Product Description
Three Dimensional Composite Drainage Mesh 7mm
This high-performance drainage geonet features a 7mm thickness and exceptional corrosion resistance, providing superior drainage solutions for demanding engineering applications.
Product Overview
The 7mm three-dimensional composite drainage mesh is manufactured from high-density polyethylene (HDPE) using specialized extrusion molding technology. Its unique three-layer structure features rigid longitudinal ribs that create efficient drainage channels, while cross-arranged upper and lower ribs provide structural support to prevent geotextile embedment.
Key Applications
Ideal for railway systems, highway construction, tunnel projects, municipal infrastructure, reservoir management, and slope protection. This material effectively replaces traditional gravel drainage layers while offering superior performance in landfill drainage, roadbed construction, and tunnel lining applications.
Technical Advantages
- Exceptional Drainage Capacity: Equivalent to 1-meter thick gravel drainage system
- High Tensile Strength: Maintains stable performance under extreme pressure conditions
- Corrosion Resistance: Acid and alkali resistant with extended service life
- Structural Integrity: Special design minimizes geotextile embedment in drainage channels
