composite geonet for drainage  Company: Huatao Group Limited Website:   Email:    sandy (at) Skype: huatao-group Mob / WhatsApp: +86 177 311 89774 Contact : Sandy Qin   Description: Tri-dimension composite genet for drainage is a new type of geosynthetics. Its made of atri-dimension geonet coated with geotextile on both sides. Network core consists of a tri-dimension thick vertical rib, and a rip on top and bottom . It can drain underground water quickly, also there is a protection system,which can block the capillary water under high load. At the same time, it can also reinforce and isolate of foundation.   Specifications: core thickness: 5 mm - 8 mm; Width: 2 - 4m, composite geotextile: short fiber needle punched geotextile, filament spunbonded needle punched geotextile, the length at request.   Typical Application: drainage in landfill; roadbed; railway,tunnel,underground structure,the retaining back wall, gardens and sports grounds.   Features： Excellent drainage function, can bear long time hige press load High tensile and shear strength Reduce the rate geotextile embedding into the core of geonet, can protect long time stable water conductivity Tri-dimension composite geonet for drainage can bear more than kpa compression load Its anti-compression capacity is much larger than common geonet for drainage.   Properties: Tri-dimension composite geonet for drainage is made of a unique tri-dimension geonet coated with geotextile on both sides. It has the property of geotextile(filtration) and geonet (drainage and protection) and provide a function system of“filtration-drainage-protection”. The tri-dimension structure can bear higher load in construction and remain certain thickness,strength and excellent in water conductivity.   Tri-dimension composite geonet for drainage Datasheet Drainage netwrok core units Specification Unit weight g/m2 750 1000 1300 1600 Thickness OV=20kpa mm 5.0 6.0 7.0 7.6 Hydraulic conductivity m/s K x 10 -4 K x 10 -4 K x 10 -3 K x 10 -3 Elongation % ＜50 ＜50 ＜50 ＜50 Tensile strength ( core network) KN/m 8 10 12 14 Geotextile g/m2 200-200 200-200 200-200 200-200
