Geosynthetic Installation, Environmental Containment
Top-level geosynthetic containment, installed right.
Our people and experience make the difference. Liners, covers, and containment systems engineered, fabricated, and installed by the most experienced crews in the industry.
Full-scope geosynthetic containment
One contractor for engineering, fabrication, and field installation across every containment application, simple or complex, big or small.
Our people and experience make the difference
The reasons owners and engineers trust our crews with critical containment, from the weld to the final test.
Full scope, one contractor
Engineering, fabrication, field installation, and maintenance under one roof, with one team accountable for the whole system.
Custom panels up to 25,000 SF
We fabricate custom geomembrane panels up to 25,000 SF and stock off-the-shelf options for rapid deployment.
Vacuum and smoke tested barriers
Methane barrier seams are vacuum and smoke tested for a leak-proof system before handoff.
60+ years combined, hundreds in the field
Our management team carries 60-plus years of combined geosynthetic lining experience and our crews represent hundreds of years collectively.
Two California CSLB licenses
Licenses #894068 and #1003207, verifiable through the state board.
Nationwide, coast to coast
Crews mobilize from our California, Texas, and Nevada offices to projects across the country.
One team, the full lifecycle
From the first drawing to long-term maintenance, the same crews stay with your containment system.
Design and Engineering
We engineer the containment system and detail materials and seam layout for your site and spec.
Fabrication
Panels are custom-fabricated in-house up to 25,000 SF, with stocked off-the-shelf options when speed matters.
Field Installation
Our crews are the most experienced in the industry. They consistently deliver high quality installations with unparalleled customer service.
Maintenance
We maintain and repair systems over their service life so containment keeps performing.
West Coast strength, now part of a national team
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.
- Regional offices in Anaheim CA, Midland TX, and Sparks NV
- Shared engineering, fabrication, and field expertise
- One call for projects from coast to coast
Project video · 2:17Potable Water Reservoir Liner and Floating Cover, El Dorado Irrigation District
El Dorado Irrigation District, California
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.
