Geotextile Manufacturer
We make needle-punched PET geotextile in our own factory in Guangdong, China — 100 to 830 g/m², rolls up to 6 m wide, every batch tested before it ships. You buy from the factory, not from a trader.
Long polyester threads are laid into a loose web, then thousands of needles punch through it and lock the threads together. No glue, no weaving. Water passes through the fabric, but soil stays behind it.




Properties from our PET non-woven geotextile data sheet, with ASTM test methods listed in the PDF. Tensile, grab tensile and tear strength below are shown in the machine direction (MD).

For liner protection, puncture is the number most buyers watch first: at 600 g/m² the fabric holds back 7,500 N. Values for 12 grades from 125 to 800 g/m², including MD and TD properties, are in the data sheet.Download the data sheet
The weight groups below are starting points for discussion, not universal design classes. Check the specified polymer, strength, puncture resistance and hydraulic properties. Soil conditions, loading and construction requirements can change the suitable grade.
French drains, the back of retaining walls, drainage under sports fields and parking lots.
A separation layer between subgrade and aggregate. Select and install the grade against the design and construction requirements; the fabric does not replace a designed pavement base.
Sits above or below a geomembrane in landfills and reservoirs, taking the pressure from sharp stones so the liner stays intact.

Send the application, specified polymer, required test methods and values, fabric weight, roll size, quantity and destination. Include soil or liner-interface information and the required delivery date so the proposed grade can be checked against the project.

55,000 m² in the Zhaoqing High-tech Industrial Development Zone, Guangdong. Resin comes in, finished rolls go out — nothing is outsourced.

Samples from every batch are pulled and tested for strength, puncture and water flow. No passed test, no shipment.

A retained sample is stored for every batch. Years later, any roll can still be traced back and re-tested.
Not sure which polymer your soil needs? Tell us the pH and the load, and we will say which one fits — and why.

Keeps the gravel base separate from soft subgrade so the road carries traffic longer.

The ore is sharp and the slopes are steep. The fabric went under the textured liner as a cushion and took the point loads. With leaks eliminated, the mine's leaching efficiency rose by 12.4%.
How cushion installation works
With fine soil kept out of the gravel base, drainage keeps working and the base stays at design thickness. Long-term pavement records show roads built this way last 15–18 years instead of 10–12.

A 40HQ takes about 38–39 rolls — roughly 50,000 m² of 200 g/m² fabric, or about 17,000 m² of 600 g/m². We plan the roll sizes around your project before production.
Rolls are wound on reinforced cores and secured with lifting straps at both ends.
You get loading photos, structural checks and container seal numbers before the truck leaves the factory.

Our quality system covers geotextile and geomembrane production and is audited on a regular cycle.
Corporate membership of the International Geosynthetics Society is separate from product certification and project approval. Request the applicable test reports and technical documents for the proposed grade.
Our in-house test methods are accredited against third-party laboratory practice, so batch results hold up when your engineer re-checks them.
BTTG or TRI Environmental can sample and seal your goods before loading — you nominate, we arrange.
One oz/yd² is approximately 33.906 g/m². For example, 4 oz/yd² is about 135.6 g/m² and 8 oz/yd² is about 271.2 g/m². These are unit conversions, not a statement that a particular production grade is available or equivalent. Weight alone does not establish suitability: send the required polymer, test methods, strength, puncture and hydraulic criteria so the proposed PET grade can be checked against your project specification.
PET and PP are different polymers, and performance depends on the product grade and exposure. Compare the specified strength, hydraulic properties and durability evidence for the actual conditions. This PET non-woven product is offered for separation, filtration and protection; it must not be substituted for specified structural reinforcement without design approval.
Start with the required function and project acceptance criteria. For filtration, check soil retention and water-flow requirements; for separation, check construction survivability and the specified mechanical properties; for liner protection, evaluate the actual liner, adjacent materials and loading. Fabric weight alone does not establish suitability.
Every order ships with a Manufacturer's Quality Certificate showing the batch results for grab tensile (ASTM D4632), CBR puncture (ASTM D6241) and permittivity (ASTM D4491). If your project needs it, BTTG or TRI Environmental can sample and seal the goods before loading.
Widths go up to 6 meters. Roll length depends on the weight — for example about 220 m per roll at 200 g/m² and about 75 m at 600 g/m². We can plan roll sizes around your layout to cut field seams.
A 40HQ container takes about 38–39 rolls, roughly 10.5 tons. That works out to about 50,000 m² of 200 g/m² fabric, or about 17,000 m² of 600 g/m².
The fabric has UV stabilizers and keeps over 75% of its strength after 500 hours of test exposure, but it is made to be buried. Cover it with soil or aggregate within 48–72 hours of laying it out.
Trial orders start from 1–3 tons. Standard production takes 7–15 days after we confirm the specification and receive the deposit; custom orders take 15–25 days.

Send the project function, required polymer and test criteria, weight in g/m² or oz/yd², roll dimensions, quantity and delivery location. Attach the specification so the proposed PET grade, documentation and quotation can be compared on the same basis.
