IAI installed a geotextile tube wall, 11 FT tall and 1,900 FT long, along the perimeter of a coal ash pond, for this project. The geotextile tubes that made up the wall were filled with dredged coal ash from the pond, conditioned with polymer, and pumped into the geotextile tubes at a rate of approximately 1,500 GPM. IAI's team devised a method for … [Read more...]
