Drainage Geocomposite 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:

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