Three-dimensional composite drainage network
Three-dimensional composite drainage network

1.3D geocomposite geonet for landfill 2.Material:high density polyethylene(HDPE) 3.Specification:net cores thickness:5mm

1.Mainly for railways, highways, tunnels, public works, reservoirs, slope protection and other drainage works in the results are obvious.

2.High tensile strength

3.Geotextile fabric to reduce the chances of embedded network core, to maintain long-term stability of the drainage

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.The spec and property indexes of 3D composite drainage net:

NO.
