Abstract: A water-impermeable and adhering elongated liner protection device for temporarily externally protecting a structure such as a house building or an appliance item or the like against natural disasters such as flood, wind and the like. The liner substantially covers the perimeter of the structure from the ground surface surrounding the structure up to the base, the external side walls, including discontinuities such as corners, doors and window openings, and the roof of the structure. Generally heavy weights such as sand bags are distributed over the liner lapping over the ground surface to provide a hermetic protection between the surface and the liner. The preferably sticky and stretchable liner forms successive layers that wrap around the structure and adhere to the latter while sealably overlapping other the adjacent layer. The present invention also relates to the method of using such protection device.
