Geotextile Tubes

Dewatering Applications

GSI fabricates GEOSTRUX™  geotextile tubes used in a wide variety of projects where dewatering of sediments and industrial wastes is required.  GEOSTRUX™ geotextile tubes are fabricated to exacting tolerances that allow them to be used for dewatering of contaminated sediments, fly ash, copper tailings and at numerous marinas, lakes and rivers. The effectiveness of the geotextile tube dewatering is underscored by the fact that often the effluent is clean enough to be returned to the source. GEOSTRUX™ geotextile tubes can be fabricated to custom sizes to facilitate placement specific to the project.

Often the sediment is treated with a polymer before entering the  GEOSTRUX™ Geotextile Tubes that will accelerate the dewatering process. As the sediment enters the geotextile tubes, the sediments particles will flocculate increasing the size of the particle.  The result of this chemical action is that the geotextile tubes dewater more rapidly and the discharged water has dramatically less solids.

Using GEOSTRUX™ geotextile tubes is a cost effective and ecologically friendly process when compared to other dewatering methods.



Coastal and Wetland Structures

GSI GEOSTRUX™ geotextile tubes are also used as a cost-effective alternative to mitigate erosion on coastal shorelines, riverbanks, and lakes using readily available materials for infill. GEOSTRUX™ geotextile tubes filled with dredged materials or sand and strategically placed will dissipate the wave energy, as well as provide structural support against other erosive forces.


Geotextile tubes can be set in place along shorelines and river fronts either to be left exposed to battle the elements, or incorporated into the environment as part of a man-made dune or riverbank. They can also be placed in the water to serve as jetties and groins.

The geo-solutions providers at GSI will coordinate the project activity to utilize the appropriate resources, as well as respond to the most demanding challenges.
