Four Jobs This Liner Does Best
Most environmental orders come from these four sites. Each one stresses the liner in a different way.
Landfill Lining & Capping
Base liners and final caps for municipal and hazardous waste cells. A 2.0 mm smooth or double-textured HDPE liner meets the EPA Subtitle D benchmark for MSW landfills.
Spill barriers for tank farms and chemical storage areas. HDPE resists hydrocarbons and gives inspection crews a surface that is easy to walk, weld and test.

150,000 m²Southeast Asia
Municipal Landfill Expansion
2.0 mm (80 mil) HDPE for a Phase III cell expansion, with third-party seam testing witnessed across the full installation.
200,000 m²Mining Project
1.5 mm Smooth HDPE
Supplied for a tailings storage facility lining program, container-planned and shipped with batch test reports.

Copper Mine Heap Leach Pad
1.5 mm (60 mil) textured HDPE with a 600 g/m² geotextile cushion, specified for high ore loads and severe chemical exposure. The operator reports leach efficiency up 12.4% after relining.
LLDPE + GCLNorth America
Ash Pond Closure
A multi-layer capping system engineered to keep rainwater out of the closed pond — flexible LLDPE over a self-sealing clay liner.
How the Rolls Arrive
A liner that leaves the factory perfect but arrives creased is worthless. Packing is part of the product.

What thickness of HDPE geomembrane does a landfill liner need?
Most municipal landfill base liners use 1.5 to 2.0 mm HDPE. EPA Subtitle D sets 1.5 mm (60 mil) as the benchmark for MSW landfills, and many national standards follow it. The final grade depends on waste loads, slope design and local regulation — send us the project specification and we confirm the thickness against GRI-GM13 property tables.
Should I choose smooth or textured HDPE for slope work?
Use textured on side slopes. The roughened surface raises the interface friction angle up to 30 degrees and keeps cover soil from sliding; standard asperity height is 0.25 mm or more, with 0.40 mm available on request. Smooth HDPE costs less and works well on flat bases, pond floors and tank-farm pads.
Does Jinseed install the liner on site?
We are the manufacturer, so welding is done by your installation contractor or a local crew. Every order ships with a written installation guide covering subgrade preparation, hot-wedge welding, anchor trenches and seam testing, and our engineers support the QA plan remotely throughout the job.
What is the minimum order for a first project?
Trial orders start from 1 to 3 tonnes, enough for a test pad or a small pond. Production orders are planned by container, and a 20GP unit is the most economical way to ship standard rolls. Stock thicknesses move faster than custom specifications.
How can I verify liner quality before the container ships?
Ask for the batch Certificate of Analysis. Every production lot is sampled and tested in our in-house laboratory for thickness, tensile strength, carbon black content and oxidative induction time. You can also nominate BTTG or TRI Environmental to witness sampling before loading.
How long does production and delivery take?
Standard specifications need 7 to 15 days of production; custom widths, surfaces or colors need 15 to 25 days. We plan 20GP and 40HQ container loading as part of the quotation, and every shipment includes a loading report with photos and seal numbers.
Can you match a tender specification?
Yes — send us the spec sheet. We check every value against the GRI-GM13 property table, tell you which grade meets it, and produce to the tender numbers. If a value in the tender looks unusual for the application, we say so before you order.
What documents come with the shipment?
Every container ships with the batch Certificate of Analysis, the packing list, a loading report with photos and seal numbers, and the installation guide. Third-party test reports from BTTG or TRI Environmental can be arranged before loading.
