![]() ![]() River Sand pumped material into two Geotube® containers using an 8” hydraulic dredge. worked with TenCate™ Geotube’s® research and development team to perform QA/QC analysis on their Geotube® products at a field scale. ![]() These polymers are environmentally safe, and increase the viability of dredging with geotextile containers that reduce overall cost. also uses a polymer injection system to increase the coagulation and flocculation of sediments thereby decreasing the time needed to dewater. River Sand can utilize the geotextile tubes for both industrial and municipal sludge dewatering as part of our environmental remediation projects. can provide you with the information and budgetary costs for your dredging project, whether it is a lagoon, boat dock, pond, lake, or stream. 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. Geotextile tubes, also known as a Geotube®, are one of many innovative tools that River Sand, Inc. ![]()
