Devon House - Structural Renovations - Concrete Repairs

Devon House

The 4th and 5th floors are currently being refurbished at Devon House and Structural Renovations have been employed to carry out the concrete repairs.

Devon House is situated on Great Portland Street and is part of the Langham Estate portfolio.

The floor slabs have been constructed from clinker concrete and steel filler joists. The filler joists have corroded and caused the concrete and plaster to crack and spall.

The defective concrete was removed from around the filler joists, the corrosion was removed by mechanical wire brushing and then the cleaned steel was primed with two coats of Fosroc Nitoprime Zincrich Plus. A galvanised mesh was fixed over the exposed steel and the concrete was reinstated with Fosroc Renderoc HB.
