A covering membrane sheet (10), which is adapted to be joined to at least one other covering membrane sheet (20) for covering a surface, comprises a sheet of elastomeric material and, attached to an edge area (30) of the sheet of elastomeric material, a strip (50) of thermoplastic film of a material being adhesively compatible with said elastomeric material. The strip (50) of thermoplastic film is incorporated into the sheet of elastomeric material so that the outward surfaces of said strip (50) are substantially flushed with the corresponding outward surfaces of said sheet. In a method of manufacturing a covering membrane sheet (10) a strip (50) of thermoplastic film is incorporated into a sheet of elastomeric material so that the outward surfaces of said strip are substantially flushed with the corresponding outward surfaces of said sheet. |
