How EFI USA Compares

MidAmerica Liner, founded in 2008, installs HDPE liners and anaerobic covers across the central United States. See how EFI's national coverage, 500+ covered lagoon digesters, gas treatment, and three fabrication hubs compare.

IEC is a cover and liner specialist incorporated in 1993, known for modular and insulated covers, including digester and gas storage covers. Compare that scope against EFI's 500+ covered lagoon digesters and the gas treatment, flaring, and monitoring behind them.

Chesapeake Containment Systems, founded in 2007, installs geosynthetics and HDPE piping along the Eastern seaboard. Compare that regional focus against EFI's national presence, integrated service lines, and decades of project data.

Western Environmental Liner, a division of Western Ag Enterprises, manufactures, fabricates, and installs geomembrane liners from plants in Arizona, Kansas, and New York. Compare that liner-first model against EFI's integrated biogas systems, covered lagoon digesters, and gas treatment.

GSE Environmental (now Solmax) is primarily a geomembrane manufacturer, not an installation contractor. Compare a material supplier against EFI's full-service model: design, fabrication, installation, QA, and post-install support under one contract.
