Title: HYDRAULIC BARRIER COMPOSITION AND METHOD OF MAKING THE SAME
Abstract:
A hydraulic barrier composition can include granules of a water-swellable clay and a water-solvatable polymer. Upon contact with a leachate at least portion of the polymer is solvated by the leachate and becomes entrapped in at least one of clay pores, at clay platelet edges, and between adjacent platelets.
