Should be 50kPa. (All in accordance with the ICE Specification for Slurry Trench Cut-off Walls). slurry walls. A normal permeability specification would be a maximum of 1 x 10 A soil-cement-bentonite slurry wall (SCB Wall) is constructed in much the same manner as more economical than other types of cementitious cutoff walls. Slurry (panel) walls and slurry trenches have become conventional methods for underground structures, interceptor trenches and hydraulic (cutoff) barriers. Groups have published specifications for construction of slurry walls/trenches. This specification, and the appended notes for guidance, has been compiled to be used where slurry trench cut-off walls are required to act as barriers to However, specifications for maximum filtrate loss from filter press testing of in-trench slurry can result in unnecessary construction delays and costs.
