Long-Term Performance of Geomembranes in Mining Environments
Why chemistry (not just pH) should drive liner selection Disclosure. The findings cited below are from Silva, Rowe & Abdelaal (2025). The three 1.5 …
Raising the Bar: Why Atarfil “HD” Redefines the GM13 Standard for HDPE Liners
Introduction Atarfil’s base-level HDPE geomembrane (often marketed as Atarfil HD, “GRI GM13”-compliant) is engineered to deliver performance characteristics far exceeding the GM13 minimum requirements. …
HDPE Geomembrane Density and Polymer Structure
High-density polyethylene (HDPE) is a semi-crystalline polymer composed of tightly folded chain segments (crystallites) interspersed with disordered, amorphous regions. Crystalline regions pack chains closely, …
Achieving Environmental Safety and Longevity: A Deep Dive into Geomembrane Leak Rates and the Imperative for High-Quality Liners
In today’s environmental landscape, ensuring the integrity of geomembrane liners is non-negotiable. These barriers, commonly made of High-Density Polyethylene (HDPE), are the frontline defence …
Carbon Black in HDPE Geomembranes: Getting the Balance Right
Carbon black plays a vital role in HDPE geomembranes, providing UV protection and preventing polymer degradation. But when it comes to performance, more isn’t …
The Reflective Advantage: Comparing White and Black HDPE Geomembranes
High-density polyethylene (HDPE) geomembranes are widely used for applications such as containment, lining, and environmental protection. A critical consideration in choosing the right HDPE …
Evolving Beyond GRI GM13: Atarfil’s AC and AR Geomembranes for Advanced Containment
In the world of geomembranes, GRI GM13 has been a cornerstone specification for decades, providing a minimum standard for HDPE geomembranes to ensure baseline …
Are Your HDPE Geomembranes Really Designed for the Long Term?
In demanding environments, from MSW landfills to industrial waste containment, durability is a must. However, many industry norms and standards leave critical gaps in …
Why not all HDPE geomembranes are the same
Geomembranes, especially high-density polyethylene (HDPE) geomembranes, play a crucial role in high-risk containment applications such as mining, landfills and tailings dams. They are often …
Geomembrane Degradation Processes
High-density polyethylene (HDPE) geomembranes are widely used in containment applications, such as landfills and water ponds, due to their durability and chemical resistance. However, …
