<p>A barrier comprising a floor, a barrier wall attached to the floor and a chamber operable to receive a fluid and thereby transform a foldable barrier into an operational barrier. The barrier is located by a barrier system which comprises a vehicle on which the barrier is stored in a storable configuration on a reel, carried by the vehicle. The barrier is rolled off the reel, off the back of the vehicle, and anchored before the vehicle is moved forwards to unroll the barrier onto the ground. As the vehicle moves, a fluid is introduced into the barrier to thereby cause the barrier to be arranged into an operational upstanding barrier.</p> |
