The present invention provides a flood defense barrier comprising a first plurality of individual compartments connected by a first, non-releasable fastening means, wherein the plurality of individual compartments comprises at least one second, releasable, fastening means effective for releasably fastening the first plurality of individual compartments to a second plurality of individual compartments. Also provided is a flood defense barrier comprising a first plurality of individual compartments connected together and provided with a continuous length of water impermeable material extending across the individual compartments along at least one side of the barrier, a second plurality of individual compartments connected together and provided with a continuous length of water impermeable material extending across the individual compartments along at least one side of the barrier, and fastening means for fastening the first plurality of individual compartments to the second plurality of individual compartments, as well as methods of deploying said flood defense barrier and uses thereof.

The present invention relates to a foldable barrier structure comprising a compartment bounded by a pair of opposed side walls and a pair of opposed end walls, at least one pair of opposed side or end walls being formed from a flexible, foldable material incorporating a stiffening element and a means for receiving a hinge member which permits folding of a central region of each opposed side or end wall of the at least one pair of side or end walls. Also provided is a multi-compartmental foldable barrier structure comprising a multiplicity of such compartments connected, affixed or adhered to one another end to end, as well as a flood defense barrier comprising a first multi-compartmental foldable barrier structure provided with a continuous length of water impermeable material extending across the individual structures along at least one side of the barrier; a second multi-compartmental foldable barrier structure provided with a continuous length of water impermeable material extending across the individual structures along at least one side of the barrier; and fastening means for fastening the first multi-compartmental foldable barrier structure to the second multi-compartmental foldable barrier structure.

The invention relates to a transport bag comprising a base, a top portion, and side walls extending between said base and top portion in such a way that a volume for storing granule, fluid, viscous, or semi-fluid materials is formed, wherein the transport bag comprises at least one narrowed portion extending through a middle axis of said side wall from a upper edge to a bottom edge of the side wall.
