                              Three-dimensional composite geonet for landfill usuage

1.Product description:

3D composite geonet for drainage is made of a unique tri-dimension geonet adhibited geotextiles 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.

2.Product use:

Mainly used for railways, highways, tunnels, municipal engineering, reservoir, slope protection and drainage engineering effect is remarkable.

3.Product features:

1. Strong drainage (equivalent to one meter thick gravel drainage).
2. High tensile strength.
3. Reduce soil fabric embedded into core probability, maintain long-term stability of the drainage.
4. Long-term under high load (can bear about 3000 ka compression load).
5. Corrosion resistance, acid and alkali resistant, long service life.
6. Construction is convenient, shorten the construction period, reduce cost.

4.The contrast of tri-dimension composite drainage net and natural grit drainage layer:

Application Tri-dimension composite geonet for drainage Natural gravel
Conducting and discharging Pass through strict quality control production line and have stable performance and good property of conducting water The traditional gravel have complex composition. Its actual drainage property is much lower than laboratoty data for its contains of sand and dust.
Load/protection Light, no more extual 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, can 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 destroyed when people mine gravel.
