- Description
- Features
- Application
- Technical Parameters
Composite Drainage consists of a drainage core and a high performance geotextile. The geotextile serves to retain soil while allowing water to pass from the soil to the core and is securely bonded to the core to prevent intrusion of the fabric into the core during service. It's not recommended for use over Waterproofing membranes.
- Excellent drainage performance
- High tensile and high shear strength
- Can bear long time high press load
Composite Drainage is designed to collect and transport water and recommended for use on foundation walls, retaining walls, bridge abutments, tunnels, earth sheltered structures, plaza decks, soil retention systems and planters.
It is widly used on the rubbish-landfills,high way subfrade and pavement,railwy,tunnel,gardon,playfrounds and other underground structures.
