Geotextile tubes are an innovative method of dewatering waste and sludge by-products. Special geotextile fabric is fabricated and seamed into tubes of 3’ to 50’ in circumference by any length. Ports are fabricated into the tubes to allow the tubes to be pumped full. In some cases, polymers are added to the waste in order to flocculate the small particles together to form larger sizes. This helps speed up the dewatering process. The water then pushes through the special geotextile fabric, while the waste is held inside the tube. Once the waste is dewatered, you can cut open the tubes and the waste can then be hauled off and disposed properly. Geotextile tubes are specially designed for each project and have been used in many applications; including dewatering of contaminated sediment, fly ash, quarries, lakes and rivers and many others.
