    Abstract: Reactive geocomposite mats, and their method of manufacture, for treating contaminants in soil or water that allow the passage of essentially non-contaminated water therethrough. The geocomposite mat includes a pre-formed woven or non-woven geotextile, having a thickness of about 6 mm to about 200 mm, and having, a porosity sufficient to receive a powdered or granular contaminant-reactive material, contaminant-sorptive material, or a contaminant-neutralizing material (hereinafter collectively referred to as “contaminant-reactant material” or “contaminant-reactive material”) throughout its thickness, or in any portion of the thickness across its entire major surface(s). The powdered or granular contaminant-reactive material is disposed within the pores of the previously formed, high loft geotextile mat to surround the fibers, e.g., by vacuum or vibrating the high loft mat while in contact with the contaminant-reactive material to allow the powdered or granular contaminant-reactive material to flow by gravity into the pores of the previously formed geotextile and vibrational forces. Liquid-permeable cover sheets are adhered to the upper and lower major surfaces of the filled geotextile to prevent the powdered or granular material from escaping from the geotextile during transportation and installation.

    Abstract: Water-absorbent sheet material is manufactured by contacting a liquid-sorbent polymerization initiating substrate with polymerization catalyst and/or polymerization initiator, embedding the polymerization initiating sheet material with clay-containing slurry, and heating the embedded sheet material to polymerize the monomer and vaporize, to form a water sorbent polymer and to interlock the polymer and clay in the sheet material. Manufacture of water-absorbent sheet material comprises contacting a liquid-sorbent polymerization initiating substrate with a polymerization catalyst and/or a polymerization initiator to form a polymerization-initiating sheet material for a subsequently embedded monomer; embedding the polymerization initiating sheet material with a clay-containing slurry comprising water, clay, and polymerizable monomer to form a water-sorbent polymer; and heating the embedded sheet material to polymerize the monomer and vaporize at least a portion of the slurry water to form a water sorbent polymer and to interlock the polymer and clay in the sheet material. The slurry comprises less than 50% water. The weight ratio of monomer to clay is 1:19, throughout a portion of the thickness of the polymerization-initiating sheet material for intimate contact with the polymerization catalyst or polymerization initiator to initiate polymerization of the monomer.
