An efficient, cost-saving system and method of designing, installing, testing, and monitoring a secondary containment system for new and existing Above Ground Storage Tanks (ASTs) that is comprised of a protective steel membrane for the floor of the tank, including the floor-to-wall juncture, and the lower portion of the tank shell such that the steel membrane creates one or more interstitial zones between the steel membrane and the tank shell. The steel membrane may be installed zone by zone such that the secondary containment system can encapsulate existing tank features by molding itself around the existing contours, such as repair plates, corners, sumps, etc. Furthermore, a unique testing method using a simple electronic device is provided for on-site testing of the integrity of the weld seams that may be efficiently used after each zone is installed without requiring that the entire tank be evacuated during the construction of other zones.

We claim: 1. A secondary containment system for a fluid containment structure, comprising:a primary surface having a horizontal floor portion and a vertical wall portion;a secondary surface comprised of a plurality of plates that are sealingly attached directly to the horizontal floor portion of the primary surface such that there exists an interstitial space between the primary and secondary surfaces; anda plurality of vertical expansion members that sealingly attach the plurality of plates of the secondary surface to the vertical wall portion of the primary surface.
