In civil, environmental, and mining projects where the ground subgrade is uneven, soft, or prone to significant differential settlements, rigid lining materials can stretch beyond their limits and fail. SherkatTrade is a leading supplier of LLDPE (Linear Low-Density Polyethylene) Geomembrane rolls, engineered specifically to handle high physical stress and complex geometries. Formulated from premium virgin linear low-density polyethylene resins, our LLDPE liners deliver superior multi-axial elongation, high flexibility, and outstanding stress-crack resistance, creating an absolute watertight seal on challenging substrates.
Distributed directly from the prominent industrial hubs of Isfahan, our LLDPE geomembranes are treated with high-grade carbon black and advanced UV stabilizers, guaranteeing a service life exceeding 50 years even under continuous exposure.
Sourced from certified manufacturers for maximum flexibility and elongation:
Many subgrades experience localized sinking or swelling due to soil shifting or high moisture. LLDPE geomembranes stretch and yield easily with these shifts, keeping the waterproof containment intact where rigid HDPE might crack.
Lining structural concrete tanks, vertical retaining walls, and tight 90-degree corners requires a soft, highly conforming material. LLDPE sheets wrap tightly around complex shapes and welded securely for absolute sealing.
Whether used as a buried barrier in building foundations and tunnels or left exposed to desert sun on landfill caps, our LLDPE geomembranes resist biological breakdown, root penetration, and chemical aging for decades.
| Physical Property | LLDPE Geomembrane (Linear Low Density) | HDPE Geomembrane (High Density) |
|---|---|---|
| Flexibility & Pliability | Excellent (Highly conforming to corners and complex shapes) | Moderate to rigid (Ideal for large flat earthen reservoirs) |
| Stress-Crack Resistance (ESCR) | Extremely high and superior | Standard compliance |
| Elongation capacity | Very High (>700% elongation at break) | High (Stiffer with lower strain tolerance) |
| Best Applications | Foundation waterproofing, landfill caps, geometric concrete ponds, tunnels | Large agricultural reservoirs, mining heap leach pads, deep dams |
All LLDPE geomembrane rolls supplied by SherkatTrade are tested in certified laboratories according to international GM17 standards:
LLDPE is the ideal choice when your project involves highly uneven terrains, high risk of ground settling, vertical walls, tunnels, or complex concrete pools with tight corners requiring a soft, easily welded material.
Yes. The premium LLDPE rolls supplied by SherkatTrade contain standardized carbon black (2.5%) and active HALS UV blockers, ensuring identical UV stability and lifespan.
LLDPE is welded using standard automatic double-wedge hot fusion welding machines for the main runs, and extrusion welding guns for detailed hand-welded corners and pipe penetrations.
Complex, engineered containment projects require highly adaptable and verified materials. SherkatTrade LLDPE geomembranes are the smart choice for challenging containment tasks. Daily roll shipping from Isfahan.
