A method for the waterproofing of joints and/or cracks (11) in the upstream face (10) of dams, other hydraulic works and concrete or masonry structures. A waterproofing membrane (13), comprising a strip of elastically yieldable synthetic material, is fastened to the surface (10) to be protected along the whole joint and/or crack (11), after previous positioning of sliding elements (14, 15) onto the surface (10) to support the membrane (13), and of a protection and sliding substrate (18, 19) properly fastened independently from the waterproofing membrane (13); in this way the waterproofing membrane (13) is allowed to freely elongate and follow the movements of the joint and/or the crack (11) while maintaining a water tightening condition.
L'invention concerne un procédé d'imperméabilisation de joints et/ou fissures (11) dans le parement amont (10) de barrages, d'autres ouvrages hydrauliques et de structures en béton ou en maçonnerie. Une membrane d'étanchéité (13), comprenant une bande d'un matériau élastiquement déformable, est fixée sur la surface (10) à protéger le long du joint et/ou de la fissure (11) dans son ensemble, après positionnement antérieur d'éléments coulissants (14, 15) sur la surface (10), de façon à supporter la membrane (13), ainsi que d'une protection et d'un substrat coulissant (18, 19) correctement fixés de manière indépendante de la membrane d'étanchéité (13). Ainsi, ladite membrane (13) peut s'allonger librement et suivre les mouvements du joint et/ou de la fissure (11) tout en conservant un état d'étanchéité.
