Abstract

La présente invention concerne une membrane bitumineuse d’étanchéité (1) comprenant - une couche bitumineuse (2) et - un surfaçage (3) en contact avec la couche bitumineuse (2), le surfaçage comprenant • une structure fibreuse (4) comprenant un mat non tissé (5) en fibres de verre et/ou en fibres de polyester dont la face inférieure (5b) est en contact avec la couche bitumineuse (2), et • sur la face supérieure (5a) du mat non-tissé (5) qui n’est pas en contact avec la couche bitumineuse (2), un revêtement blanc (7) comprenant de 0,3 à 6 % en poids de particules de TiO2, de 70 à 90 % en poids d’une ou plusieurs charges minérales de couleur blanche, et de 8 à 25 % en poids d’un polymère organique exempt de doubles liaisons carbone-carbone, ces pourcentages étant exprimés en poids sec rapporté au poids sec total du revêtement blanc, caractérisé par le fait que la structure fibreuse (4) du surfaçage (3) comprend en outre des fibres de renforcement (8) et par le fait que la membrane bitumineuse d’étanchéité (1), et notamment la couche bitumineuse (2), est exempte d’autres structures fibreuses.
