Dredged-material filled geotextile tubes: Design and construction
Large tubes filled with dredged material have been utilized in a variety of coastal and inland projects. The tubes, manufatured of high-strength polyester or polypropylene geotextile, are hydraulically filled with a dredge or pump. The geotextile tubes are typically filled with on-site material. Typical applications would include sand dune restoration, dike construction, groin construction, artificial reefs, and simple waste (sludge) containment and dewatering. The tubes are filled in-place and installation is relatively simple and inexpensive. Recently installed geotextile tubes have shown the following apparent deficiencies: Poorly designed and manufactured seams have failed under the pressures of filling. Tubes filled with coarse material have experienced premature settling and consequent uneven top elevaion. Tubes filled with fine material have retained large quantities of water as a result of fine-grained soils 'caking' on the inside of the tube and limiting the ability of dredged liquids to drain efficiently. Concerns over the durability or long-term performance of the geotextile shell have largely been ignored in the interest of demonstrating the filling process.
