Abstract: A flood barrier wall consisting of a flexible tubular flood chamber, skirts and an air-filled flotation collar. In its unexpanded and deflated mode the device is relegated to a substantially flattened condition which can be folded, rolled up or placed on a spindle for ease of transport and rapid deployment at a flood site. Deployment consists of placing the barrier on the anticipated flood site, weighting and fastening the skirts to the ground and inflating the collar. As rising flood water enters the flood chamber it expands said chamber, resulting in an effective flood barrier.

Abstract: A pumping system that is incorporated into and made part of a flexible air tight bag of the interlocking seal variety. Currently, the practice is to squeeze the storage compartment of the bag to force out as much air as possible and then sealing the bag. The improved method provides a means of pumping out air and other gases after the bag is sealed. This method results in a more complete elimination of air and other gases in the storage compartment of the bag.
