3D Composite Drainage Network
3D composite drainage network (Wikipedia, Geocomposite) is available in both single-sided and double-sided products with geonet core thickness from 3mm to 10mm, and geotextile fabric ranging from 100gsm to 300gsm. This drainage network has excellent liquid transmittivity ability. It can be widely used in a lot of drainage applications such as landfill, retaining walls, dams, foundation and so forth.
Our Shanghai Yingfan Environmental Engineering Co., Ltd. is a 3D composite drainage network and other earth work construction material supplier in China. We don’t only provide 2D composite drainage network but also can provide 3D composite drainage network.

Drainage Geocomposite Introduction
Drainage Geocomposite is available in both single-sided and double-sided products with geonet core thickness from 3mm to 10mm, and fabric ranging from 100gsm to 300gsm. The non-woven geotextile is bonded to the geonet with a hot knife application, allowing for high bond strength without the reduction of transmissivity values of other processes.
This 3D composite drainage network core products consist of centralized middle HDPE ribs that provide channelized flow, and diagonally placed top and bottom strands that minimize geotextile intrusion. The void maintaining core structure provides higher transmissivity than bi-planar products. Nonwoven geotextile is designed to provide drainage filtration to keep silt and soil particles from clogging the flow or to increase the friction characteristics.
The geonet core has two structures. Here, this structure is tri-axial structure as showed the picture below:
