- wrapping, at tension, a self-amalgamating tape (24) around said layer of non-curing putty (22) to cover said layer of non-curing putty and form a tension wrapped region at said location of said leak;
- contacting a flexible sheet or tape (30) with either:
- a resin, or
- water to activate a water-activated matrix component;
- and
- encompassing the self-amalgamating tape (24) with the flexible sheet or tape (30) such that the resin or water-activated matrix component binds with the flexible sheet or tape (30) to form an outer shell with the flexible sheet or tape (30) to substantially surround said tension wrapped region.
