Product Description

The three-dimensional composite drainage geonet is an innovative geosynthetic material featuring a unique structural design. It consists of a three-dimensional geotechnical mesh core with thick vertical ribs and oblique top/bottom ribs, bonded to two needle-punched perforated non-woven geotechnical fabrics on both sides.

Applications

This drainage geonet is engineered for diverse civil and environmental engineering applications:

Railway, highway, and tunnel drainage systems
Municipal engineering and reservoir projects
Retaining slope stabilization and water management
Landfill surface water diversion and gas collection layers
Leachate collection and drainage systems (LCRS)
Garden and sports field drainage solutions

Key Properties

High tensile and shear strength for long-term load bearing
Maintains consistent thickness under pressure
Excellent hydraulic conductivity for efficient drainage
Superior corrosion resistance and acid/alkali tolerance
Extended service life in demanding environments
