Reinforced slurry walls are derivatives of the diaphragm wall technology and are also commonly used by Bachy Soletanche to construct retaining structures. They have multiple functions that are retaining structures and water cut-off respectively. The wall thickness ranges from 800mm to 1500mm.
Reinforced slurry walls use the same excavation methods as for diaphragm walls. The trench is excavated under bentonite slurry by grab, chisel and/or hydrofraise, then replaced by bentonite-cement slurry with reinforced steel H sections. Shear pins can also be installed within the walls if required. Reinforced slurry walls are constructed panel by panel with overlapping to ensure the water tightness.
