Frequently Asked Questions about EIA Geomembrane

EIA stands for Ethylene Interpolymer Alloy. E Squared’s EIA geomembranes are based on DuPont Elvaloy resin technology — Elvaloy is DuPont’s trade name for the Ethylene Interpolymer Alloy compound, which provides the product’s hallmark combination of flexibility, UV resistance, and chemical durability.

EIA geomembrane excels in potable water containment, oil and gas secondary containment, hydrocarbon storage, exposed reservoir covers, and energy industry applications. Its UV resistance and chemical stability make it especially suited for above-grade and long-term exposed installations.

Yes. E Squared’s EIA geomembranes are available in NSF-certified configurations approved for potable water contact, making them a trusted choice for drinking water reservoirs, municipal storage tanks, and water treatment facilities.

E Squared’s EIA family is available in single ply, 2-ply, and 3-ply composite designs. Each configuration is engineered to meet specific load, chemical exposure, and installation requirements. Contact our team or download our data sheets to identify the right option for your project.

EIA offers superior flexibility compared to HDPE, making it easier to install on irregular terrain without the need for heat. Compared to PVC, EIA provides better long-term UV resistance and chemical stability, particularly in hydrocarbon-rich environments and exposed above-grade applications.

Elvaloy is DuPont’s proprietary Ethylene Interpolymer Alloy resin used as the base material in E Squared’s EIA geomembranes. It delivers an exceptional combination of flexibility, chemical resistance, and long-term durability — particularly in exposed installation and hydrocarbon containment environments where other materials fall short.
