Abstract

Bitumen and plastic sealing materials, as well as watertight concrete, have been used in construction of underground structures for almost thirty years. The question of which type of sealing material hinges on the degree of tightness required of the structure. This report, prepared for the ITA Working Group on Research, examines various classification systems for determining the degree of required watertightness, and damage likely to result from failure to meet the prescribed standard of tightness. The paper also discusses contractual aspects pertaining to permissible leakage water rates, and to repair work that might be necessary to ensure the required degree of watertightness in a structure. Le bitume et les joints en plastique, ainsi que le béton étanche, sont utilisés dans la construction de structures souterraines depuis prés de trente ans. La question de savoir quel type de matériau utiliser pour le joints dépend du degré d'étanchéité demandé à la structure. Ce rapport, préparé pour le groupe de travail de recherche AITES passe en revue un certain nombre de systèmes de classification qui déterminent le degré d'étanchéité nécessaire ainsi que les dommage qui risquent de se produire si les spécifications d'étanchéité prescrites ne sont pas satisfaites. Ce rapport traite également de certains aspects contractuels concernant les taux de fuite d'eau acceptables, et les réparations pouvant être nécessaires afin d'assurer le degré d'étanchéité requis dans une structure.
