Sodium Bentonite is utilized as a pond sealant due to its high swelling capacity
Natural sodium bentonite is a hydrous silicate of alumina made up mostly of montmorillonite. This clay swells several times its own volume when water is added.Sodium bentonite is in either granular or powdered form. It is often used in sealing and lining applications that involve wet soils.Bentonite is made up of volcanic ash deposited in an evaporite and then changed by geological processes to become sodium bentonite. It is estimated that bentonites formed approximately 70 million years ago. Southern Saskatchewan was at the heart of a massive deep inland sea that spanned from the North Sea to present day Mexico. At the time it was at least 1600 kilometers wide.
Bentonite has been deemed the “clay of 1000 uses.” Sodium bentonite is known for its affinity with water. The sodium bentonite disperses water into microscopic tray particles that are acidified on the surface and positively charged at the margins. The binding activity due to this one of a kind ion exchange. The bentonite tiny tray particles have a massive and considerable surface area potential. Even though the amount of bentonite in such gels is relatively small, it produces thixotropic gels with water. Bentonite is equipped with a wide range of potential applications as a result of these qualities. As an example this unique clay can be utilized as an organic soil sealant or a livestock feed binder.
Worldwide bentonite resources are abundant , but their distribution is unbalanced.

The #40 is granular and often used in sealing and lining applications that involve wet soils. It is also used in conditions that need to minimize dust particles.
