Abstract

The invention is directed to a sealing device (1) comprising a waterproofing layer (2) and a layer of non-woven fabric (3) and having at least one heat-weldable short edge obtained by subjecting at least one of the short edge portions (4, 5) of the layer of non-woven fabric (3) to a heat-treatment. The invention is also directed to a method for producing a sealing device having at least one heat-weldable short edge, to a method for covering a substrate using the sealing devices of the present invention, and to a waterproofed structure.
