One of India’s leading manufacturers of GRI-GM17-compliant flexible geomembranes,
offering 7-layer technology for superior chemical resistance, UV stability, and durability in critical containment projects.
Megaplast’s flexible geomembranes are made from specialized LLDPE polymers with low crystallinity, designed to excel in multi-axial stress and dynamic environments.
Provides waterproof containment in irregular surfaces and contours
Used in ponds, lagoons, canals, and reservoirs
Applied in landfill capping and leachate containment
Suitable for mining, aquaculture, and environmental protection projects
Acts as a flexible containment barrier in dynamic soil or substrate conditions
Superior flexibility and elongation for folding and bending without damage
Excellent puncture and tear resistance
UV and chemical resistant – suitable for exposed applications
Flexible Geomembrane is a high-performance polyethylene liner engineered for superior pliability and multi-axial elongation. Unlike standard HDPE (High-Density Polyethylene), which is rigid and best suited for flat surfaces, flexible geomembranes (typically LLDPE-based) are designed to conform to irregular terrain and withstand dynamic loads. Megaplast’s flexible liners utilize an advanced 7-layer blown film construction, providing significantly higher resistance to stress cracking and puncture compared to traditional mono-layer HDPE.
Feature | Standard HDPE | Megaplast Flexible Geomembrane |
Pliability | Low (Rigid) | High (Flexible) |
Construction | Mono or 3-Layer | Advanced 7-Layer Blown Film |
Terrain Suitability | Flat/Prepared Substrates | Irregular/Dynamic Substrates |
Primary Standard | GRI-GM13 | GRI-GM17 |
Megaplast utilizes world-class 7-layer co-extrusion blown film technology (powered by Bandera), making us one of the few global manufacturers with this capability. This 7-layer machine allows us to customize each layer for specific performance traits—such as enhanced UV stabilization, superior chemical barrier properties, and optimized mechanical strength. This results in a more durable and reliable containment solution than conventional 3-layer or mono-layer alternatives.
Yes. Quality and compliance are central to our operations. Megaplast Flexible Geomembranes are manufactured in our GAI-LAP and NABL-accredited Innovation Centre, ensuring they meet or exceed GRI-GM13 (HDPE) and GRI-GM17 (LLDPE) international specifications. Our facility is also EU CE certified by SKZ Germany and holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, guaranteeing global reliability for critical infrastructure.
