Two-D Composite Drainage Geonet

Double-sides coated geotextile draiange net Spec:Complex longitudinal tensile strength:18KN/m weight of geotextile:200g/m2

      The introduction and application of the geocomposite drainage:

1.Compound drainage mesh is made of two dimensional spatial structure plastic nets core double-sided composite geotextile and into a new type of geotextile materials.

2.It has many performances,such as , interted filter, drain away water, ventilation, protection.

3.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.
