    Drainage Geocomposite: High-Performance Core for Integrated Containment Systems for Landfill, roadbed, railway, tunnel, retaining wall

    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.

    Key Advantages

    1. Superior Hydraulic Capacity

      • High Flow Rates: Transmissivity >500×10⁻⁵ m²/sec (ASTM D4716)

      • 100% Core Recovery: Maintains flow under extreme loads (≥500 kPa).

    2. Geomembrane Protection

      • Stress Distribution: Reduces puncture risk from aggregates/substrates.

      • Leak Detection: Channels fluids to monitoring points in double-lined systems.

    3. Clog Resistance

      • Geotextile filters retain soil while allowing unimpeded water passage.

      • Prevents sediment buildup at geomembrane interfaces.

    4. Installation Efficiency

      • Pre-assembled composite reduces placement time by 50% vs. traditional gravel drains.

      • Lightweight rolls (200–400 gsm) enable rapid deployment.


    Synergy in Barrier Systems: The Integrated Solution

    The Triple-Layer Defense:

    LayerFunctionRole in System
    GeomembranePrimary Fluid BarrierPrevents seepage (HDPE/LLDPE)
    3D GeocompositePressure Relief & Leachate ManagementDrains liquids away from liner
    GeotextileFiltration/ProtectionPrevents core clogging + cushions geomembrane

    Result: Extended liner lifespan, reduced hydraulic pressure, and minimized leakage risk.


    Critical Applications

    • 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
