Soil-Bentonite Slurry Cut-Off Wall Sample Spec
Slurry Wall Construction in Brisbane, Australia. The project is designed to isolate an area where vacuum consolidation is planned. The wall has plastic liner placed in the zone above the local water table to prevent air from entering the site as the vacuum is applied.

The soil-bentonite slurry wall (SB slurry wall) is by far the most popular type of slurry wall constructed in the United States. Approximately 90% of all slurry walls are either SB or Soil-cement-bentonite (SCB), a closely related technology.
The Benefits of Soil-Bentonite Slurry Wall Barriers
The soil-bentonite slurry wall represents numerous technical advantages over competing barrier technologies. These include:
Rapid construction time, usually using extended reach excavators.
Re-use of most of the excavated spoils, including in situations where the spoils are contaminated
Low permeability that can be controlled by adding any necessary additives as the backfill is mixed on the surface
Excellent resistance to contaminated groundwater for a wide variety of contaminants.
Lowest cost of any groundwater barrier technology
Soil-Bentonite Slurry Wall Projects
For all of these reasons, the soil-bentonite slurry wall has been the technique of choice on thousands of slurry wall projects throughout the US over the past 30 years with a few applications even earlier than that. A soil-bentonite slurry wall may be used for numerous applications, including:
Containment of contaminated groundwater
Correction of under seepage under levees and dams
Dewatering of large excavations
And many others
