Abstract
A membrane for waterproofing a building component, e.g., a roof or a basement wall. The membrane includes a first layer of asphalt-elastomer blend which preferably is self-adherent to the building component and an overlying layer of plastic film which bears at least one adhesive strip adhered to the plastic film. The membrane is in the form of elongated strips which are overlapped to cover the building component, and the adhesive of each strip ensures a waterproof joint between the laminae of the overlapped strips.
