| High Light | Landfill Drainage Geocomposite ，Integrated Drainage Geocomposite | ||
Engineered for rapid fluid management in critical barrier applications, our 3D drainage geocomposite combines a rigid polypropylene/polyethylene geonet core with thermally bonded nonwoven geotextiles on one or both faces. This triplanar structure delivers unmatched in-plane flow capacity while preventing soil intrusion—optimizing the performance of overlying geomembranes and soil layers.
Superior Hydraulic Capacity
High Flow Rates: Transmissivity >500×10⁻⁵ m²/sec (ASTM D4716)
100% Core Recovery: Maintains flow under extreme loads (≥500 kPa).
Geomembrane Protection
Stress Distribution: Reduces puncture risk from aggregates/substrates.
Leak Detection: Channels fluids to monitoring points in double-lined systems.
Clog Resistance
Geotextile filters retain soil while allowing unimpeded water passage.
Prevents sediment buildup at geomembrane interfaces.
Installation Efficiency
Pre-assembled composite reduces placement time by 50% vs. traditional gravel drains.
Lightweight rolls (200–400 gsm) enable rapid deployment.
The Triple-Layer Defense:
| Layer | Function | Role in System |
|---|---|---|
| Geomembrane | Primary Fluid Barrier | Prevents seepage (HDPE/LLDPE) |
| 3D Geocomposite | Pressure Relief & Leachate Management | Drains liquids away from liner |
| Geotextile | Filtration/Protection | Prevents core clogging + cushions geomembrane |
Result: Extended liner lifespan, reduced hydraulic pressure, and minimized leakage risk.
Landfill Systems:
• Leachate collection layers (above/below liners)
• Cover gas venting
Mining & Containment:
• Heap leach pad drainage
• Secondary containment leak detection
Infrastructure:
• Retaining wall drainage
• Tunnel waterproofing protection layers
Green Roofs & Plaza Decks:
• Lightweight drainage alternative
