has been done to the right standard? All the answers and more are here in this clearly presented, accessible and practical book.

The first edition dealt specifically with the problems associated with properties founded on shrinkable clay soils, and was reprinted many times. The second edition has been expanded to include sections on other types of subsidence and causes of damage that are unrelated to foundation movement.
This book provides a practical strategy for obtaining a more complete and accurate geologic site characterization. The strategy and methods to characterize complex geologic settings are readily available. The strategy utilizes readily available technology, basic science and good, old-fashioned common sense resulting in a solid understanding of geologic and even karst or pseudokarst conditions. We provide an introduction to many off-the-shelf methods available for site characterization as well as examples of their application throughout the book. The purpose of a geologic site characterization is to understand the 3-dimensional geologic framework, along with the engineering and hydrologic properties of a site including any man-made impacts. A well-done site characterization is the cornerstone of all geotechnical, groundwater and environmental projects. The geologic conditions, particularly karst conditions, can significantly impact a site including its structural stability, groundwater pathways and potential for rapid transport or traps for contaminants. Once we have adequately characterized the geologic conditions can we carry our remediation, design and construction, model flow, and make risk assessments that are accurate and reliable.
Residential Property Appraisal is a handbook not only for students studying surverying but also for surveyors and others involved in the appraisal of residential property for lending purposes. It focuses on the distinct professional competencies required by Mortgage Valuations and Home Buyers Surveys and Valuations, identifying and advising the reader on the extent and limitations of their activities. Generously illustrated, supported by real-life case studies and drawing on the latest research, professional and legal developments.
The ability to predict the potential damage to buildings accurately and to have confidence in the chosen protective measures is of increasing importance for the viability of urban tunnelling. The Jubilee Line Extension Project (JLEP) presented a unique opportunity to capture reliable field measurements of the effects of tunnelling on a wide range of buildings. Building response to tunnelling: Case studies from the Jubilee Line Extension, London is the result of this work. Volume 1 describes the relevant part of the JLEP, the methods of settlement prediction and building damage assessment used on the project, and the objectives of the research. Further chapters provide accounts of the geology and historical development of more of the case study buildings (between Green Park and Canada Water stations of the JLE route). Full transcriptions are included of the before-the-event and independent best practice predictions of surface and at-depth ground movements at two greenfield sites and the settlement of four buildings, which were made specially for the research. The concluding chapter of Volume 1, written by Professor John Burland, presents the overall findings of the research to date. Volume 2 presents, in their geographical sequence, the twenty-seven case studies; from Green Park in the west to London Bridge, and then eastward to Canada Water station. These case studies include two instrumented greenfield sites and several examples of prestigious buildings in London's west end that were protected by compensation grouting. The case studies present descriptions of the buildings, the works that affected them and measurements made to record their response. This valuable and informative two volume book has been written by the experts who participated in the research and is generously illustrated with numerous line drawings, graphs, pictures and maps. Building response to tunnelling: Case studies from the jubilee Line Extension, London will be essential reading to tunnelling and geotechnical engineers and all those who have an interest in this successful and interesting underground project.
