A pressure-sensitive waterproofing membrane which exhibits good adhesion and flow resistance when applied to a substrate, such as a roof top. Good flow resistance is derived from vulcanization of the pressure-sensitive waterproofing composition after it is applied to the roof top and allowed to cure under the effect of ambient sunlight energy. An exemplary method of the invention for making the field vulcanizing waterproofing membrane comprises the steps of providing a first component that comprises a bitumen and a vulcanizable elastomer, providing a second component that comprises a vulcanizing agent operative to vulcanize the elastomer when mixed therewith, providing an in-line mixer operative to mix the first and second components together without substantially vulcanizing them, and extruding the mixed components through a sheet die to form a layer of vulcanizable waterproofing composition that is capable of having substantially uniform thickness and of being self-adherent to a rooftop surface. |
