LLDPE Geomembrane Pond Liner 500 micron Price
LLDPE (linear low-density polyethylene) Geomembrane Pond Liner is a widely used anti-seepage material in water tanks, dams, and other bodies of water, with a thickness of 500 microns. This material has excellent flexibility and durability, and can effectively resist the effects of ultraviolet radiation, chemicals, and temperature changes. The production process of LLDPE geomembrane pond liner ensures its uniform thickness and high strength, enabling it to maintain good performance under various environmental conditions. In addition, the low permeability of LLDPE geomembrane pond liner can effectively prevent water loss, ensure water quality and quantity, and is widely used in fields such as agricultural irrigation, environmental engineering, and water resource management. It is easy to install and has low maintenance costs, making it an important choice for modern water management.
Linear Low-Density Polyethylene (LLDPE) geomembrane pond liners are widely used in environmental containment projects due to their flexibility, chemical resistance, and cost-effectiveness. The 500 micron LLDPE geomembrane variant is particularly favored for medium to large-scale ponds, irrigation systems, mining tailings, and aquaculture applications. This article offers a technical breakdown of the pricing structure of 500 micron LLDPE geomembrane pond liners, including influencing factors, applicable standards, and important considerations.
What Is a 500 Micron LLDPE Geomembrane Pond Liner?
A 500 micron LLDPE liner is a geomembrane sheet with a thickness of 0.5 mm, engineered to offer a balance between durability and cost. It is primarily used for lining ponds, canals, waste storage, and other fluid containment areas.
Key Characteristics:
Material: Linear Low-Density Polyethylene
Thickness: 0.5 mm (500 microns)
Tensile Strength: ≥16 MPa
Elongation at Break: ≥600%
Puncture Resistance: High due to molecular flexibility

FAQs on 500 Micron LLDPE Geomembrane Liners
Q1: Is 500 micron LLDPE suitable for fish ponds?
A: Yes, provided the material is food-grade and free from toxic additives. UV-stabilized variants are preferred for outdoor exposure.
Q2: Can 500 micron liners be used for hazardous waste?
A: No. For hazardous applications, thicker geomembranes (e.g., 1.5 mm HDPE) are required under EPA guidelines.
Q3: How long does a 500 micron LLDPE liner last?
A: In buried conditions, up to 20 years. In exposed environments, lifespan drops to 5–10 years without UV stabilization.
Q4: What is the difference between LLDPE and HDPE liners?
A: LLDPE is more flexible and has better elongation, making it suitable for uneven substrates. HDPE is more rigid and chemically resistant.
Q5: Can it be repaired on-site?
A: Yes, using hot-air or extrusion welding equipment, though professional repair is advised to maintain waterproof integrity.
Installation Tips
Store the liner in shaded conditions before use to avoid premature UV degradation.
Ensure surface is free of sharp objects, debris, and vegetation.
Allow for thermal expansion during welding (especially in hot climates).
Use a minimum overlap of 10 cm for seaming.
Avoid installation during windy or rainy conditions.
Final Thoughts and Professional Recommendation
The 500 micron LLDPE geomembrane pond liner represents a cost-effective solution for a range of water containment projects. While pricing varies based on location, volume, and quality specifications, the liner remains an accessible and flexible choice for agriculture, aquaculture, and municipal water storage applications.
For project planners, engineers, or procurement specialists, careful attention to material standards, certification, and installation methodology is critical to ensuring the long-term success of any geomembrane deployment.
