Abstract
A flood water containment bag constructed of lightweight, inexpensive porous material with a quantity of water absorbent material therein which increases substantially in volume and weight when it absorbs water entering into the interior of the bag. The bag can be easily and quickly transported to a point of use and arranged in a plurality of superimposed courses when in a flattened lightweight condition and will expand to form a water barrier or wall. Fastener strips are attached to top and bottom surfaces of the horizontally arranged bags to enable them to be interconnected to stabilize the formed barrier.
