In the autumn of 2020, Villiger AG in the city of Cologne converted around 60 underfloor systems from competitors to the Villiger system. Thanks to its in-house design, Villiger has the necessary resources to develop customer-specific systems. For example, existing concrete containers in Cologne were reused by competitors and the Villiger system adapted to this were installed. The result can be seen in Cologne.
