Nonwoven Geotextile

Production Introduction

 

Non-woven Geotextile can be divided into Continuous Filament Needle punched non-woven Geotextile and Short Fibers Needle Punched Geotextile made from Polyester, formed by the process of needle punching and thermally bounding, offers optimum performance per unit weight. Non-woven Geotextile provides effective and economical solution of separation, filtration, drainage, protection and reinforcement functions for engineering projects.

 

Filtration

When water passes from a fine-grained to a coarse grained layer, Non-woven Geotextiles can retain fine particles well. Such as when water flows from a sandy soil into a Geotextile wrapped gravel drain.

 

Separation

Separate two layers of soil with different physical properties, such as the separation of road gravel from soft sub-base materials.

 

Drainage

Drain liquid or gas from the plane of the fabric, which leads to draining or venting of the soil, such as the gas vent layer in a landfill cap.

 

Reinforcement

Improve the load bearing capacity of a specific soil structure, such as the reinforcement of a retaining wall.
