ABSTRACT:
There is disclosed a composition which is useful, when added to soil, in containing water, said composition containing bentonite and a particular type of water-soluble polymer, the purpose of the water-soluble polymer being to decrease the amount of bentonite necessary to form a water containing enclosure made of soil. The amount of bentonite necessary in the present invention is at least 50% and, most often, 60% less than is necessary when no water-soluble polymer is present. The water-soluble polymer is preferably polyacrylic acid, water-soluble salts of polyacrylic acid, polymethacrylic acid, water-soluble salts thereof, and acylic copolymers formed from either acrylic acid or methacrylic acid. The invention also includes a method for containing water which includes admixing an effective amount of bentonite and water-soluble polymer with soil and forming a water-containing enclosure from said mixture.
