2.0mm (80 mil) Smooth LLDPE Geomembrane | Heavy-Duty Flexible Liner for Mining & Reservoirs

PRODUCT DETAILS
1. Product Overview
Extreme Durability Meets Ultimate Flexibility.
For projects that demand the physical toughness of a thick liner but cannot risk the stress cracking associated with rigid HDPE, our 2.0mm (80 mil) Smooth LLDPE Geomembrane is the singular solution.
This heavy-duty liner offers the same thickness and puncture resistance as standard mining liners but features a unique Linear Low-Density Polyethylene molecular structure. This allows it to absorb significant differential settlement and ground movement without rupturing, making it the safest choice for large-scale reservoirs, landfill caps, and mining containment on unstable subgrades.
2. Key Features
-
80 mil (2.0mm) Armor: The substantial thickness provides exceptional puncture resistance against sharp rocks and construction loads, reducing the need for expensive sand bedding compared to thinner liners.
-
Settlement Proof: With an elongation at break exceeding 800%, this liner acts like a tough elastic skin. It stretches to bridge voids caused by sinkholes or subsiding waste piles where rigid liners would fail.
-
Arctic Grade Flexibility: Engineered to remain pliable in extreme cold. It resists thermal contraction stress, making it ideal for projects in Canada, Russia, and high-altitude regions.
-
Easy Welding: The 2.0mm thickness provides ample material for a robust double-track hot wedge weld, ensuring high weld strength and easy air channel testing.
-
Chemical Resistance: While flexible, it maintains excellent resistance to brine, saltwater, and general industrial wastewater.
3. Detailed Application Scenarios
Large Earthen Reservoirs & Dams
In massive water storage projects, the sheer weight of the water can cause the ground to settle over time. A 2.0mm Smooth LLDPE Liner provides the structural integrity to hold millions of gallons of water while accommodating these geological shifts, preventing catastrophic leakage.
Mining & Oil Field Frack Ponds
For "Frack Ponds" or produced water pits in the oil and gas industry, liners are often exposed to rough handling and heavy equipment. The 80 mil thickness withstands mechanical abuse, while the LLDPE material prevents environmental stress cracking (ESCR) typical in exposed conditions.
Landfill Caps (Final Cover)
The top of a landfill is constantly moving as waste decomposes. A 2.0mm LLDPE liner is heavy enough to sit flat without wind uplift issues (ballast effect) and flexible enough to settle with the trash mountain for decades.
Remediation Pads
For temporary soil treatment pads where heavy trucks dump contaminated soil, the 2.0mm thickness is essential to prevent tires from shredding the liner, while the flexibility ensures it conforms to the berms and drainage sumps.

5. 2.0mm Comparison: LLDPE vs. HDPE
-
Q: When should I choose 2.0mm LLDPE over 2.0mm HDPE?
-
A: Choose 2.0mm LLDPE if your site has soft soil, potential for ground settlement, or requires a liner that is easy to fold and pre-fabricate.
-
A: Choose 2.0mm HDPE only if the ground is perfectly compacted (like concrete) and your primary concern is extreme chemical resistance (e.g., strong acids in hazardous waste).
