What Environmental Protection does

Environmental Protection, Inc. (EPI), operating as "The Liner Company," is a Traverse City, Michigan-based manufacturer of factory-fabricated geomembrane and geotextile liners founded in 1980. The company produces single-ply PVC geomembranes (10–60 mil), UltraTech EIA membranes, LLDPE liners, polypropylene floating covers, scrim-reinforced polyethylene, and complementary geotextile products. EPI's core process is custom fabrication in a controlled factory environment, producing panels up to 40,000 square feet that are accordion-folded and shipped for on-site installation; this approach reportedly reduces field seams by up to 80% versus field fabrication. Quality control relies on the proprietary Wolschon Test (in-process sampling of factory seams), Statistical Process Control, and use of first-quality virgin resins meeting ASTM D7176 and ASTM D7408.

EPI serves a diverse vertical set across the continental U.S., with primary segments being water and water treatment (municipal reservoirs, potable water, brine containment), waste management and landfills (liners, caps, coal ash basins), and oil and gas (drilling pit liners, secondary containment), plus secondary segments in mining (heap leach), agriculture and aquaculture, power generation, environmental remediation, and residential/landscape applications. Named customers include Holcim Dundee, the Columbus Upground Reservoir No. 2, and the Coachella Canal. The firm maintains active membership in five industry/standards organizations (Geosynthetic Research Institute, Flexible Geomembrane Institute, ASTM International, International Association of Geosynthetic Installers, Michigan Oil and Gas Association) and has ongoing technical research collaborations with Syracuse University and TRI/Environmental.

The business model is sales-led and project-based. EPI sells directly via a quote-request workflow coordinated through sales and technical service representatives, with custom-fabricated panels priced per-project and a smaller standard-inventory channel serving smaller pond/landscape customers. Installation is coordinated through a network of independent contractors across the continental U.S. rather than via employed crews. Pricing is not publicly disclosed. The company is privately held with no disclosed funding rounds, no parent entity, no subsidiaries, and no M&A activity; it is also known to have recorded zero warranty claims across more than one billion square feet of cumulative shipments. EPI was founded in 1980 and remains operating, with US-based operations centered on a single Traverse City headquarters and manufacturing facility.
