Geotextile Tube
Product Introduction
A geotextile tube is a tubular bag made of high-strength, high-performance polypropylene (PP) woven geotextile. It utilizes physical filtration principles to fill, dewater, and consolidate sludge, mud, and various wastes, making it the most efficient and economical dewatering and reinforcement solution in modern municipal, mining, and coastal engineering projects.
Geoleed employs a special weft-and-warp interlacing process, achieving longitudinal and transverse tensile strengths of 100kN/m - 1000kN/m, ensuring no pipe bursting or deformation under high-pressure pumping conditions.
The equivalent pore size (AOS) can be customized (0.1mm - 0.5mm) based on the mud composition provided by the customer, achieving a balance between high filtration efficiency and high solids rejection rate.
Working Principle
How It Works:
Filling: Slurry mixed with flocculant is pumped into the tubing.
Dewatering: The unique, regularly spaced pores of the tubing trap solid particles while allowing water to seep out freely, reducing volume by up to 90%.
Consolidation: After the water is drained, the material inside the tubing transforms into stable solid blocks, which can be used as backfill material or safely transported away.
The operation of geotextile bags is a dynamic physical filtration process:
Stage 1: Filling A slurry pump is used to pump a mixture of water and solid materials (such as dredged silt, slag, or sewage sludge) into the geotextile bag.
Principle: The geotextile bag is made of high-strength synthetic fibers (usually woven geotextile) capable of withstanding the high hydraulic pressure generated during pumping.
Chemical Assistance: To improve efficiency, a flocculant (PAM) is usually added to the slurry before pumping, causing tiny particles to quickly aggregate into clumps, facilitating water separation.
Stage 2: Dewatering This is the most remarkable physical process of the geotextile bag.
Principle: The pores of the geotextile bag fabric are specially designed to allow water to drain while trapping most solid particles.
Effect: As water seeps through the fabric surface, the solid content inside the geotextile bag increases, and its volume gradually decreases. This process acts like a giant **"squeeze filter"**.
Phase Three: Consolidation After a significant amount of water has been drained, the solid material inside the tubular bag is further compacted under the combined effects of gravity and fabric tension.
Result: What remains inside the tubular bag is dry, solid material. In the case of revetment projects, these tubular bags become extremely heavy and stable, forming a robust structure.

Application Case
Application
Typical Application Scenarios (Target Applications in Saudi Arabia)
Coastline Protection and Artificial Islands: Serving as core dikes and cofferdams in coastal projects such as the Red Sea Project, replacing traditionally expensive stone materials.
Mining Tailings Treatment: Solidifying and dewatering tailings from Saudi gold and phosphate mines, significantly reducing the land area required for tailings ponds.
Oilfield Sludge Treatment: On-site solidification treatment of oilfield drilling mud, recovering clean water to meet environmental emission standards.
Dredging Projects: Rapid drying of bottom sediment after dredging in ports and canals.
