Carillion Construction were commissioned to undertake an extensive modernisation of a selection of campus buildings within University of Wales, Swansea.

Beton Bauen Limited were brought on board to inspect the structural concrete at Faraday Tower, University of Wales, Swansea. The Faraday Tower (built c. 1965) is a seven- story tower block constructed using a combination of concrete and steel frame.

On inspection of the roof area and the supporting columns on the ground floor we concluded along with Carillion Construction that repairs were required to roof lintels above doorways and extensive repairs to all ground floor columns that were showing signs of deterioration.

As clearly illustrated in the photographs, we needed to diamond saw cut and breakout delaminated concrete to expose the 40mm re-enforcement steel bars that showed signs of fatigue.

Work Procedure
All delaminated concrete required removing and protective coatings applied to the exposed steel reinforcement before structural concrete repair mortars were applied.  Finally decorative ant-carbonation coatings were applied to blend in and meet with the Architects requirements.

Not only the columns were refurbished but also the undercroft  required cleaning by high pressure water jetting, followed by localized concrete repairs and the application of the same anti carbonation coating.

Work was complete within 5 days. An agreed colour was applied to compliment the new exterior cladding to the building that was carried out by Carillion Construction. White bands where masked and painted at an agreed height to warn motorists of the columns location as the area is used as a car park for staff.
