Three-Dimensional Composite Drainage Network For Filtration Drainage And Protection

Product Introduction

Three-dimensional composite drainage network is a new type of geosynthetic material with unique three-layer structure and multiple functions. It is mainly made of high density polyethylene (HDPE) and processed by a special extrusion molding process.

Product Property

Filtration: Geotextiles can prevent soil particles from entering the drainage system to ensure smooth drainage channels.
Drainage function: the middle bar structure provides good water conductivity, so that water can be smoothly discharged.
Protection: The geomesh not only plays a drainage role, but also protects the integrity of the drainage system.

Product Application

1. Landfill: Used to collect and discharge leachate while controlling gas emissions.
2. Road construction: Instead of the traditional sand and gravel layer, it is used for drainage of roadbed and inner wall.
3. Pumped storage power station: used for seepage prevention and drainage at the bottom of the reservoir to enhance the support capacity of the foundation.
4. Other applications: including railway subgrade drainage, tunnel culvert drainage, retaining wall drainage and so on.
