Smooth HDPE geomembrane rolls stacked for shipment

Smooth HDPE Geomembrane

For flat or gently sloped containment areas where easy welding, fast inspection and a reliable hydraulic barrier matter most. Ponds, reservoirs, wastewater lagoons and secondary containment.

Double-Sided Textured Geomembrane

Friction on both faces for demanding slope stability and multi-layer containment systems. Standard choice for landfills, mining facilities and steep containment slopes.

LLDPE Geomembrane

Softer and more flexible than HDPE — it follows irregular shapes and settlement areas without stress. Food-grade 0.5 and 0.75 mm rolls are the standard choice for aquaculture ponds.

Sized for Big Projects

Our own 55,000 m² plant in Zhaoqing High-tech Industrial Development Zone runs automated lines around the clock — so a 40-container order does not push your project into next season.

How We Keep Every Roll Consistent

A liner fails where the sheet is weakest, so consistency matters more than any single test number. Four controls run through the whole production.

Virgin resin only

Geomembrane-grade HDPE from Sabic, Chevron Phillips and Borealis. No recycled content — and a certificate of analysis for every resin batch.

Flat-die extrusion

German flat-die and calendering line with controlled cooling keeps thickness uniform across the full 8.0 m width, roll after roll.

Inline inspection

Laser thickness monitoring and spark pinhole detection run continuously while the sheet moves — not just at the start and end of a batch.

Roll traceability

Production and test records tie back to the roll numbers on your packing list, so your project file stays audit-ready years later.

What the Standard Asks vs What We Test At

GRI GM13 is the reference most specifications are written around. Here is the requirement next to our reported results, side by side.

Recent Projects Using Our Liners

Three jobs, three different problems. Each one started the same way — the buyer sent a spec and asked what we would recommend.

Mining · Chile

Copper heap leach pad, 1.5 mm textured + geotextile cushion

The ore loads were punching through the old liner. We supplied double-sided textured HDPE with a 600 g/m² PET cushion underneath, matched to the client's slope and chemical exposure. Once seepage was eliminated, leaching efficiency rose.

Landfill · Southeast Asia

Municipal landfill expansion, 2.0 mm smooth HDPE

A municipal operator needed a base liner with a 50-year design life and seams tested to ASTM D6693. We produced 2.0 mm smooth rolls at 8.0 m width to cut the seam count, with batch documentation for the environmental review.

Aquaculture · Indonesia & Vietnam

Intensive shrimp ponds, 0.5 / 0.75 mm food-grade LLDPE

Farms replacing aging lined ponds chose flexible food-grade LLDPE that conforms to pond shapes and cleans down fast between cycles. Farm records showed survival rates climbing once seepage and soil contact were under control.

Questions Buyers Usually Ask

How do I choose between smooth and textured HDPE?

Use smooth on flat or gentle areas — it welds and tests easily. Use textured on slopes where the liner must grip the soil or the layers above and below it. Send us your slope details and we will confirm which surface fits.

Which resin do you use?

Virgin geomembrane-grade HDPE from Sabic, Chevron Phillips and Borealis. Every resin batch comes with a certificate of analysis, and we share it with your order.

Can I get test reports for my actual order?

Yes. Each production batch is tested in our own lab, and TRI Environmental independently tests against applicable GRI GM13 requirements. BTTG sampling can be arranged on request.

How long does an HDPE liner last?

Buried and correctly installed, HDPE geomembrane is generally rated for a service life of 50 years or more. Warranty terms run from 10 to 20 years depending on the product and application.

What is your minimum order and lead time?

Trial orders start from 1 to 3 tonnes, and a 20GP container is the most economical starting point. Standard production takes 7 to 15 days; custom thicknesses or roll sizes take 15 to 25 days.

Do you help with installation?

Every order ships with an installation and welding guide, welding parameters for your thickness, and seam testing instructions with acceptance criteria. Tell us your crew's experience level and we will adjust the guidance.
