ABSTRACT:
A sealing element is provided which is suitable for sealing flat roofs and engineering structures. The sealing element is made of a water-resistant elastomer or plastomer, and comprises a lamelliform structure of substantially circular shape having from four to six waves, inclusively, distributed radially throughout the structure and around the entire circumference of the structure, the amplitudes of which waves increase regularly from the center of the structure towards the circumference. The undulations enable the sealing element to have an effective surface covering more than 360.degree. without straining any region of the element.
