THE WATERPROOFNESS OF STRUCTURAL DIAPHRAGM WALLS

The paper describes the changes in attitude since the 1960s towards the degree of waterproofness that can be expected from diaphragm wall enclosures within waterbearing ground. The early optimism of specialist designer/contractors, that presumed leakages would be minor and could be treated after their occurrence, has been replaced by a realism that requires designers and contractors to adopt preventative measures against leakage. The introduction of waterproof design standards for basement construction related to occupational use, and the subsequent widespread tendency of designers to include internal lining walls with diaphragm wall schemes are described. The location of potential leakages, their cause and prevention are reviewed and the various factors involved in design and construction which affect diaphragm wall waterproofness are summarized. Current methods of specifying criteria for diaphragm wall acceptance are provided and examples from the United Kingdom, the United States of America and France are given. Recommendations are made for specifying acceptance standards of waterproofness for diaphragm walls and a proposed performance specification incorporating these is offered for discussion. (A)
