which one is preferable and mostly recommendable among the following? Soil-bentonite slurry trench or cement-bentonite slurry or Bitumine-bentonite slurry trench for backfill?
because they're creating an impermeable barrier around the site that contaminated groundwater cannot pass through... so they're replacing the permeable soil with an impermeable bentonite wall.

so the bentonite is poured in after ground water is hit to support the trench will digging ?
good job
Why are you digging a trench then backfilling it right away with native material? Doesn’t backfilling defeat the purpose of the trench?

what type of chemicals used to increase the permeability in PBR
