Product Description

Hanovo PET Non-woven Geotextile is continuous filament needle punched non-woven 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.

Applications Of Nonwoven Geotextile

1. 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.

2. Separation

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

3. Drainage 

To 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.

4. Reinforcement 

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