What Are Water Tank Liners?

Water tank liners are fabricated inhouse at our controlled and clean shop in Avondale, AZ. Utilizing our specialty welding machinery and experience of decades of water tank liner fabrication and installation, FLSI is able to make virtually any size and/or shape water tank liner. Panels of the flexible plastic of choice for your application are cut, then welded using one of our various welding methods, and finished with any needed accessories prior to shipment. This enables minimal limitations for FLSI based on your projects complexity. When fabrication is done, your liner can either be installed by your crews or ours.

From concrete to steel tank reservoirs both above ground, semi-in-ground and in-ground reservoirs, FLSI has the knowledge and experience to successfully complete almost any water tank lining project. FLSI is one of the only fabrication and installation companies in the US that has the ability to pre-fabricate panels in our state-of-the-art facility and proceed to install. This allows FLSI to complete our installation faster, safer and greatly reduces the amount of field seams.
