Description

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:

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.

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
