How Geotube® systems work.

The Geotube® technology is characterised by three stages:

• Containment: A high strength permeable fabric with uniquely designed retention properties is fabricated into Geotube® containers that can be filled with fine grain sludge, hazardous contaminated soils, or dredged waste materials.
• Dewatering: Excess water drains from the Geotube® containers through the small pores in the fabric resulting in effective dewatering and efficient volume reduction of the contained material. This volume reduction allows for the repeated filling of the Geotube® container. In many cases the decanted water is of a quality that can be returned to native waterways or for reuse.
• Consolidation: After the final cycle of filling and dewatering, the retained fine grain materials can continue to consolidate by desiccation because the residual water vapor escapes through the fabric.
