bentonite water absorption

How much does bentonite waterproofing cost? - Waterproof ...

Bentonite is an absorbent clay of volcanic origin. It is used for waterproofing purposes due to its ability to expand in contact with water. When bentonite and water touch, the clay expands its volume and turns into a gelatinous mass. As a matter of fact, bentonite can absorb 7 to 10 times its own weight in water.

Bentonite - Wikipedia

Bentonite (/ ˈ b ɛ n. t ə ˌ n aɪ t /) is an absorbent swelling clay consisting mostly of montmorillonite.It usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to clay minerals. Bentonite beds are white or pale blue or green in fresh exposures, turning to a cream color and then yellow, red, or brown as the exposure is weathered ...
