The age of the buildings combined with environmental factors has resulted in spalling of concrete at various areas across the hospital. Defective concrete has been removed and concrete repairs undertaken using cementitious repair materials.
To prolong future use of the building, a cementitious coating has been used to protect steel rebar from further corrosion. The highly alkaline coating passivates the steel surface chemically to prevent further rust formation. It protects the steel from moisture, gasses and chlorides.
With patient and public safety core drivers of the project repair materials were hand applied. On sensitive sites such as hospitals, CSC Services can use a range of concrete protection products and application methods to minimise disruption.
All work undertaken was in accordance with the BSEN1504 standard, in which all operatives are fully trained. CSC Services are members of the Concrete Repair Association. Membership is a way to further demonstrate competence in concrete protection to clients.
