Geonet-geotextile Drainage Geocomposite
1.Quickly remove subsurface water from pavement.
2.Excellent drainage performance

Geonet-geotextile Drainage  Geocomposite        

 

  Geonet-geotextile Drainage  Geocomposites  are engineered to replace costly, conventional open graded aggregate and/or perforated- pipe subsurface drainage systems. The Geonet-geotextile Drainage  Geocomposite  is created by laminating a filtration geotextile on one or both sides of a Geonet. Geocomposite Drainages have reached acceptance as state-of-the-practice because they provide sufficient in-place drainage and offer reduced material cost, installation time and design complexity over conventional systems.
