ABSTRACT:
A membrane provides a secondary containment system for a fuel storage system. The membrane is stressed by the heaving and sinking of the earth supporting the membrane. A pipe passes through and is bonded to the membrane. A bushing absorbs and distributes the stresses within the membrane to protect the bond between the pipe and the membrane.
