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. Beyond our western installation crews, EFI USA brings national capabilities that go beyond installation: engineered biogas and anaerobic digester systems, covered and floating lagoon systems, and cap-and-flare and gas-handling design and construction. Same people, same standards, a full-scope containment and biogas team within reach of nearly any site in the country.

EC Applications installed both the base liner and the floating cover on a potable water reservoir just under two acres in size, a total area of geosynthetics of just less than four acres. The reservoir's previous cover was some 30 years old, had exceeded its useful design life, and was in urgent need of repair to prevent the stored drinking water from being contaminated. Carollo Engineers was the design engineer and carried out the detailed design, working with Seaman Corporation on material selection and with EC Applications on construction. Seaman's XR-PW was chosen for the primary liner system, the floating cover, and all of the appurtenances. It is one of only a few products carrying NSF approval for potable water use, and it can be seamed efficiently at the time of original installation and re-welded throughout the life of the reservoir with the same heat welds used for routine repairs.
