Sodium Bentonite Powder is an absorbent natural clay made from weathered volcanic ash that swells significantly when it absorbs water. It is widely used in construction, drilling, foundry, cosmetics, agriculture, and water treatment industries due to its excellent binding, swelling, and sealing properties.

Bentonite used as liquid slurry during bored pilling to stabilize drilling holes and prevent soil collapse before pouring concrete. The mixture act as a liquid when stirred or pumped, but thickens into a gel like state when it sits still to support the soil walls.
