High Quality for Geotextile-Geomembrane - Composite Drainage Network – Yingfan Detail:
Product Description
Shanghai Yingfan Engineering Material Co., Ltd. is a composite drainage network and other earth work products supplier, located in Shanghai China. Man of our clients are large-scale enterprises, which are among Fortune Global 500 or listed companies, such as PetroChina, Sinopec, Yili group, Wanke group, Mengniu group, and so forth. And we have won a lot of small or huge biding related with geosynthetic usage programs in our country. Composite drainage netwok is our top sales product in our supply chain.
Composite Drainage Network Introduction
A Composite Drainage Network ( Geocomposite Drainage Liners ) is a new type of dewatering geotechnical material, which is designed to complement or replace sand, stone and gravel. It consists of a HDPE geonet heat-bonded with one side or both sides of nonwoven needle punched geotextile.
The geonet has two structures. One structure is bi-axial structure and the other is tri-axial structure.
Bi-axial structure / Tri-axial structure

geotextile and drainage network
Its performance can meet or exceed our national standard GB/T17690.
Composite Drainage Network: how to work
| Composite Drainage Network | Network core | 1. Centralized middle HDPE strands provide channelized flow |
| 2. Upper and bottom fillet form support to avoid geotextile inserting into dewatering channel | ||
| Geotextile | one sided or double sided adhesive seepage geotextiles form a “filtration – drainage – ventilation – protection” overall performance |

FAQ
Q1: Can I get a sample from your company?
A1: Yes. We can provide free available sample. For special request sample, cost can be negotiated.
Q2: What is your minimum order quantity of your product?
A2: 1000m2 is for available stock of composite drainage network. But for short stock of our ordinary products, MOQ is 5000m2.
Q3: Which is your port of delivery of goods?
A3: Usually it is Shanghai port because our company is located here. But if you want to delivery goods from other ports of China, we can help to arrange.
Drainage is a critical factor when designing a civil engineering project. Dozens of years ago, we usually use the natural drain aggregate such as sand, gravel to drainage liquid appearing in such project. As per the polymer synthetic material development, more and more synthetic products are created and used to directly replace or be combined with those traditional aggregate because of their features of good performance, low cost and easy installation.
