Abstract: A panel is provided forming a water barrier and comprising two opposing spaced sheets having between said spaced sheets a sealant composition comprising bentonite; a water soluble dispersing agent selected from the group consisting of a water-soluble salt of acetic acid, a water-soluble salt of phosphoric acid, and a water-soluble salt of boric acid; and a water-soluble polymer selected from the group consisting of polyacrylic acid, water-soluble salts of polyacrylic acid, hydrolyzed polyacrylonitrile, polyvinyl acetate, polyvinyl alcohol, copolymers of the foregoing, and a copolymer of acrylic acid and maleic anhydride, the amount of water-soluble polymer in said sealant composition being from 0.1% to 3.0%, by weight, and the amount of water-soluble dispersant in said sealant composition being from 0.1% to 3.0%, by weight, the weight ratio of water-soluble dispersant to water-soluble polymer being from 6:1-36.

Abstract: A soil stabilizing method by using an air bubbled solidifying suspension or solution, which is jetted into the ground at a high pressure for the formation of solidified soil having homogeneous strength.

Abstract: A composition and method for producing an improved lime-fly ash-aggregate is disclosed. The composition is prepared by mixing together lime, flyash, graded aggregate, adding water, and from 0.5 to 4 percent, based on total dry weight, of sludge from a water treatment plant. The mixture is placed on top of a prepared subgrade, spread uniformly, and compacted to a high degree of relative density to provide the main load-carrying component of a road, airport runway, parking lot or the like.
