Geotextile Tube (Geotube) - High-Quality Solutions from China Suppliers & Factory for Environmental Projects
Core Principle WAZ PLASTIC
Utilizes a precision "water-permeable but soil-tight" woven structure. Through hydraulic filling of slurry/sand + pressure filtration, it achieves:
💧 Dewatering & Volume Reduction
Water permeates out, >99% solids retained. Moisture content reduced from 95% to 40%–60%, volume reduced by 60%–90%.
🏗️ Solidification & Structure Formation
Forms a continuous flexible structure that adapts to settlement, resists waves, scouring, and sliding.
🌿 Ecological Closure
In-situ sludge solidification and resource utilization, no secondary pollution.

Frequently Asked Questions
Q What is a geotextile tube and how does it work?
A geotextile tube is a large, permeable fabric container made from high-tenacity woven polypropylene. It works by being hydraulically filled with slurry or sand. The woven structure allows water to permeate out while retaining over 99% of solids inside, achieving significant dewatering and volume reduction.
Q What level of dewatering can be achieved with geotextile tubes?
Geotextile tubes can reduce the moisture content of sludge from approximately 95% down to 40%–60%, resulting in an overall volume reduction of 60%–90%. This dramatically reduces disposal costs and makes the dewatered material easier to handle or reuse.
Q What sizes and specifications are available?
WAZ PLASTIC geotextile tubes are fully customizable. Available diameters range from 1 m to 11 m, and lengths can extend from 10 m to over 100 m. Material weight ranges from 450 to 1000 g/㎡ with tensile strength between 85–220 kN/m, suitable for a wide variety of project scales.
Q Are geotextile tubes suitable for chemical or marine environments?
Yes. The tubes are manufactured from UV-stabilized PP/PE composite materials with excellent chemical resistance across a pH range of 2–13. They are designed to withstand harsh coastal, marine, and industrial environments, with a service life of 15–70 years depending on conditions.
Q What types of projects are geotextile tubes most commonly used for?
Geotextile tubes are widely used in coastal and port engineering (revetments, breakwaters, land reclamation), hydraulic and river projects (dike reinforcement, ecological restoration), environmental applications (sludge dewatering, landfill caps), and municipal works (temporary cofferdams, flood control, soft ground improvement).
Q How do WAZ PLASTIC geotextile tubes compare in cost to traditional methods?
WAZ PLASTIC geotextile tubes can reduce overall project costs by more than 30% compared to conventional dewatering and containment methods. Key savings come from lower equipment investment, minimal land requirements, reduced material transportation, and faster on-site installation — all without compromising structural performance or environmental compliance.
