Drainage Geocomposite
1.Quickly remove subsurface water from pavement
2.Build to last
3.Excellent drainage performance

                                              Drainage  Geocomposite 
Production Description     

  Drainage  Geocomposites  are engineered to replace costly, conventional open graded aggregate and/or perforated- pipe subsurface drainage systems. The Geocomposite Drainage  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.
