    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.

    Key Material & Performance

    WAZ PLASTIC
    ● Material High-tenacity PP (450–1000g/㎡), PP/PE composite, UV-stabilized
    ● Tensile Strength 85–220 kN/m (MD/CD)
    ● Aperture (O90) 15–0.5 mm
    ● Permeability 1×10⁻² – 1×10⁻⁴ cm/s

    Frequently Asked Questions
    1What 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 filled with a slurry or sand mixture through hydraulic pumping. The "water-permeable but soil-tight" woven structure allows water to filter out under pressure while retaining over 99% of solids inside, resulting in a dewatered, solidified mass that forms a stable flexible structure.
    2How much can geotextile tubes reduce sludge volume?
    Geotextile tubes are highly effective at volume reduction. After the dewatering process, the moisture content of the sludge is reduced from approximately 95% down to 40%–60%, resulting in an overall volume reduction of 60%–90%. This dramatically reduces disposal costs and the footprint required for sludge management.
    3What sizes and custom specifications are available?
    WAZ Plastic offers a wide range of custom sizes to suit different project scales. Tube diameters range from 1m to 11m, and lengths can be produced from 10m up to 100m or more. Material weights range from 450 to 1000 g/㎡ with tensile strengths of 85–220 kN/m, ensuring the right specification for every application.
    4Are geotextile tubes environmentally safe?
    Yes. The geotextile tube system uses a fully enclosed treatment process that prevents secondary pollution. Sludge is solidified and treated in-situ, enabling resource recycling and ecological closure. The material is UV-stabilized, chemically resistant across pH 2–13, and vegetation-friendly, making it suitable for environmentally sensitive projects.
    5What industries and project types can use geotextile tubes?
    Geotextile tubes are highly versatile and are used across coastal and port engineering (revetments, breakwaters, land reclamation), hydraulic and river projects (dike reinforcement, dredging, ecological restoration), environmental and waste management (municipal and industrial sludge dewatering, landfill caps), and municipal applications (temporary cofferdams, soil improvement, flood control).
    6What certifications and quality standards does WAZ Plastic comply with?
    WAZ Plastic geotextile tubes are manufactured in compliance with internationally recognized quality standards including ISO, ASTM, and GB (Chinese National Standards). Full technical support is provided, including installation guidance, chemical compatibility advice, and quality control assistance, ensuring every project meets the required performance and safety benchmarks.
