The report deals mainly with methods of waterproofing preformed segmental linings, and outlines the provisions for unlined tunnels and for waterproofing tunnels lined with concrete in-situ. The need (or otherwise) for watertightness is discussed, and recommendations are made, based upon existing evidence, for appropriate standards of permissible leakage, their formal classification, and suitable units of measurements. Factors are considered which may influence the selection of permanent waterproofing elements for a tunnel lining system, and an appreciation is made of construction expedients and temporary works which may be an equally essential part of waterproofing the tunnel. A classified list of waterproofing elements is given with suppliers' names and addresses.(a)
