Gloucester Road Underground Station

The works involved:

The highly glazed red faience finishes were extensively fractured due to structural steel corroding and expanding.
Faience is a brittle material and generally cannot accommodate such forces therefore careful recording of the effected areas was required, details and sections were taken to enable the production of some 400 individual replacement units.
A large element of the project concerned the unique cathodic protection technique applied from within the building.
Small holes were drilled through the internal brickwork, anodes attached to the steel and a charge applied.
The object was to restrict future rusting causing similar damage.
Finally the decorative facades were cleaned, pointed and new signage incorporated.
