Around 50% of Europe’s annual construction budget is spent on refurbishment and repair of existing structures. This report is the culmination of a wide-ranging survey into the performance of both current European concrete repair techniques and inspection practice, and current research projects. It assesses case histories gathered from across the sector from owners of concrete structures, repairers and research institutes, and presents its findings using charts, graphs, tables and photographs. A review of the problems of concrete durability, current issues of sustainability, and the differing expectations of what concrete repairs should acheive, provide an insightful introduction to the subject. The survey was conducted by the CONREPNET network, made up of European research and representative bodies sponsored by the European Commission. Paperback, 56 pages.
