Abstract
The system utilizes a bag containing hydrophilic dry material such as powered polymer. The bag is initially light in weight. When the hydrophilic material is exposed to water it absorbs water and expands to inflate the bag. By taking on the weight of the absorbed, the bag of the invention can replace the function of a conventional sand bag. Unlike a conventional sand bag, the bag of the invention has provision for causing the bags before and after inflation to interlock which strengthens the resulting protective wall. Part of the interlocking effect is created by the incorporation of ballast modules at least two corners of the bag which interlock with pockets on diagonal corners of adjacent bags. In addition to ballast modules, the bag may contain seed modules or pockets which release seeds to vegetate and hold soil on slopes.
