Geo Tubes


Geo Tubes

The Geo tubes are also known as geo bags which used for sludge dewatering projects of different sizes because of their simplicity and low-cost factor.

They are containers that are hydraulically filled with a slurry mix of sand and water. The hydraulic pressure helps to transport the sand along the inside of the tube, while the water will dissipate through the permeable engineered fabric, then the sand will settle out within the container by gravity.

The Geotube system can be applied in different industries, including shoreline protection, land reclamation, island creation, wetlands creation, construction platforms, revetments, dykes, groynes, and offshore structures.

The system doesn’t operate with belts, gears, or complicated mechanics. Also, they are available in different sizes, depending on the volume and space requirements. They can even be mounted in mobile roll-off containers that can be transported around your property as necessary.

Geo Tube is a cost-effective sealing solution for dewatering and descaling or protection. 


The geotubes containers offer many benefits, including:

• High flow rate which allows residual to dewater, leaving behind the solids

• Custom fabricated with seaming techniques that can withstand pressure during pumping operations

• It can be custom designed and fabricated. It is a specially engineered system through advanced textile technologies

• It is an excellent solution for revetments, breakwaters, dykes, and groynes

After the delivery and geotube installation, the sludge is treated with specialist polymers and then pumped into the containers. 

Consequently, clear effluent water is drained, leaving the solid within the container. When full, the containers are disposed of at a landfill, or the sludge can be removed and land-applied.


The process is simple yet effective, which makes it ideal for the:pulp and paper industries

•  Pulp and paper industries

•  Primary and secondary lagoon cleanout

•  Mining and mineral processing to remove railings

•  Coal sludge

•  Municipal wastewater treatment plants

•  Marine remediation

    •  Power & utility

    •  Pulp & paper

    •  Light industrial

    •  Agriculture including the dairy industry, piggeries, and abattoirs

    •  Aquaculture
