ANVIX^™ LLDPE Geomembrane

Technical Highlights

Superior Flexibility

Adapts easily to uneven, curved and irregular surfaces, reducing installation stress and material strain. Ideal for areas subject to settlement or ground movement.

High Elongation Performance

Excellent stretchability before failure helps absorb movement without cracking, improving long-term structural reliability.

Enhanced Puncture Resistance

Better resistance against stones and uneven subgrades reduces the risk of installation damage, suitable for aquaculture and earthwork applications.

Chemical Resistance

Resistant to acids, alkalis, salts and industrial chemicals, suitable for wastewater and containment systems while maintaining performance in aggressive environments.

UV Stabilised

Carbon black and UV stabilisers protect against sunlight degradation, suitable for long-term outdoor exposure and extended service life.

Easy Installation

More flexible than HDPE geomembranes, offering easier handling, field deployment and better conformity to site conditions.

Why Choose LLDPE Geomembrane?

Better Flexibility Than HDPE

LLDPE geomembrane provides significantly higher flexibility and elongation, allowing the membrane to conform to uneven terrain and complex site conditions.

Improved Puncture Resistance

The flexible molecular structure helps absorb impact and reduces the risk of puncture damage during installation.

Superior Stress Crack Resistance

LLDPE performs exceptionally well in applications where long-term movement and deformation may occur.

Reliable Long-Term Containment

Combined with UV stabilisers and antioxidant packages, LLDPE geomembrane delivers durable waterproofing performance for demanding containment applications.

Quality Assurance

Standards & Testing

ANVIX^™ LLDPE Geomembrane is manufactured and tested in accordance with internationally recognised geosynthetic standards, ensuring consistent quality and reliable field performance.

GRI GM17

Geosynthetic Research Institute Specification

GM17 is the industry-recognised specification for LLDPE geomembranes, covering minimum requirements for thickness, tensile properties, tear resistance, puncture resistance and carbon black content.

ASTM

ASTM Test Methods

Material properties are evaluated using established ASTM test methods, including tensile properties, tear resistance, puncture resistance, density and dimensional stability.

QA / QC

Quality Control Procedures

Each production batch is monitored for thickness uniformity, surface quality and mechanical properties to ensure consistent compliance with specification.

UV / OIT

Oxidative Induction Time Testing

OIT testing verifies the effectiveness of antioxidant packages, supporting long-term durability claims for outdoor installations.
