Abstract

A trench or slot is excavated along the desired line of the impervious barrier in the presence of a bentonite slurry. A double layered plastic film or sheet joined or folded at the bottom of the trench (T) to form a sheath or envelope (F) and open at the top and of sufficient vertical extent to extend above the ground and drape on both sides of the trench (T) is installed in the trench and as the plastic sheath or envelope (F) is installed in the trench (T) it is hydraulically backfilled between the two facing surfaces thereof with a backfilling material (30) having a greater density than the density of the bentonite slurry (B) to sink the double layer plastic film or sheet (F) to the bottom of the trench (T) and displace the bentonite slurry (B) forward in the trench (T) toward the end being excavated.
