Key Facts

  • KM Bentonite Pellets
  • Supplied in 25 kg plastic sacks.
  • For large jobs supplied in 1-tonne big bags or loose in 20 or 30 tonne tipper trucks.
  • After wetting ("hydration") with fresh water swells to > 150% of original volume.
  • Delayed Hydration.  Will drop to bottom of most wells before swelling.
