Once the solids have dewatered, the sludge dewatering tubes can be cut open and the material can be hauled away and used as fill. Effluent from the geotextile containers is usually clear in color and often returned to the waterway without treatment. Tubes can be customized to any size, and can even be stacked or placed in mobile containers for projects with a limited footprint. Geotubes are versatile, and have been used for decades in lagoons, lakes, rivers, and marinas. Geotubes are an efficient dewatering process that is effective for both large and small dredging projects, especially those with limited areas to work within. However, geotextile tubes can be used as beneficial structures such as shoreline protection (revetments), dikes, breakwaters, or island creation. The primary use of geotextile tubes is for dewatering for dredged slurry. Geotextile containers are made of high-strength, permeable, woven polypropylene fabric that allows excess water to pass through the walls of the tube and retains fine-grained sediments within the unit. The advantage of a geotextile tube is that it increases the options for a dewatering area, which can be a parking lot, along a dam, or an open field. Hydraulic dredging often requires complicated mechanical equipment or the construction of a containment area to dewater the slurry, or sediment and water mixture, that is transported via a pipeline from a dredge. For the client, the bottom line is these enhanced capabilities translate into our ability to accomplish more, at lower operational costs, with less site disruption and quicker project completion.Geotextile tubes, also known as a Geotube®, are one of many innovative tools that River Sand, Inc. The excavator’s features enable Trident to bring dredging and water feature enhancement where heretofore, it was thought too costly, too difficult or unavailable. The dredge’s modern performance provides Trident with capabilities unmatched by others. The Amphibex is simply a better improved tool for the accomplishment of aquatic excavation and revitalization projects. Whereas other hydraulic dredge companies rely on a single-purpose dredge, Trident can deploy its state-of-the-art multipurpose excavation and construction platform to a jobsite to cover a wider range of performance requirements.
