Cathodic protection and condition monitoring: residential tower block, N. Lanarkshire

摘要

This paper discusses the design and installation of a cathodic protection system and a condition-monitoring system to an 18-storey tower block in North Lanarkshire. The tower block is to have a rainscreen overcladding system erected as part of a programme of refurbishment works being carried out by North Lanarkshire Council during 2000. An investigation by the Building Research Establishment revealed the presence of cast-in chlorides in the structural frame and questioned the longer-term integrity of some elements of the building. This paper discusses the appraisal of the tower block's condition, the remedial options considered, and the theory, design and installation of the treatment selected to ensure the integrity of both external and internal elements of the structure.
