SLURRY WALLS
The excavation method is similar to the one used for traditional reinforced concrete diaphragms walls. The main difference is in the materials used and in the purpose of the works.
The diaphragm walls are built without reinforcement cages and concrete: in fact, they are made up of the same bentonite slurry used for the excavation, which is then added to cement. The cement has the purpose to provide strength and an appropriate plasticity in order to ensure integrity over time.
Rather than structures, they can be considered ground lenses with improved geomechanical characteristics. They are perfect for waterproofing river dams, landfills sites, earth dam cores, and whenever it is preferred to eliminate water flows or fluids in general rather than the action of soil containment, typical of bulkheads. Worthy of note is the environmental value of this technique.
