Part of: Dredging and Dredged Material Disposal


Three fabric-reinforced test sections 300-, 400-, and 750-ft long were successfully constructed on very soft dredged material deposits within the Craney Island dredged material disposal area (Norfolk District, Norfolk, VA). Subsequently, two dikes each about 4000-ft long were constructed using this innovative construction technique to divide the 2500-acre area into three separate areas for improved dredged material management. Prior attempts of conventional displacement construction techniques to construct these dikes failed. Successful construction of these fabric-reinforced dikes was a key element in the rapid implementation of the dredged material management program. Implementation of this program will provide a cost savings of about 270,000,000 over the next 36 years.
