Depending on location and material availability, these materials can be more costly, but permeability values in the range of 108 cm/sec and strengths in excess of 80 psi (05 MPa) are possible after 90 days of Nontraditional methods of slurry cutoff wall construction include the vibrating beam method A vibratory hammer is used to drive special steel beams to design depth along the wall Slurry cutoff walls Keller North America

Soil Bentonite Slurry Trench Cutoff Walls: History, Design, and

Slurry trench cutoff walls have been widely used for over 70 years to control groundwater flow, seepage through dams and levees, and contaminant transport Slurry cutoff walls are nonstructural underground walls that serve as a barrier to the horizontal flow of water and other fluids This technique is typically used to build walls Slurry Walls Cement
