Creating cutoff walls to contain groundwater contamination requires slurry trench excavation. We dig narrow trenches using hydromill units, maintaining trench stability with bentonite slurry. Once reaching design depth, we place cement–bentonite or soil–bentonite backfill to form an impermeable barrier. Slurry is recovered and recycled on-site, minimizing waste. Stockton Demolition And Excavation’s slurry-trench expertise supports remediation projects and ensures containment systems meet environmental-engineering specifications.
