Geotextile tube



A geotextile tube is a large, tube-shaped bag made of porous, weather-resistant geotextile and filled with a sand slurry, to form an artificial coastal structure such as a breakwaters, dune or levee. Geotextile tubes are a component of the living shorelines approach to coastal management. They are aligned with the shoreline to weaken wave energy and protect against coastal erosion. The tubes facilitate oyster reef development and create areas to dispose of new dredge material. Geotextile tubes are also installed for land reclamation and temporarily installed during the dewatering phase of a dredging operation.

If a geotextile tube is exposed to the elements, it can be vulnerable to bursting.
