  • Patent number: 4824285
    Abstract: An apparatus and method for enviornmentally benign beach reclamation comprising the placing of a synthetic gas permeable mat over the area to be reclaimed and covering the mat with a sand or gravel aggregate supplied from a remote source in the form of a slurry. The liquid for the slurry comprises the water from the body of water adjacent to the beach. All heavy equipment for the beach reclamation is placed at a remote location far removed from the lake bottom, beach and upland area to be reclaimed. Only the manually portable materials and apparatus need to be transported to the beach area, thereby virtually eliminating heavy equipment damage to the upland areas adjoining the beach. The apparatus includes slurry mixing equipment and a slurry pump all mounted on a compact trailer towable with a small truck. As a part of the apparatus are small pumps, manually portable to the body of water, and light-weight plastic hoses and plastic pipe.
