Introduction

PET Non Woven Geotextile is a made of high tenacity polyester fiber,needle-punched to form a dimensionally stable fiber network.It’s a type of fabric used in civil engineering and construction projects for soil stabilization, erosion control, and drainage etc.It’s available with width 1-6m and generally length 50-100m.

Advantages Of PET Non Woven Geotextile

 *Separation

Non woven geotextile as a separation layer.Separation function prevents mixing of the sub soil and aggregate.This in turn allow the non woven geotextile to uphold and enhance the integrity and functionality of the said soil.

*Filtration

Filtration function of non woven geotextile material allow continuous liquid flow through the geotextile layer while it prevents migration of fine soil particles across the layer.

*Reinforcement

Reinforcement is the function of the geotextile when incorporated in the soil structure imparts structural stability.

*Transmissivity

This function is also known as drainage function.This function facilitates planer flow of liquid or water along the geotextile material.

*Moisture Barrier

Non woven geotextile as a moisture barrier when impregnated with asphalt or other compounds. Especially in road constructions it is useful function for repairing cracked pavements.

*Stress Absorption

It’s also known as protection function.Geotextile products imparts this function in the pavement overlay.

 Application Of PET Non Woven Geotextile

*Road construction and repairs

*Paved runways

*Rail track stabilization

*Pavement overlays

*Landscaping and sports fields

*Drainage systems

*Pipe lining and foundation

*Canal,pond and reservoir lining

*Roofing systems

*Erosion control

*Coastal Protection

*Landfill system
