Geosynthetic Installation, Environmental Containment
Our people and experience make the difference. Liners, covers, and containment systems engineered, fabricated, and installed by the most experienced crews in the industry.
One contractor for engineering, fabrication, and field installation across every containment application, simple or complex, big or small.
The reasons owners and engineers trust our crews with critical containment, from the weld to the final test.
Engineering, fabrication, field installation, and maintenance under one roof, with one team accountable for the whole system.
We fabricate custom geomembrane panels up to 25,000 SF and stock off-the-shelf options for rapid deployment.
Methane barrier seams are vacuum and smoke tested for a leak-proof system before handoff.
Our management team carries 60-plus years of combined geosynthetic lining experience and our crews represent hundreds of years collectively.
Licenses #894068 and #1003207, verifiable through the state board.
Crews mobilize from our California, Texas, and Nevada offices to projects across the country.
From the first drawing to long-term maintenance, the same crews stay with your containment system.
We engineer the containment system and detail materials and seam layout for your site and spec.
Panels are custom-fabricated in-house up to 25,000 SF, with stocked off-the-shelf options when speed matters.
Our crews are the most experienced in the industry. They consistently deliver high quality installations with unparalleled customer service.
We maintain and repair systems over their service life so containment keeps performing.
EC Applications (ECA) has joined EFI USA. We pair our western installation crews with EFI's East Coast operations, putting a full-scope containment team within reach of nearly any site in the country. Same people, same standards, more capability.

Hawaii · 2009
A 600,000 SF biogas cover and passive methane barrier installed over an existing lagoon in multiple phases, coordinated across simultaneous contractor crews. The installation included over 150 penetrations through the liner. All seams were vacuum tested and the installation was smoke tested for a leak-proof system.
