The very first fiberglass underground petroleum storage tank was a single-wall design and for 45 years single-wall tanks were installed around the world. As petroleum regulations changed single-wall tanks were phased out and although CSI no longer produces single-wall tanks for fuel storage, the original design is still utilized in other applications like water storage and separators/interceptors. Single-wall tanks use the same manufacturing methods and laminate matrix as our double-wall designs.
Typical single-wall tank applications:
