A Foundation Built on Experience. A Future Driven by Purpose.

 

Evergreen Environmental Lining Company (EELCO) was founded with a clear purpose: to bring consistency, accountability, and long-term thinking to an industry that often struggles with short-term fixes.

​

Our story begins in the field—on job sites where details matter, safety is non-negotiable, and reputation is earned one project at a time. For decades, our team worked across every facet of the geosynthetics industry: installation, estimating, project management, business development, and management. We've been in the trenches, solved problems under pressure, and learned firsthand what it takes to deliver on a promise.

​

But we saw something missing. A better way to approach environmental lining—one that balances precision with practicality, and puts integrity at the center of every decision.

​

That’s what led us to create Evergreen Environmental Lining Company.

​

We didn't set out to be the biggest. We set out to be the most dependable. The most trusted. The most thoughtful about how we do the work, how we treat people, and how we leave things better than we found them.

​

We’re proud to be rooted in the Pacific Northwest—where environmental stewardship isn’t just a line in a mission statement, it’s a way of life. But our reach goes far beyond. Across industries and across the country, we partner with those who care about doing things right.

​

Today, Evergreen is more than a lining company. We’re a team of builders, thinkers, and problem-solvers who believe that doing excellent work—with clarity, honesty, and care—still matters. We bring that mindset to every project, and we’re building something we believe in: a stronger, cleaner, more sustainable future.
