What�ll They Think of Next? Dewatering Contaminated Slurries Using Geotextile Tubes
Sediment must be dredged from the bottom of waterbodies to maintain their capacity and navigability. Dredging, by its nature, involves the removal of highwater-content slurries and also helps preserve...
Geotextile Tube Dewatering
Geotextile tubes are made of high-strength, permeable geotextile that, when filled with a slurry, allow water to drain from the tubes while retaining the solids. They can be prefabricated...
