Abstract (en)
1. Method for rendering waterproof a roller compacted concrete hydraulic structure such as a dam wherein an impermeable membrane (2) is placed on the side of said structure (1) in contact with the water, wherein said membrane (2) is made up from a staggered series of worked and assembled thick plastics material with scales (3) interlocked with each other and then welded together in a continuous way and fixed into the structure (1) by vertical fixings (11, 13) and separated from said structure (1) by a geotextile complex (4), enabling movement of the scales (3) and initiating microfissures spread regularly through the structure (1).
