GeoTubes® are made of high strength polyester fabric panels sewn longitudinally to form a nominal thirty foot circumference tube with closed ends sewn flat. Lengths are fabricated as required. Dredge material is pumped into the GeoTube®, then the effluent water "seeps" out of the tube fabric and the dredge materials are contained. They can be used as dredge containment, barriers and in beach & dune
reconstruction. The GeoTubes® can be then covered over with sand and planted with dune grass.
