Premium PET Filament Geotextiles — Direct from the Manufacturer
MJY brand filament polyester geotextile is the kind of continuous filament needle punched non–woven geotextile made from polyester virgin material, formed by the process of needle punching and thermally bonding. Our filament polyester geotextile offers optimum performance per unit weight which features good mechanical properties of tensile strength and puncture resistance, good drainage ability, acid and alkali resistance and anti-aging. Filament geotextile is widely used for separation, filtration, drainage, protection and subgrade reinforcement functions for civil engineering projects.

FAQ
What is Filament Polyester Geotextile?
A continuous filament PET nonwoven geotextile, needle-punched and heat-set for high strength, low elongation, and durable filtration/separation.
PET vs PP—what should I choose?
PET offers higher modulus and lower creep for long-term reinforcement; PP is lighter and chemically inert for broader drainage/separation tasks.
How do I size AOS and permittivity?
Match AOS to soil gradation (retain fines, allow flow). Select permittivity to meet design hydraulic gradient. We’ll size it from your sieve curve.
What overlaps should I use?
Typically 300–600 mm overlap; increase on very soft subgrades or high flows. Follow project spec/engineer’s direction.
Do you offer wholesale and OEM?
Yes—wholesale/factory price, private label, custom GSM/width/color, and distributor terms. Buy direct from MJY factory.
