3D Composite Drainage Geonet
Product Summary
Our 3D composite drainage geonet is engineered for demanding environmental and mining applications, providing efficient liquid drainage and reinforcement. With a unique three-dimensional structure, it combines high compressive strength with excellent flow capacity. Independently tested and certified to GOST 33068-2014, it is trusted in large-scale projects such as the Uzbekistan gold mine tailings pond seepage control.
Key Selling Points
- GOST Certified: Certified to GOST 33068-2014 (Certificate No. POCC CN.32682.04NC中0.OC01.H00838), valid until 2028-05-22, ensuring compliance with EAEU standards.
- High Compressive Strength: Compressive strength ≥500–830 kPa at 10% strain, suitable for deep burial and heavy loads.
- Excellent Drainage Capacity: Drainage capacity 50–120 L/min/m (customizable), efficiently removes leachate and groundwater.
- Chemical Resistance: Acid/alkali resistance ≥90% strength retention, ideal for mining and smelting environments.
- Proven Case: Applied in Uzbekistan gold mine tailings pond (900,000 m²), using innovative textured geomembrane and high-strength PP geotextile.

Models and Options
Available in customizable thickness, mass, and drainage capacity. Please contact our team for specific model designations tailored to your project.
Materials and Structure
Made from high-density polyethylene (HDPE), polypropylene (PP), or polyester (PET). The 3D composite structure integrates a geonet core with geotextiles on one or both sides, providing separation, filtration, and drainage in a single product. The textured geomembrane option uses a five-layer co-extrusion blow molding line with online double-sided texturing, reducing energy consumption by 25%.
Applications
- Tailings pond seepage control in mining
- Metal smelting wastewater containment
- Landfill leachate drainage
- Aquaculture pond liners
- Water conservancy and transportation projects
Customization
We offer custom thickness, mass per unit area, and drainage capacity. MOQ: 5,000 m². Payment terms: 30/70 or 100% T/T. Delivery: FOB/CIF. Pre-shipment testing available.
Case Study: Uzbekistan Gold Mine Tailings Pond
Client: Mining and Smelting Engineering, Uzbekistan
Quantity: 900,000 m² of drainage geonet and geomembrane system
Application: Seepage prevention for tailings pond basin
Solution: 3D composite drainage net combining textured geomembrane (five-layer co-extrusion, online double-sided texturing) with high-strength polypropylene geotextile. The self-developed texturing process achieves molecular-level bonding and reduces production energy by 25%.
Result: Fully met customer requirements for long-term anti-seepage performance in a gold mine tailings pond environment.
