Geocomposite Strip Drain
Geocomposite Strip Drain Products is a composite geosynthetics consisting of drainage board and geotextile. The concave-convex structure of the drainage board can play the role of drainage, and the geotextile can protect the drainage board and filter.
Geocomposite strip drain is a kind of Strip Drainage Products, widely used in strip drainage system, especially slope drainage system and geocomposite wall drain system.
The geocomposite drainage strip Products is a composite geosynthetics of drainage boards and geotextile.

Geotextiles: Filant geotextiles or staple fiber needle punched geotextiles can be selected. Filament geotextiles are recommended for Geocomposite strip drain.
Filament geotextile VS Short fiber needle punched geotextile
1. The friction coefficient of the filament geotextile is significantly larger than that of the polyester staple fiber geotextile.
2. The puncture resistance of filament geotextile is better than that of polyester staple fiber geotextile
3. Filament geotextiles and polyester staple fiber geotextiles are different in fiber morphology and production process. The porosity of polyester filament geotextiles is larger and the porosity of polyester staple fiber geotextiles is smaller. Therefore, the possibility of fouling of polyester filament geotextiles is less likely.
