60 mil (1.5 mm) HDPE geomembranes continue to be one of the most trusted and frequently specified thicknesses for primary containment systems in 2026. This robust gauge delivers the ideal balance between mechanical strength, chemical resistance, long-term durability, and reasonable installation economics — making it the industry standard for many high-risk and critical applications.
According to the Geosynthetic Institute (GSI) 2024–2026 global installation statistics and International Geosynthetics Society (IGS) market reports, 1.5 mm HDPE geomembranes represent ~24–32% of total HDPE volume installed worldwide in 2024 — second only to 1.0 mm (40 mil) but ahead of 2.0 mm (80 mil) and thicker gauges.
This thickness is explicitly approved by:
- EPA Subtitle D for landfill base liners
- Most state solid waste regulations
- MSHA and international mining authorities for heap leach pads & tailings dams
- Numerous engineering specifications (GRI-GM13 compliant)
