Concrete repairs scheduled over several years
Hangar C at the Condat Group’s lubricants plant was built entirely from reinforced concrete during the interwar years. The structure was suffering from the typical tell-tale signs of ageing concrete, with spalling and cracks appearing in the thin arches (12 cm thick) forming the roof, and the roof structure components (tie beams and hangers). As part of our client’s asset development strategy, repairs were scheduled in phases spread over several years. Early 2020, the teams at Freyssinet Rhône-Alpes Auvergne were contracted to carry out annual concrete repairs on the structures for the fifth time in 10 years.
