Hdpe Geonet 800g/m2 HDPE 3D Three-Dimension Composite Drainage geonet
Three Dimension Drainage Net (or being named three civil drainage board, tunnel drainage board, drainage board) which has the characteristic of good water transmission, against high pressure and microorganism, anti-UV. It can instead of the traditional gravel sand. It is used for the drainage of the rubbish filling site, road base and the inside of the tunnel which is consisted with plastic net and permeated geotextile both sides.
The spec and property indexes of 3d composite drainage net:
| NO. | Item | Unit | Standard value | Notes |
| 1 | Complex unit area quality | g/m2 | ≥1400 | |
| 2 | Non-woven unit area quality | g/m2 | ≥200 | |
| 3 | Complex thickness | mm | ≥7.0 | |
| 4 | Nets core thickness | mm | ≥5.0 | |
| 5 | Complex longitudinal tensile strength | KN/m | ≥18.0 | |
| 6 | Complex transverse tensile strength | KN/m | ≥15.0 | |
| 7 | Nets core tensile strength | KN/m | ≥15.0 | Vertical and horizontal |
| 8 | Peel strength of nets core and non-woven | KN/m | ≥0.3 | |
| 9 | Complex hydraulic conductivity | m2/s | ≥1.2×10-3 | |
| 10 | Non-woven to permeability coefficient | cm/s | ≥0.3 |
Three-Dimension Composite Drainage geonet Application
drainage in landfill; roadbed; railway , tunnel,underground structure, the retaining back wall, gardens and sports grounds.
Three-Dimension Composite Drainage geonet Features
Excellent drainage function, can bear long time hige press load
High tensile and shear strength
Reduce the rate geotextile embedding into the core of geonet, can protect long time stable water conductivity
Tri - dimension composite geonet for drainage can bear more than kpa compression load
Its anti-compression capacity is much larger than common geonet for drainage.
Three-Dimension Composite Drainage geonet Properties
Tri-dimension composite geonet for drainage is made of a unique tri-dimension geonet coated with geotextile
on both sides.
It has the property of geotextile(filtration) and geonet (drainage and protection) and provide a function system of“filtration-drainage-protection”.
The tri-dimension structure can bear higher load in construction and remain certain thickness,strength and
excellent in water conductivity.
