SAGEOS is proud to announce the addition of the GRI GM42 Specification to its portfolio of specialized testing services for high-density polyethylene (HDPE) geomembranes.

This new capability strengthens our position as a trusted partner to the geosynthetics industry by offering testing services that meet the most demanding international standards.

A Recognized Method for Predicting Long-Term Performance

Developed by the Geosynthetic Research Institute (GRI), the GRI GM42 Specification is recognized internationally as a benchmark for evaluating the chemical resistance and long-term stability of HDPE geomembranes used in extreme conditions.

Through accelerated exposure procedures, this method provides significant time savings by helping to:

  • Quantify oxidative degradation caused by exposure to chemicals, heat, and light;
  • Predict the long-term performance of geomembranes in demanding environments;
  • Reduce risks associated with premature containment system failures;
  • Support the selection and qualification of materials for critical applications.

This method is particularly relevant to the mining, industrial, and environmental sectors, as well as waste and tailings containment infrastructure.

A Laboratory Equipped to GRI Standards

To deliver this service in accordance with industry and laboratory best practices, SAGEOS has invested in specialized equipment and advanced training for its technical staff.

Our facilities enable:

  • Testing under controlled and accelerated exposure conditions;
  • The implementation of rigorous protocols that ensure compliance, accuracy, and repeatability of results;
  • Detailed analysis of oxidation mechanisms and polymer properties;
  • Comprehensive technical reporting supported by expert interpretation.

The addition of this method further establishes SAGEOS as a leading center of expertise in geosynthetics durability testing.

Comprehensive, Tailored Support

Beyond the testing itself, SAGEOS offers a full range of support services upon request, including:

  • Advanced interpretation of test results;
  • Recommendations regarding material performance and selection;
  • Integration of testing into quality assurance programs and qualification plans;
  • Collaboration with manufacturers, engineers, and asset owners.
