Key Case Study

Parliament Buildings, Stormont

Location: Belfast, Northern Ireland
Client: Northern Island Assembly
Problem: Corrosion in concrete roof slab
Solution: DUOGUARD™

The Parliament building at Stormont, Belfast was built between 1927 and 1932. It is a B+ Listed Neo Classical building, and was built from Portland Limestone and Mourne Granite. The ground floor has square rusticated columns supporting six giant iconic columns and a pediment which covers office accommodation below.

Problem

The steel reinforced concrete roof of the pediment had been allowing water ingress for some time and as a result the steel had been corroding, causing cracking and spalling in the concrete. However, since the building was in constant use consideration had to be given to the disruption potential of carrying out major repairs.

Solution

Following a condition survey an effective repair and long-term protection strategy was implemented including the installation of DuoGuard™ Hybrid Anodes™ to control corrosion and prevent further deterioration of the reinforced concrete.

To minimise disturbance, including noise generation, CPT designed a solution requiring minimal concrete removal. The work was carried out quickly and efficiently and the area handed back to the main contractor on schedule ready for an internal fit out.
