UV Resistant 3D Drainage Geogrid Cores 5.0-8.0mm Thickness for Tunnel and Infrastructure Projects
Three-dimensional geogrid cores represent advanced geosynthetic technology, manufactured from high-density polyethylene (HDPE) with carbon black, UV inhibitors, and antioxidants. This specialized extrusion process creates materials with exceptional rigidity and superior drainage capabilities.
- Robust Construction: Features thick vertical ribs with top and bottom oblique ribs for maximum load distribution
- Premium Materials: High-density polyethylene (HDPE) composition ensures long-term durability and chemical resistance
- High Permeability: Rapid drainage capability effectively removes groundwater from road structures
- Dual Functionality: Geotextile layers provide filtration while the core network handles drainage and protection
Ideal for landfill drainage layers and permeability testing, preventing liner system leakage and ensuring environmental safety. Suitable for various slope configurations.
Extensively used in highway and railway drainage systems as roadbed and pavement drainage layers. Effectively manages rainwater runoff and prevents water-related road damage. Also applicable for tunnel and underground structure drainage.
Serves as effective drainage layers for retaining walls, preventing soil settlement and enhancing structural stability through efficient water management.
