Elongated cloth bags or tubes made out of plastic material that are filled with sand that can be stacked or arranged to form a seawall-like structure. Other factors being equal, geotubes do not differ substantially from concrete, steel, or stone structures in their impact on the beaches. When they are covered with sand and used for dune restoration, the sand covering is often quickly removed by wind or waves and the bags may be exposed after the first significant storm.
