1. THE MINUS 200 SIEVE CONTENT OF THE SOIL- BENTONITE BACKFILL
SHOULD BE IN THE RANGE OF 30 TO 40%. THE SPECIFIED
MINIMUM IS 30X. BACKFILL SHALL BE CAREFULLY MONITORED
DURING CONSTRUCTION. BECAUSE OF VARIABLE SOIL CONDITIONS.
1.OX ADDED DRY BENTONITE BY WEIGHT HAS BEEN SPECIFIED FOR
THE ENTIRE SLURRY WALL ALIGNMENT.
