Slurry wall construction is a ground support and groundwater control method that involves excavating a trench and filling it with a bentonite or cement-bentonite slurry to form an impermeable barrier. Unlike diaphragm walls, which are reinforced structural elements, slurry walls are primarily constructed as cut-off walls to reduce groundwater inflow and prevent soil erosion during deep excavations or tunnelling works. The slurry in the trench stabilizes the excavation until the trench is backfil

We could go to great lengths explaining the modular design of our HSG 5-18 hydraulic slurry wall grab. OR we could just simply show you an animation that leaves no questions unanswered. http://www.liebherr.com/HS-series | Liebherr Construction
