Abstract: The present invention provides a barrier comprising a plurality of individual barrier units in a linear arrangement and a relatively rigid energy transfer means wherein the energy transfer means comprises at least one continuous member extending along the length of the plurality of individual barrier units that is connected to each individual barrier unit in the plurality, such that when a force is applied to one individual barrier unit in the plurality, the energy transfer means transfers part of the energy associated with the applied force to other individual barrier units in the plurality of individual barrier units. Also provided is the use of such a barrier to resist vehicle ramming attacks, a method of deploying such a barrier and a kit containing the components of such a barrier.

Abstract: 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.

Abstract: 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.
