The ratcheting reaction assembly remains engaged with the proximal end of the outer clad as the housing is repositioned uphole to permit staged expansion of the outer clad using the first expander. The expansion tool improves sealing and structure integrity of the expanded outer clad within the casing by maintaining the outer 25 clad in a position throughout the staged expansion process. 261 260 \ la i ii 140 144 11 .4 269 t:t kr) 64 299 - © 11 IN 1-1 .
