Abstract: A waterproof covering is manufactured by depositing a fluid product, forming an adhering and watertight film, on the surface of the basis or support to be waterproofed. A textile layer is laid on the film before its complete formation, i.e., while a portion of the film forming fluid is still in its fluid state, in such a way that the central portion of this layer is not impregnated and a second fluid forming an elastic waterproof film is laid on the textile in such a way that the central portion of the textile layer is not impregnated. The roll of material used in this process is also disclosed as well as is thewaterproof covering obtained by this process and its use to waterproof terraces, front walls, foundation walls, tanks or the like.
