Thi-Dimension Compound Geonet For Drainage Superior Drainage And Protection System
Product Introduction
Thi-dimension compound geonet for drainage is made of a unique thi-dimension geonet and adhesive with geotextiles on both sides. It has the property of geotextile(filtration) and geonet(drainage and protection), it provide a complete function system" filtration-drainage-protection". The core of net with its unique tri-dimension structure can bear higher compressing load in construction and remanin the certain thickness, provide a good water conductivity.
Product Application
Darinage for the landfill, roadbed and road surface, railway, tunnel, underground structure, back of retaining wall, garden and playground, etc.
Product Property
♦ Excellent drainage function, can bear long time high press load.
♦ High tensile and shear strength.
♦ Reduce the rate of geotextile embedding into the core of geonet, it can protect the water conductivity stable and long time.
♦ Can bear more than 2000kpa compression load.
♦ The anti-compression capacity is much higher than the common drainage geonet.
