HDPE Compound drainage nets
Product Description
Compound drainage nets also called 3D geocomposite drainage, 3D geotechnique drainage board. Material:HDPE (high density polyethylene) 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.

Use:
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.
