Coef. Friction >30° Bi-directional TexturedDouble Color Geomembrane
HDPE liner manufactured with contrasting upper and lower colors, making scratches, punctures, and installation damage easier to identify during field inspection.
Contrasting Colors Easy Damage InspectionChoose the Right Liner Before You Buy
A geomembrane project should not start from price only. The right material depends on liquid type, subgrade condition, slope angle, UV exposure, expected service life, and installation method.
- HDPE geomembrane is the first choice for chemical resistance, landfill containment, mining leach pads, wastewater ponds, and long outdoor exposure.
- LLDPE geomembrane is better when the base surface has more settlement risk or the liner must handle higher elongation.
- Textured geomembrane is used on slopes, landfill sidewalls, heap leach pads, and projects that require higher interface friction.
- Geotextile protection layers reduce puncture risk when the soil base contains sharp particles or when aggregate drainage layers are used.
Match Thickness to Project Risk
Thickness should follow containment risk, site load, liner exposure, subgrade condition, and local project specification. Thin liners reduce cost, but under-designed liners increase puncture and repair risk.
| Application | Common Thickness Range | Key Design Concern |
|---|---|---|
| Aquaculture ponds | 0.5mm – 1.0mm | Water retention, easy cleaning, UV exposure |
| Irrigation reservoirs | 0.75mm – 1.5mm | Water pressure, slope protection, sunlight |
| Landfill lining | 1.5mm – 2.0mm | Leachate containment, puncture resistance, seam control |
| Mining leach pads | 1.5mm – 2.5mm | Chemical contact, heavy load, slope stability |
| Industrial wastewater ponds | 1.0mm – 2.0mm | Chemical compatibility, temperature, sludge cleaning |
| Secondary containment | 1.0mm – 2.0mm | Spill control, berm lining, emergency retention |
Smooth or Textured Geomembrane?
Surface selection directly affects installation efficiency, slope friction, anchoring, drainage layer contact, and long-term liner stability.
Smooth HDPE
Used for ponds, lagoons, reservoirs, landfill bases, and flat containment areas. It is easier to clean, inspect, weld, and handle on simple site layouts.
Single Textured
Used when one side needs higher friction against soil, geotextile, geonet, or drainage layers while the other side remains smoother for welding and installation.
Double Textured
Used on steep slopes, landfill sidewalls, heap leach pads, and high-risk interfaces where both sides require stronger friction performance.
Good Installation Starts Before Welding
Even a high-quality geomembrane can fail if the base is not prepared correctly. The installation plan should control soil compaction, sharp stones, wrinkles, weather, anchoring, welding temperature, and testing sequence.
- Prepare a smooth and compacted subgrade before liner deployment.
- Use geotextile cushioning when puncture risk is high.
- Lay rolls according to panel layout drawings to reduce unnecessary seams.
- Use hot wedge welding for long straight seams and extrusion welding for details, repairs, pipe penetrations, and corners.
- Protect the installed liner before drainage aggregate, soil cover, or concrete layers are added.
The Seam Is the Real Risk Point
In containment projects, the liner sheet itself is only one part of performance. Weld seams, pipe penetrations, corners, repairs, and anchor trenches must be controlled carefully because these areas carry higher leakage risk.
- Trial welding confirms temperature, speed, pressure, and weather suitability before site welding begins.
- Non-destructive tests help find air channel leakage, pinholes, weak extrusion welds, and unsealed patches.
- Destructive tests verify peel and shear strength so the weld can be accepted based on measurable evidence.
- All failed seam areas should be repaired, retested, and recorded before the liner is covered.

HDPE Geomembrane Questions Buyers Ask
These questions help purchasing teams, contractors, and project engineers check whether the product is suitable before requesting a quotation.
What thickness should I choose for a pond liner?
For small aquaculture and irrigation ponds, 0.5mm to 1.0mm is common. For reservoirs, wastewater ponds, landfill, and mining projects, thicker liners are usually required because load, chemical exposure, and puncture risk are higher.
When should I use textured HDPE geomembrane?
Textured HDPE is recommended for slopes, landfill sidewalls, heap leach pads, and interfaces where higher friction is needed. Smooth liner is easier to clean and is usually enough for flat pond or lagoon bottoms.
Can Jinseed provide test reports with each order?
Yes. Production and quality documents can be prepared according to the order requirement. Common checks include thickness, density, tensile strength, elongation, tear resistance, puncture resistance, carbon black, and OIT.
How are geomembrane rolls packed for export?
Rolls are normally packed with protective wrapping and loaded by container. Roll width, length, weight, and container loading quantity should be confirmed before production to reduce handling problems at the destination site.
Can I use geomembrane without geotextile?
It depends on the subgrade. If the base is smooth and free from sharp particles, a project may use geomembrane alone. If puncture risk is high, a non-woven geotextile protection layer is strongly recommended.
What information should I provide before requesting a quote?
Please share the application, project size, required thickness, surface type, roll width, site condition, destination port, and any drawing or specification. This helps our team recommend the right liner instead of quoting only by square meter.
How do I choose between HDPE and LLDPE geomembrane?
HDPE is usually selected for chemical resistance, outdoor exposure, landfill, mining, and wastewater containment. LLDPE is better when the liner needs more flexibility, higher elongation, or better fit on uneven subgrades.
Can geomembrane rolls be customized by size?
Yes. Roll width, roll length, thickness, surface finish, and color can be confirmed based on production capability and project requirements. Custom roll planning can reduce field seams, but it should also consider loading, lifting, and site handling limits.
What should be checked before installation starts?
The site team should check subgrade smoothness, sharp stones, anchor trench layout, panel direction, weather conditions, welding equipment, trial weld settings, and protection layers before large-area deployment begins.
