ABSTRACT
Slurry walls are barriers constructed below the ground surface to arrest the flow of groundwater, and/or to provide structural support for a soil mass or a foundation. The terms slurry wall and slurry trench are often used interchangeably, but the adjective “trench” generally implies an unreinforced soil barrier, while the term “wall” implies a soil, soil-cement or concrete barrier reinforced with steel mesh or bars. Both slurry walls and trenches are accepted construction techniques that have been used for over half a century.
