The Diaphragm Wall are walls built in the underground starting from the surface. The excavating system consists of a Grab bucket with the same thickness of the wall to be built. The excavation is carried out with primary and secondary panels, with bentonite or polymeric slurry. The wall can be used as excavation support, foundation element or as containment structure for the flow of underground water.
