3D Composite Drainage Net – Integrated Filtration-Drainage-Protection System
Product Overview
Made of a unique 3D geonet bonded with geotextiles on both sides, this composite drainage net combines filtration, drainage, and protection functions into a complete integrated system. The innovative 3D net core structure maintains substantial thickness under high compressive loads while providing excellent hydraulic conductivity throughout its service life.
Key Features
- Strong drainage capacity: Unique 3D channel design ensures rapid water discharge and maintains stable hydraulic conductivity long-term
- High compressive strength: Withstands over 2000 Kpa compressive load, significantly higher than ordinary drainage nets, with minimal deformation under pressure
- Excellent mechanical properties: High tensile and shear strength to withstand construction tension and external impact
- Anti-clogging design: Reduces geotextile embedding into net core, ensuring stable drainage performance and extended service life
Application Scenarios
- Landfill leachate drainage systems
- Groundwater drainage projects
- Closure surface infiltration port drainage
- Highway subgrade and pavement drainage
- Railway drainage systems
- Tunnel drainage applications
- Underground structure drainage
- Retaining wall backfill drainage
- Garden and sports field drainage
Installation Guidelines
Lightweight and flexible design facilitates easy transport and installation. The material can be custom-cut to match project dimensions and shapes. Lay on clean, flat base surfaces with 10-15cm overlap between adjacent sections. Secure using staples or adhesive methods. Compatible with geomembranes and other materials to create comprehensive drainage and anti-seepage systems.
