    Water. Bentonite independent of type should be rehydrated with clean chlorine-free hot (60 °C 140 °F) water by adding it under vigorous mixing to the water (not the other way around) and allowing it to swell for at least four hours. The lump-free slurry shouldn t sit longer than overnight either as this may encourage microbial growth.

    (b) This phenomena seems to indicate that the stronger the water absorption property of the bentonite particles the greater the amount of OH-ions and H 2 O are taken from the sodium silicate. This can be illustrated because when the water absorption is maximum the viscosity reaches maximum and the pH value is lowest and stops falling.

    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.
