Are you trying to determine the most effective and cost efficient method to configure a new or used above ground liquid storage tank? This article explains why in most situations the answer is using a PVC tank liner. Using a tank liner is an effective method for secondary containment and less expensive than standard containment options.

Tank liner systems use an internal flexible membrane made from radio frequency sealed virgin polyvinyl chloride (PVC) material. This membrane creates a barrier between the liquid being stored and the tank floor and wall.

A potential drawback of using a PVC liner is the need for caution when walking on or cleaning the liner. Clearly PVC is a penetrable material, so care is required to not accidentally introduce sharp objects to the liner via filling from a barge or on an employee’s shoe. However, if a puncture is made in the liner, it is easier to fix than a hole in a steel tank.

The PVC liner is compatible in storing a variety of liquids, including most fertilizers, water, molasses, catsup, various oils (cotton seed, linseed, mineral, olive, palm, peanut, etc.), ethyl and propyl alcohol, beer, wine, rum, and many more. The main limitations in being able to use a tank liner are the compatibility of the liquid product being stored, storage of liquids at high temperature (sustained temperature of 120 degrees and higher), and whether the state permits PVC liners as secondary containment.
