Composite drainage network
The three-dimensional composite drainage network is made of unique three-dimensional geonet bonded geotextile on both sides. The combination of geotextile (filter function) and geonet (drainage and protection function) provides complete "filter drainage protection" effect.
The unique three-dimensional structure of three-dimensional composite drainage network core can bear high compression load and maintain a considerable thickness in the whole process of use, providing good hydraulic conductivity.
Application:
Landfill drainage; highway subgrade and pavement drainage; railway drainage; tunnel drainage; underground structure drainage, retaining wall back drainage; garden and sports field drainage.
The characteristics of 3D composite drainage network are as follows
It has strong drainage capacity and can bear long-term high-pressure load
High pit tensile strength and shear strength
It can reduce the probability of geotextile embedding into the mesh core, and protect the long-term stable hydraulic conductivity
The three-dimensional composite drainage network can bear more than 2000 kPa compression load
It is far greater than the compressive capacity of ordinary drainage network
