Repairs to the Gennevilliers Viaduct
Project
When a section of walling supporting the roadway of the Gennevilliers viaduct collapsed, NGE Fondations was awarded the contract to carry out the repairs on the basis of its innovative AD/OC® (Self-Draining/Carbon Optimised) soil nail walling technique. Using this technique saves a considerable amount of time, because the prefabricated concrete slabs rest on top of each other, eliminating the need for the preliminary formwork phase.
