GRI GM42: The Next Step in Geomembrane Design — But Only If We Use It Right
For nearly three decades, GRI GM13 has been the benchmark specification for HDPE geomembranes. It was a strong foundation for its time, focusing on UV resistance and general durability in waste containment. But the world has changed. Containment facilities are no longer just landfills; they’re complex, chemically aggressive, and high-risk environments, from tailings to PFAS ponds and salt harvesting pads. That’s why GRI GM42 was developed. Why GM42 Was Developed GRI GM42 was
