Properties | Bentonite

Sodium bentonite, with sodium cation prevalence (Na+) allows water to penetrate through the platelets, forcing them apart, thus leading to swelling. Conversely, calcium bentonite, with calcium cation prevalence (Ca2+), while getting hydrated in much the same way, due to its strong positive charge, has lower absorption properties, not permitting water to penetrate through the platelets.

ISO - ISO 10769:2011 - Clay geosynthetic barriers

ISO 10769:2011 specifies a method for determining the water absorption of bentonite. The bentonite component is a part of clay geosynthetic barriers (GBR-C). Water absorption depends on the specific surface of the fine particles and the surface activity of the bentonite. The test provides an index value for production control testing of GBR-C.

Bentonite Waterproofing | What are the

Bentonite waterproofing is an exterior waterproofing treatment that is supposed to work by forming a barrier between wet soil and the building foundation. Like any type of clay, bentonite absorbs moisture. As water molecules bond to clay particles, the clay expands, filling cracks and gaps in the foundation so that water can't get in.
