3D Composite Drainage Net with High Tensile Strength ≥16kN/m, Excellent UV Resistance, and Anti-Clogging Design for Landfill and Roadbed Applications

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.

• 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

• 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

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.
