Subsidence damage to domestic buildings
A guide to good technical practice
by Richard Driscoll and Hilary Skinner
New Book
Description

Subsidence is a persistent problem in some parts of the UK: around
35,000 domestic insurance claims (often complex and protracted) are
made each year, which cost up to £550 million. This book provides
authoritative guidance to best practice in the technical and engineering
aspects of subsidence damage to domestic buildings, and covers
investigation, diagnosis, repair, prevention and mitigation of building
cracking and deformation. It reviews current information and provides a
clear, logically structured baseline of technical guidance for investigators.
The authors have drawn on many years of BRE experience of researching
subsidence problems, and on consultancy for difficult cases. Key BRE
publications on soils, site investigation and foundation are included in pdf
format in a CD-ROM accompanying the book.
