Composite Drainage Network
High drainage efficiency: The unique structure accelerates water flow.
Strong compressive resistance: Maintains shape under load.
Corrosion & aging resistance: Long service life.
Convenient construction: Lightweight, flexible, and quick to install.
Good filtration: Blocks soil while allowing water through, preventing blockages.
Product introduction
A Composite Drainage Network ( Geocomposite Drainage Liners ) is a new type of dewatering geotechnical material, which is designed to complement or replace sand, stone and gravel. It consists of a HDPE geonet heat-bonded with one side or both sides of nonwoven needle punched geotextile. The geonet has two structures. One structure is bi-axial structure and the other is tri-axial structure.
