Product Description

Introduction

Composite drainage net is in two or three dimensional drainage geosynthetic products,consist of a geonet core,with heat-bonded nonwoven geotextile on both sides.The geonet is manufactured from high density polyethylene resin,in trixial structure.The nonwoven geotextile can be polyester staple fiber or long fiber nonwoven geotextile or polypropylen staple fiber nonwoven geotextile.

Composite drainage net is a drainage system with excellent performance, widely used in urban roads, car parks, parks, squares and other places.

Applications

Lowering groundwater level: Composite drainage networks can be used to lower the groundwater level, effectively controlling the groundwater level through functions such as water absorption, diversion, and drainage, and preventing the rise of groundwater level from affecting the engineering structure.
Preventing soil erosion: In land engineering, composite drainage networks can be used to prevent soil erosion and slope erosion, protect the foundation soil from erosion, and maintain surface stability.
Greening engineering: Composite drainage networks can also be used as soil improvement materials in greening engineering, providing sufficient air, water, and nutrient supply, promoting plant growth, and improving the green environment.
Road engineering: In road engineering, composite drainage networks can be used for the reinforcement and drainage of road base and roadbed, improving the bearing capacity and water resistance stability of the road.

In summary, composite drainage networks have a wide range of applications in fields such as land engineering, water conservancy engineering, greening engineering, road engineering, etc. They can play functions such as drainage, anti-seepage, and soil protection, improving the reliability and stability of engineering.
