The Seine-Nord Europe Canal project represents a new approach to the management of major projects, which is innovative, efficient and sustainable. It seeks in particular to facilitate the crossing of the Canal during and after the work or to reuse the excavated earth and limit its transport.
The Société du Canal Seine-Nord-Europe (SCSNE) has the ambition to make a project emblematic of the ecological and energy transition and attentive to territorial issues. The management of cuttings and material flows is a major environmental and societal challenge, and the construction of the Seine-Nord Europe Canal will generate very large volumes of earthworks, of the order of several tens of millions of cubic meters, and will require supplies of external materials (lime, binders, aggregates, steel) and several million tons.
On October 1, 2020, the SCSNE Supervisory Board approved a plan for the supply of materials and the management of cuttings which defines the strategy for controlling the economic, societal and environmental impacts from the design study phase to the execution of works.
Its main objectives revolve around the principles ofeco-performance, Partnerships andinnovation who lead the project:
The reuse of natural earth extracted on the Seine-Nord Europe Canal site reduces landfilling, extraction of raw materials and transport. The SCSNE has launched a study to replace the quarry or manufactured products used to make the waterproofing layer and protect the bottom of the canal with silt and chalk treated with certain additives (bentonite, kaolinite, hydraulic binders, etc.).

In Cizancourt in the Somme, an experiment made it possible to test this full-scale process in a 400 m2 test basin. For 12 months, optical fibres, probes and electrical wires measured the resistance, permeability and behavior of peripheral dikes. Mechanical tests (erosion resistance) were also carried out. The first results are very positive:
The waterproofing layer composed of silts extracted on site meets the expected permeability objectives
The binder-added silts or chalks provide sufficient mechanical strength for use as a protective layer.
The Société du Canal Seine-Nord Europe and the Entente Oise-Aisne have signed an agreement for the provision of 400 m000 of excavated material on Sector 3 of the Canal (1 km from Compiègne to Passel in the Oise) for the needs of the Entente Oise-Aisne, for its project to increase flood storage capacity near Longueil-Sainte-Marie. The materials will preferably be transported by waterway.
Each of the locks of the Seine-Nord Europe Canal has been designed by the teams of the Société du Canal Seine-Nord Europe to respect ambitious environmental criteria: to limit the use of new materials, the walls of the locks, called bajoyers, will be composed concrete and local materials such as treated silt. This innovative solution is the subject of a full-scale test program near Marquion: a lock wall has been built there!
The SCSNE and VNF have joined forces to enable all future players to better understand the waterway professions and their mode of use. They thus provide a synopsis which aims to provide everyone with a better knowledge of transport by waterway. You will find some feedback, transport hypotheses, carrying capacities and organization of the river sector, and the construction of construction chains.
