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...]
Geotextile Tube Dewatering
IAI has installed 680,000 lineal feet of geotextile tubes (and counting), to dewater 4.9 million cubic yards of material, in projects throughout the United States. We have used geotextile tubes to dewater both clean and contaminated sediments, industrial waste, coal ash (CCR), biosolids, sludge, and industrial waste products. See examples of our geotextile tube dewatering projects, below.
The Cedar Creek OU2A environmental dredging project was conducted to clean up PCBs-contaminated marine sediments from Cedar Creek, in Cedarburg, Wisconsin. IAI was a member of a team of contractors, who were selected to perform this Remedial Action project, after submitting an alternate proposal for high production hydraulic dredging to geotextile … [Read more...]
Tailored Sediment Removal and Treatment Equipment Make a Big Impact on a Small Project “Use the correct tool for the job,” is a common construction safety rule, reminding us that the right equipment, used properly, will produce the safest, most efficient result. Not only is it important to use the right type of equipment, but also the right size. The … [Read more...]
IAI was selected by We Energies to remove and dispose of accumulated sediment and coal combustion residuals (CCR) from a pond at the Presque Isle Power Plant in picturesque Marquette, Michigan. IAI provided general contractor services, and self-performed the geotextile tube dewatering portion of the work. Approximately 4,000 cubic yards of coal … [Read more...]
IAI utilized a 445 horsepower, 12 inch diameter auger dredge with a 12 inch diameter inline booster pump to remove coal fines from an impoundment that was filling to capacity at a mining facility in southern Illinois. During day time hours, mine flow was combined with the dredge flow feeding the geotextile tubes dewatering operation, for a total flow of … [Read more...]
This remedial action project utilized hydraulic dredging to remove 145,377 cubic yards of contaminated sediment from the Grand Calumet River. IAI was responsible for the sediment dewatering and water treatment portions of work. The sediment dewatering pad was installed over a brownfield site in East Chicago, where the contaminated sediment was … [Read more...]
