Key Benefits
- 100% Anti-Seepage: With a permeability coefficient of ≤1.0×10^-13 g.cm/(cm².s), our liners ensure zero water loss for your reservoir or dam.
- Heavy Duty Durability: Specifically designed to resist punctures and tears. Our 60 mil (1.5mm) liners are ideal for rocky terrains and deep landfills.
- UV & Weather Resistant: Contains 2-3% Carbon Black to resist UV degradation, making it perfect for exposed applications like farm ponds and solar evaporation ponds.
- Chemical Resistance: Safe for use in mining (heap leach pads), sewage treatment, and industrial waste containment.
- Fish & Shrimp Safe: Non-toxic, food-grade material suitable for aquaculture (fish farming/shrimp ponds).
Application Scenarios
- Agricultural Water Reservoirs: Prevent water loss in irrigation pools. Recommended: 0.5mm – 0.75mm (20-30 mil).
- Aquaculture (Fish/Shrimp Ponds): Smooth surface prevents bacteria buildup and allows for easy cleaning. Recommended: 0.5mm – 1.0mm (20-40 mil).
- Dam & Canal Liners: Large-scale waterproofing for earthen dams. Recommended: 1.5mm – 2.0mm (60-80 mil).
- Landfills & Mining: High-strength containment for hazardous waste. Recommended: 1.5mm+ (60 mil+).
Water Reservoirs Case
Comparison: LLDPE vs. HDPE
- HDPE (High Density): Stiffer, stronger, better UV resistance. Best for large open reservoirs and simple shapes.
- LLDPE (Linear Low Density): More flexible. Best for uneven terrain or small tanks with complex corners.

FAQ
- Q: What is the price of a 60 mil HDPE liner?
- A: Prices vary based on raw material costs (resin) and order quantity. As a factory, we offer wholesale pricing. Contact us for a quote per square meter/foot.
- Q: Do you sell geomembrane welding machines?
- A: Yes, we supply hot wedge welders and extrusion hand welders compatible with our liners. We also provide installation guides.
- Q: What is the difference between 30 mil and 60 mil liners?
- A: 30 mil (0.75mm) is lighter and easier to handle, suitable for small ponds. 60 mil (1.5mm) is heavy-duty, used for large reservoirs, landfills, and projects requiring high puncture resistance.
- Q: Do you ship to Kenya, India or USA?
- A: Yes, we have extensive experience exporting to the USA, Africa, Southeast Asia, and South America. We handle shipping and logistics.
