Introduction of Tri Dimensional Composite Drainage Geonet:
Tri-dimensional composite drainage geonet is made of a unique tri drimension geonet adhibit geotextile on both sides. It has the property of geotextile(filtration function) and geonet (drainage and protection) and provide a function system “filtration—drainage—protection”. The core of net with its unique tri-dimension structure can bear higher compressing load in construction and remain the certain thickness, provide good water conductivity.
Application of Tri Dimensional Composite Drainage Geonet:
Landfill drainage; roadbed and road drainage; railway drainage ,tunnel drainage, underground structure drainage, the retaining back wall drainage, gardens and sports grounds drainage.

The contrast of Tri dimensional composite drainage geonet and natural grit drainage layer
Application | Tri-dimension composite geonet for drainage | Natural Gravel |
Conducting and discharging Water and gas | Pass through strict quality control production line and have stable performance and good property of conducting water | The traditional gravel have complex composition and its drainage property change with its attribute. Its actual drainage property is much lower laboratory data for its contains of sand and dust. |
Load/Protection | Light, no more extral load on geomembrane and waste. Anti-pull, anti-compress, anti-impact and can prevent geomembrane from damage | Pressure on the waste, the keen stone can puncture and damage geomembrane. Often need other safeguard, such as thicker geotextile. |
Function | Four functions: drainage, separation, filtration and protection | Only drainage function, easy be blocked, and need accessorial filtration system. |
Construction and installation | Fast installation, easy for construction, without heavy machinery and professionals. Construction speed is 5-10 times of gravel. | Slow installation, bulky and heavy, need heavy machinery. High cost and have more difficulties with slope degree is more than 1V:4H. |
Environment | Raw material is polyethylene, nontoxic, no pollution, 100% recyclable products. | Relatively speaking, the gravel is scarce and precious resources. The ecological environment will be destroied when people mine gravel. |
Durability | Good anti-erosion, antioxidation, anti-atmospheric media and rain water. It have long-term and the best drainage property if used them along with the geotextile. | Be easily blocked, has poor durability. |
