Abstract: Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non-woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.

Abstract translation: 本发明描述了能够提供高导电性水（例如海洋水）的屏障的地层复合材料及其制造方法，用于防止与高导电性水接触的表面。 地层复合制品垫包括在其整个主表面上含有粉末或颗粒部分交联的丙烯酰胺/丙烯酸酯/丙烯酸共聚物的织造或非织造土工织物片或垫。 当用高电导率水（如海洋水）进行水合时，粉末或颗粒状共聚物具有出乎意料的高自由膨胀性。 将不透液性覆盖片粘附到填充的共聚物承载土工织物的上主表面上，以提供初级高导电性阻水层，如果破裂，则通过不溶于水的下层的膨胀而被密封，部分交叉 连接的丙烯酰胺/丙烯酸共聚物。

Abstract: A composition capable of increased impermeability against the passage of ionic liquids therethrough can include a clay mixed with an anionic and cationic polymer. Such compositions can be provided in geosynthetic liners to provide a hydraulic barrier in aggressive leachate environments.

Abstract: A hydraulic barrier composition can include granules of a water-swellable clay and a water-soluble 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.
