ABSTRACT:
The present invention is directed to a method of installing an erosion-preventing lightweight, semi-permeable, semi-flexible structure in the form of a dike for erosion control of a bank along a body of water. The method comprises the excavation of hydraulically placed silty or clay-containing sand fill or existing silty or clay-containing beach sands to form a trench and the placing of a synthetic woven fabric at the base of the excavation. A mixture of shell, sand and cement is then formed and placed in the excavated trench and compacted therein in layers to construct a dike. After covering the dike with a porous synthetic fabric, rock-filled gabions are then placed on the water-side face and crest of the dike.
