GEOTUBE® GT500 Dewatering Container – (with Sleeve & Top Cover)

GEOTUBE® containers manage mine tailings, coal sludge, and settling pond sediments cost-effectively. Custom-sized units fit between existing structures and can be stacked to maximise capacity within a constrained footprint. Dewatered tailings can be stored in place, used structurally to raise berms, or removed once consolidation is complete — all without expensive dredging or mechanical dewatering equipment.

GEOTUBE® is the proven solution for dewatering dredged sediment from harbours, rivers, canals, and dams. Large-format units handle the high volumes generated by capital and maintenance dredging programmes. Marine and underwater container variants allow dewatering to be conducted at or very near the dredging site, significantly reducing transport and disposal costs.

GEOTUBE® simplifies sludge dewatering at sewage treatment works and industrial wastewater facilities, increasing effective drying bed capacity and providing a low-maintenance alternative to belt presses and centrifuges. After flocculant treatment, sludge is pumped into the container where solids are retained and water seeps through the fabric. The process is repeated until the unit reaches capacity, with no mechanical components to operate or maintain.

On mining sites where water is a limited and valuable resource, GEOTUBE® technology combined with polymer conditioning releases clean process water from suspended solids the moment they enter the tube. The resulting filtrate is typically of sufficient quality to be recirculated directly into mine processing operations, reducing freshwater demand and supporting closed-loop water management systems.cilities.

GEOTUBE® dewatering technology is suited to recovering precious metals from barren and pregnant solution ponds in heap leach operations. By capturing and containing dewatered slurries that still hold gold, silver, or other valuable metals, the cost of treating mine waste can be offset and converted into a recoverable income stream. The system has been successfully applied at gold and silver mines in North America and Australia.

Standard large-format dewatering containers custom fabricated in GT500 or GT1000M fabric to project-specific circumference and length. Filled hydraulically via patented Eyeport inlet fittings. Suited to mining tailings, dredged sediment, industrial wastewater, and large-volume sludge management. Suitable for permanent in-place containment or cut-open solids removal.

Compact 1m x 1m x 1m dewatering bag in GT500 woven polypropylene fabric. Available with open top or closed top with fill port sleeve. Tensile strength 72 kN/m (MD) and 95 kN/m (CMD), seam strength 65 kN/m, opening size O90 of 250 microns, and water permeability of 30 l/s/m2. Suited to small-volume dewatering, sampling applications, and stormwater sediment management.

Prefabricated GEOTUBE® units fitted into standard roll-off box containers with volumes from 9.8 to 23 m3 depending on container size. Completely prefabricated and ready for use - unroll and connect to fill line. Once filled, the entire system can be transported to a landfill or disposal facility. Suited to operations requiring mobile dewatering capacity across multiple site locations.

Specialised GEOTUBE® units for underwater installation using steel frames, suited to nearshore dredging, harbour sediment management, and marine containment where land-based deployment is not available. Units are lowered to the waterbody floor in the frame before hydraulic filling begins.
