Introduction:
Our High-Flow Geonet Drainage Layer is an engineered three-dimensional polymer drainage core designed for maximum hydraulic conductivity in demanding civil and environmental applications. Manufactured from virgin HDPE/PP resins, this geosynthetic product features a patented tri-planar structure that outperforms traditional drainage aggregates in both flow capacity and long-term reliability.
Core Technology:
Triangular core design creates optimized flow channels (99% void space)
Dual-directional ribs provide structural stability while maintaining flow paths
UV-stabilized formulation with 2-3% carbon black for outdoor durability
