Hoover Building Structural Renovations

Hoover Building

Structural Renovations Limited has recently completed a 12 month concrete repair and specialist coating project at the iconic Hoover Building in Perivale, West London.

The building was constructed as a factory for the Hoover Company in 1933 to the design of Wallis, Gilbert & Partners, who were inspired by the Mayan and Aztec fashion displayed at the 1925 Paris Exhibition and remained operational until its closure in the 1982.

During the Second World War the factory was used to manufacture parts for various aircraft and the building was camouflaged with netting to help avoid being attacked.

Being of significant architectural importance the building was Grade II* listed in October 1980 and in 1989 Tesco purchased the site and set about converting the rear into a large supermarket, including sympathetic recreations of various original building motifs around its entrance and car park.

In 2016 Structural Renovations were employed to carry out a condition survey of the concrete to the original structure and from the results of the survey we developed a specification for its repair and protection, based on the use Sika products.

We were duly instructed in March 2017 to commence the repair and restoration works and following an initial clean we were able to identify all spalling/defective concrete. Where required the concrete was repaired using a polymer modified repair system, combined with the installation of a vapour phase inhibitor, to control any ongoing corrosion in the embedded reinforcement.

Previously painted areas received a multi-coat elastomeric system and unpainted elements of the building had a clear anti-carbonation coating applied.

Finally, all existing sealants at the junction between window frames and painted concrete were raked out, prepared by priming and reinstated with a one part low modulus sealant.

During our external works the internal areas of the original building were converted into 66 luxury apartments by IDM Properties.

We are proud to have been involved in prolonging the life of this prestigious example of Art Deco architecture and it demonstrates the capabilities of our Company.
