Drilling Grade Bentonite

Drilling Grade Bentonite

200 bbl Yield Bentonite is a superior quality Bentonite. It is 200 mesh powders. It is specially processed with chemicals to achieve require properties.

  • 200 bbl/ton yield.
  • Swells up to 16- 20 times to its size when it becomes wet.
  • Expands greatly and expanded Bentonite forms an impermeable gel seal which makes an excellent pond sealing.
  • Environmentally safe and does not affect the water and live stock or wild life when it use properly.
  • It does not harm fish.
  • Supporting suspension for cut of diaphragm wall construction and shield tunneling. 
  • Fast and easy mixing.
  • Control loss of drilling fluid.
  • Reduces solids and increase lifting power.
  • Cools drill bit and reduce filtration by forming a thin filter cake with low permeability.


Application :

  • Mixing ratio is based on the fresh water purity. Water quality will affect Bentonite performance.
  • Mixing ratio lbs/ 100 gallon of water 


Packing :

25 Kg HDPE/ Paper Bag, 50 Kg HDPE and 1000- 1250 Kg with liner.
