Tri-Dimension Compound Geonet
Smart Walls Tri-Dimension Compound Geonet is a high-performance composite drainage material consisting of a three-dimensional HDPE geonet bonded to nonwoven geotextiles on both sides.
The geonet core provides excellent drainage performance, while the geotextile layers act as filtration, separation, and protection media. This combination creates an efficient "Filtration – Drainage – Protection" system suitable for demanding civil and environmental engineering applications.
Designed to withstand high compressive loads while maintaining excellent hydraulic conductivity, the composite geonet is widely used in landfills, tunnels, retaining walls, highways, railways, reservoirs, and other underground drainage systems.
