Abstract
A method for waterproofing a substrate including steps of: I) heating a hot melt bitumen membrane composition to provide a molten bitumen composition, II) applying a layer of the molten bitumen composition to a surface of the substrate to form a first bitumen layer, III) covering at least a portion of an upper surface of the first bitumen layer with a prefabricated reinforcement membrane, and IV) applying a layer of the molten bitumen composition to an upper surface of the prefabricated reinforcement membrane to form a second bitumen layer, wherein the prefabricated reinforcement membrane includes a polymer-modified bitumen layer including: a) bitumen B1 and b) at least one first modifying polymer MP1.
