ABSTRACT
A case study is presented which focuses on the development and implementation of a restoration strategy that attempted to stabilize and restore durability to a severely deteriorated and damaged church bell tower. Investigations had confirmed that extensive lateral movement of buttress stone masonry units had occurred and a restoration strategy was therefore required which could restore durability to the structure while permitting ongoing movement to be better accommodated. The various stages of the restoration strategy are presented, including stabilization, strengthening and repointing of the masonry. Details of some of the limited rebuilding work are also presented, together with waterproofing, flashing procedures and other ancillary work.
