Drainage Tri-dimension Composite Geonet 

Product Description

Tridimension composite geonet for drainage is made of a unique tridimension geonet adhibited geotextile on both 

sides. It has the property of geotextile(filtration function) and geonet(drainage and protection) and provide a function system fitration-drainage protection .The core of net with its unique tridimension structure can bear higher compressiong load in construction 

and remain the certain thickness,provide good water conductivity.

Typical applications

Landfill drainage;roadbed and road drainage; railway drainage ,tunnel drainage,underground structure drainage, the 

retaining back wall drainage , gardens and sports grounds drainage.

Features

Cost-effective substitute for thick layers of coarse-grained soil in drainage applications, providing savings on materials, transportation installation and airspace.Preserves aggregate resources for structural applications where alternative materials can’t be used.Three functions in one unit: filtration, drainage and protection.Rapid installation in comparison to conventional soil drainage layers.Wide range of product combinations allows performance driven product selection at an economical price.Chemically resistant polyethylene geonet and polypropylene geotextile construction provides long life in harsh environments.Exhibits good interface shear strength with adjacent geomembranes and soil, allowing a high factor of safety against sliding
