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.

Single-Sided Textured Geomembrane

Extra interface friction on one face while the other stays smooth for welding and contact layers. Used on slopes, covers and composite liner systems.

Double-Sided Textured Geomembrane

Textured surfaces on both faces for specified multi-layer containment systems. Select the grade using project-specific interface testing and slope-stability assessment; texture alone does not establish a safe slope.

LLDPE Geomembrane

Softer and more flexible than HDPE — it follows irregular shapes and settlement areas without stress. LLDPE rolls are available in 1.0–3.0 mm thicknesses for project requirements.

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.

Geomembrane rolls secured with lifting straps in the factory

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 documented seam acceptance requirements. 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.

For US project submittals, include the specification and required edition, acceptance values, thickness in mil or mm, roll dimensions, quantity and delivery location. Ask for documents for the proposed grade rather than assuming a general brochure proves project compliance.

No forms, no waiting for a sales rep to "check with the factory". You write to the factory.

Tell us the job

Application, thickness, surface type, quantity and destination port. A rough drawing is enough.

We confirm the fit

Questions Buyers Usually Ask

How do mil and millimeters compare in an HDPE geomembrane specification?

One mil equals 0.0254 mm. A 60 mil liner is 1.524 mm, and an 80 mil liner is 2.032 mm. Rounded metric labels are not exact substitutes for a specified nominal thickness. Send the required thickness, tolerance, surface finish and test requirements with your RFQ so the proposed grade can be checked against your project specification.

How do I choose between smooth and textured HDPE?

Select the surface against the approved liner-system design. Where slope stability matters, assess interface shear behavior using the actual adjacent materials and project conditions. Send the drawings and specified test criteria with your enquiry; texture alone does not guarantee stability.

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 40HQ 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.
