Detailed Description

Geosynthetic Drainage: 1.Compound drainage nets also called 3D geocomposite drainage, 3D geotechnique drainage board. 2.Compound drainage net is made of three dimensional spatial structure plastic nets core both-sided composite geotextile and into a new type of geotextile materials. 3.Property:inverted filter, drain away water, ventilation, protection. 4.Product features: 1)Row water-borne strong (equivalent to one meter thick gravel drainage). 2)Tensile strength to be high . 3)Reduce geotextiles net core chance of embedded, maintain a long-term and stable drainage. 4) Long-term under great pressure and load (can bear about 3000Ka compression load) 5)Corrosion resistance, acid and alkali resistant, long service life. 6)Construction is convenient, shorten the construction period, lower cost. 5.Compound drainage nets is mainly used for railways, highways, tunnels, municipal engineering, reservoir, revetment in drainage engineering, such as the obvious NO.
