3D Drainage Geogrid Mesh 5.0-8.0mm Thickness with 8-14 KN/m Tensile Strength for Civil Engineering
The 3D Drainage Geogrid Mesh is an advanced composite geotechnical material engineered for superior drainage performance combined with comprehensive filtration and protection capabilities.
This innovative drainage solution features a three-dimensional geotechnical mesh core with needle-punched perforated non-woven geotextile fabric securely adhered to both sides. The structural design incorporates thick vertical ribs with diagonal reinforcement ribs at both top and bottom surfaces.
- Landfill drainage systems
- Roadbed and road surface drainage
- Railway and tunnel infrastructure
- Underground structural drainage
- Retaining wall back drainage
- Landscaping and playground drainage
The 3D composite drainage network delivers exceptional drainage efficiency while providing secondary functions of soil separation and base reinforcement. The material maintains consistent thickness under high compressive loads up to 500KPa while preserving optimal water permeability throughout service life.
This geogrid mesh provides complete "filtration-drainage-protection" functionality, making it suitable for demanding civil engineering applications including highways, railways, tunnels, municipal projects, reservoirs, and slope protection systems.
