Product inroduction


3D composite drainage geonet is made of special geonet with double -side bonded geotextile.The combination of geotextile (reverse filtration) and geonet(drainage and protection) provides a cpmplete "reverse filtration-drainage-protection" effect.The special 3D structure of the mesh can with-stand high compressive loads during the entire use process,and can maintain a considerable thickness,provide good permeability.It can replace traditional sand and gravel layers,and is mainly used for drainage of landfills,roadbeds and inner walls of tunnels.

Product Feature

1.High drainage and tensile strength
2.Reduce the probability of geotextiles being embedded in the mesh core
3.Maintain long-term stable drainage
4.Withstand high pressure load for a long time,corrosion resistance,acid and alkali resistance

5.Convenient construction ,shortening construction period and reducing cost


 Performance

 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.

 7.  Excellent drainage function, can bear long time high press road

 8.  High tensile and shear strength

 9. Can bear more than 2000KPa compression load

10.Anti-compression capacity is much larger than common geonet for drainage.

Advantage of this 3D Composite Drainage Geonet

1,It is laid between foundation and base, which is used to discharge water between foundation and base, block capillary water and effectively combine it into the marginal drainage system.This structure automatically shortens the foundation drainage, drainage time significantly shorter, and can make the decrease in the number of the use of the material selection of foundation can be used with more fine material, low permeability of materials.Can extend the life of the road.
2,
In the base layer laying three-dimensional composite drainage network to prevent the base of fine material into the ground floor, that is, play a role in isolation. Aggregate grass will enter the upper part of the geonet in a limited degree. In this way, the composite geotextile network also has a potential to limit the lateral movement of the aggregate base, in this way, its role is similar to the strengthening of the geogrid. In general, the tensile strength and rigidity of the composite geotechnical drainage network is superior to many geogrids for foundation reinforcement, and this restriction will improve the supporting capacity of the foundation.
3,
Road aging, cracks formed, most of the rain will enter the section. In this case, the three-dimensional composite drainage network directly laying under the road, instead of drainage of the foundation. The three-dimensional composite drainage network can be collected before the water enters the foundation / sub-base. But also in the three-dimensional composite drainage network at the bottom of a layer of film, to further prevent the water into the foundation. Whether it is for rigid roads or flexible road systems, this structure can extend the life of the road.
