Description：
Short fiber Non woven geotextile is a new type of construction material used in civil engineering. It is made of PP or PET fibers by needle punched processes. The tensile strength of PP non woven geotextile is higher than PET non woven. But both of them has a good tear resistance and also has a good main function: filter, drainage and reinforcement. Specifications range from 100 grams per square meter to 800 grams per square meter.
Product Features：
It is an environmentally friendly building material.
Good mechanical properties, good water permeability, corrosion resistance and aging resistance.
Strong anti-burial and anti-corrosion performance, fluffy structure and good drainage performance.
Good friction coefficient and tensile strength, and has geotechnical reinforcement performance.
Good overall continuity, light weight and convenient construction.
It is a pervious material, so it has good filtering and isolation function and strong puncture resistance,so it has good protection performance.
