Composite geonet for tunnel drainage
It is a new type drainage material, made of geonet and non woven geotextile.
Geonet thickness from 5mm to 8mm, width from 2m to 4m, non woven geotextile unit weight normally 200g/m² , can be made of made of needle punched polyester geotextile, bonded continuous filament nonwoven geotextile, high strength polypropylene geotextile, length can be produced according to client's request.
Tri-dimension composite geonet for drainage has the property of geotextile and geonet and provide a function system filtration-drainage-protection. The core of net with its unique tri-dimension structure can bear higher compression load in construction and remain the certain thickness, provide good water conductivity.
Landfill drainage, roadbed and road drainage, railway drainage, tunnel drainage, underground structure drainage, the retaining back wall drainage, gardens and sports grounds drainage.
