Abstract:
The present invention relates to improved bentonite barrier compositions having enhanced low permeability over time in containment applications. Of the many embodiments provided herein, one embodiment includes a method comprising: providing a bentonite barrier composition comprising: bentonite; and a polyanionic low molecular weight polymer; and forming a containment using the bentonite barrier composition to provide at least partial separation for a containment from its environment.
