Slurry Trenches

By July 9, 2015 No Comments

Soil-bentonite slurry trenches are constructed by excavating and keying into a suitable cut-off stratum under a viscous slurry to maintain sidewall stability. The excavated material is mixed with bentonite and returned to the trench, displacing the slurry and completing the cut-off. When additional strength is required, cement grout may be added to the backfill.
