Innovation

The Freyssinet group has been linked from the start to the idea and values of innovation, and devotes more than 1.5% of its turnover to research and development.
This year, its technical achievements have included the Cohestrand cable system applied to suspended bridges, which constituted a major innovation for Freyssinet with its first application on an industrial scale on the Kanne bridge (Belgium). The system guarantees a maintenance-free cable lifetime of over 100 years, and won the Grand Prize at the 2005 VINCI Innovation Awards.
In the field of MSE, Reinforced Earth developed and implemented the Omega connection on a first site near Morzine (France). The connection is a synthetic high tenacity polyester-based reinforcement strip made up of a continuous loop, the shape of which resembles the Greek letter that gives it its name. Partly cast into the panel during the prefabrication stage, this new corrosion-resistant fastener has other advantages, including simplifying the process of erecting walls, as it reduces the number of components delivered to site, an anchor that guarantees optimum pull-out strength, and compatibility with any type of concrete panel. Finally, Menard developed a new stone column machine equipped with rear legs that enable it to achieve record production rates of 500m per day (compared with 250m with a conventional machine) and establish the columns at depths of up to 16m due to increased thrust, thus improving the quality of the columns.
