Dewatering of Sediments & Industrial Wastes

GSI manufactures GEOSTRUX™ Geotextile Tubes for use in a wide variety of projects where dewatering of sediments and industrial wastes is required. These applications include coal ash ponds, industrial sludge and sediments, mining tailings, wastewater treatment plant sludge, organic and inorganic materials, and silts and sands. We also support environmental construction efforts, such as Superfund sites where the EPA manages environmental contamination cleanup projects, as well as dredging contractors who require efficient dewatering.

Our GEOSTRUX™ tubes are produced using high strength woven fabrics and are manufactured to exact standards and by our in-house fabrication group. GEOSTRUX™ Geotextile Tubes can be fabricated to custom sizes and required engineered specifications to facilitate placement specific to the project. 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. Sediment dewatering with GEOSTRUX™ Geotextile Tubes is a cost-effective and ecologically friendly process when compared to other dewatering methods. Often the sediment is chemically pre-treated with a polymer and/or coagulant before entering the GEOSTRUX™ Geotextile Tubes to increase particle size and accelerate the dewatering process. The result of this chemical action is that the solids contained within the geotextile tubes dewater more rapidly and the discharged water has dramatically less total suspended solids (TSS).

Erosion Control in Coastal & 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.
