ABSTRACT:
A bitumen-based waterproofing membrane is provided with an improved edge for sealing with a contiguous membrane to provide a membrane system with improved waterproofing characteristics. A bitumen-based reinforced membrane sheet is coated with granular material to protect the membrane sheet from ultraviolet rays. However, a section of the membrane sheet is first covered with a piece of protective tape which prevents any granular material from being deposited on the lateral section of exposed bitumen beneath the tape. The membrane sheets are then cut immediately prior to the tape or at the edge of the granular coating and then rolled up. Accordingly, the lateral section of bitumen which is covered by the protective tape is on the innermost part of the rolled-up membrane sheet. During installation, the tape is removed and the exposed bitumen or selvage section is disposed below an adjacent or contiguous membrane. Heat is then applied for an easy and effective seal between two adjacent membrane sheets.
