Geocomposite HDPE Tri Planar HDPE Drainage Geonet Board

Geocomposite HDPE Tri Planner HDPE Drainage Geonet Board

Composite Drainage Geonet Description
Three-dimensional drainage network (also known as three-dimensional geotechnical drainage board, tunnel drainage board, drainage water board) is composed of three-dimensional plastic mesh with one side bonded to filter Geotextile and one side bonded with anti-seepage geomembrane. It can replace the traditional sand and gravel layer. It is mainly used for drainage of landfills, roadbeds and inner walls of tunnels.

3D composite drainage geonet tri-dimension composite geonet for drainage is made of a unique tri-dimension geonets coated nonwoven geotextile on both sides. It has the property of geotextile(filtration function) and geonet (drainage and protection) and remain the certain thickness. Provide good water conductivity.

HDPE Geonet Use
Behind the retaining walls
On erosion control on slope surfaces
Below the building bases
Under the motorways
In reservoir areas
In waste dams
In river improvement projects

HDPE Geonet Packing & Delivery
1. Roll size: 2m*30/50m or 3.9*30/50m
2.The outer package: black or white woven geotextile.
3. Different thickness/ roll size for different qty, special package as per request

HDPE Geonet Feature
1. Drainage is strong. ((the equivalent of about one meter thick gravel drainage)
2. High tensile strength. 
3. To reduce the probability of geotextiles embedded into core, maintain long-term stability of the drainage.
4. Long-term load is under great pressure. ( Can carry about 3000 ka compression load)
5. Corrosion resistance, acid and alkali resistance, long service life.
6. Construction is convenient,shorten the construction period,reduce the cost.
