3D Composite Drainage Geonet is engineered for high performance drainage in infrastructure projects such as tunnels and highways. The composite structure provides a reliable pathway for water flow while preventing soil intrusion.
The core geonet creates continuous channels for water movement, while the bonded geotextile acts as a filtration barrier. This dual function design ensures stable drainage even in high pressure environments.
It is particularly effective in tunnel lining systems, where space is limited and traditional drainage materials are difficult to install. The lightweight design reduces transportation and installation costs.
