Abstract (en)

[origin: WO9749878A1] The invention refers to a waterproofing membrane for roofing comprising at least one water and moisture impervious first sub-layer of bitumen or like material and a second sub-layer which is applied over the first sub-layer. The second sub-layer is comprised of granules of plastic and/or elastomeric material being bonded to the first sub-layer, wherein the waterproofing membrane by means of said granule layer has an essentially fully maintenance-free and environmentally-friendly non-dusting surface structure like a conventional slate-crush bitumen surface. The granules are preferably ground fractions having a flaky form. The granule length is at most 4 mm and preferably within an interval of 0.15-2 mm. The granules may be comprised of integrated recovered plastic and/or elastomeric materials, for example recovered from rejected automotive tires.
