Cut-off Walls (Slurry Wall)

Cut-off Walls (Slurry Wall) involves the excavation of a narrow trench under an engineered fluid (slurry of grout) to create a non-structural barrier to impede water intrusion and prevent sloughing and soil caving. Slurry walls are commonly used to contain contaminated soils, strengthening soil prior to excavations and to prevent water intrusion.
