Vérinage operations in Belfort

On June 20, Premys, a Colas company specializing in demolition, carried out vérinage operations, a technique that does not use explosives, on three 15-storey appartment building that had become unfit for habitation, in the Résidences district of Belfort in eastern France.

The patented vérinage technique consists in toppling the upper floors using hydraulic jacks, thereby crushing the lower floors, which minimizes the disruption associated with mechanical demolition as well as the time required to complete the operation. Protected by a safety perimeter, hundreds of local residents were able to watch the final phase of the demolition. The operation, initiated by real-estate management company Territoire Habitat, is part of an urban redevelopment project funded by the French National Urban Renovation Agency (ANRU).
