LLDPE Geomembrane Manufacturer

Megaplast manufactures GRI-GM17 compliant LLDPE geomembranes, also known as LLDPE liners, designed for high flexibility, superior elongation, and stress crack resistance. They adapt to uneven, shifting, and settling ground conditions while maintaining reliable sealing performance. Ideal for pond liners, canal lining, landfill liners, and other containment applications.

Engineered for every site, built for every stress

Product info

Megaplast LLDPE liners are manufactured from high-quality LLDPE resin, providing excellent flexibility, elongation, and stress crack resistance. Designed for mining, landfill, and water containment applications, they adapt to ground movement while maintaining reliable sealing performance. Textured variants provide enhanced grip for slopes and heap leach pads.

Seepage barrier

Acts as a reliable seepage and vapour barrier, preventing water, gas, and other fluids from migrating through the ground.

Chemical resistance

Provides excellent resistance against chemical exposure, UV radiation, and environmental conditions for long-term performance.

Puncture resistance

Offers high durability and resistance against tears, punctures, and damage caused by sharp stones, ground movement, or rough handling.

Barrier — blocks radon and methane beneath structures
Variants

Available in smooth, single-side textured, and double-side textured variants to suit different installation and application requirements.

Exceptional flexibility

Rubber-like flexibility enables the liner to withstand folding, complex bends, and ground movement while maintaining performance

Superior resistance

Highly resistant to UV rays, chemical exposure, oxidation, thermal changes, and punctures — ideal for exposed and demanding applications

Easy installation

Panels can be fabricated and folded for easy transport and fast deployment; compatible with tape, extrusion, and wedge welding, depending on thickness and project requirements

Long-term durability

Maintains mechanical strength and integrity across a wide range of temperatures and weather conditions

Customizable &
cost-efficient

Available in multiple thicknesses and roll sizes for tailored solutions with lower installation and maintenance costs


1. What is LLDPE geomembrane, and when should you choose it over HDPE?

LLDPE (Linear Low-Density Polyethylene) geomembrane is a flexible, high-performance liner designed to adapt to uneven, shifting, and settlement-prone ground conditions. Compared to HDPE geomembranes, LLDPE offers higher flexibility, elongation, and stress crack resistance, making it the preferred choice for applications where the liner must conform to irregular surfaces without compromising containment performance.
