Three-dimensional composite drainage geonet

The three-dimensional composite drainage geonet is manufactured by bonding a specialized three-dimensional geonet to one or both sides of a geotextile, combining the geotextile’s filtration function with the geonet’s drainage and protection capabilities to deliver comprehensive “filtration–drainage–protection” performance. The geonet core’s unique three-dimensional structure can withstand substantial compressive loads throughout its service life while maintaining a consistent thickness, thereby significantly enhancing its hydraulic conductivity.

Product Performance
The three-dimensional composite drainage geonet is manufactured by bonding a specialized three-dimensional geonet to one or both sides of a geotextile, combining the geotextile’s filtration function with the geonet’s drainage and protection capabilities to deliver comprehensive “filtration–drainage–protection” performance. The geonet core’s unique three-dimensional structure can withstand substantial compressive loads throughout its service life while maintaining a consistent thickness, thereby significantly enhancing its hydraulic conductivity.
Main uses
1. Civil engineering and infrastructure construction, including road and railway subgrade drainage, tunnel drainage, and other related works.
2. Environmental engineering projects such as leachate collection and conveyance at solid waste landfills, and impermeable barriers for contaminated soils.
3. Hydraulic and flood-control projects, such as seawall and riverbank protection, and reservoir dam drainage systems.
4. Industrial and energy sectors, including drainage from mine tailings ponds and seepage control and drainage in petrochemical storage tank areas.
