At IEC, we’re proud to be an innovator and industry leader of geomembrane covers and liners. Geomembrane liners and covers are generally defined as very low permeability synthetic membrane barriers that are used for the purpose of controlling the migration of fluids, vapors, and gases. Geomembrane liner and cover systems are widely used as impermeable barriers for liquids, vapors, and gases, and feature a wide variety of environmental and civil applications for municipalities, industry, oil and gas, mining, and agriculture.   IEC utilizes geomembranes of the highest quality available in the industry. We offer a wide variety of geomembrane liner and cover materials, including high-density polyethylene (HDPE) and linear-low density polyethylene (LLDPE), which are the two most common materials used for containment. Both materials offer high strength and durability, and are resistant to most chemicals and useful over a wide range of temperatures.

Here are some of our latest solutions:


We’re proud to offer the new, patented Quick-Stairs safety stairway system. This adaptable and adjustable, nonslip stairway system makes traversing lined slopes both safe and simple. Quick-Stairs can be provided in any length and can be used on geomembrane liners without puncturing them. LEARN MORE HERE
