Product Description

Introduction

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

Composite drainage internet is a drainage device with notable performance, broadly used in city roads, auto parks, parks, squares and different places.

Applications

Lowering groundwater level: Composite drainage networks can be used to decrease the groundwater level, correctly controlling the groundwater stage via features such as water absorption, diversion, and drainage, and stopping the upward jab of groundwater degree from affecting the engineering structure.
Preventing soil erosion: In land engineering, composite drainage networks can be used to stop soil erosion and slope erosion, guard the basis soil from erosion, and preserve floor stability.
Greening engineering: Composite drainage networks can additionally be used as soil enchancment substances in greening engineering, supplying adequate air, water, and nutrient supply, promotion plant growth, and enhancing the inexperienced environment.
Road engineering: In street engineering, composite drainage networks can be used for the reinforcement and drainage of avenue base and roadbed, enhancing the bearing ability and water resistance balance of the road.

In summary, composite drainage networks have a vast vary of functions in fields such as land engineering, water conservancy engineering, greening engineering, avenue engineering, etc. They can play features such as drainage, anti-seepage, and soil protection, enhancing the reliability and steadiness of engineering.
