Abstract: A water-swelling composition adapted to be secured to an area of potential water flow in the form of a flexible cohesive mass comprising about 10% to about 90% by weight of a water-swellable layered material; about 1% to about 30% by weight of an elastomer; about 8% to about 65% by weight of a material selected from the group consisting of polypropene, polybutene, and a mixture thereof; and about 0.1% to about 20% by weight of a clay binder selected from group consisting of (1) an onium ion-liberating compound that is ion-exchanged with platelet cations of the layered material, (2) a coupling agent that is reacted with the layered material, and (3) a combination thereof.
Abstract: A waterproofing article in the form of rod-, or rope-shaped clay-containing compositions, and a method of waterproofing using the article, whereby a water-penetrable, degradable, or water-soluble film or coating forms an outer surface of the article for avoiding premature hydration of an underlying clay-containing composition. In the preferred embodiment, an inner core of a water-swellable clay-containing composition includes a coating of a water-removable or degradable material, completely encasing the major outer surfaces of the composition, having controlled, predetermined water-penetration; high pH degradability; or water-solubility so that the core of water-swellable clay-containing composition is quickly hydrated after water-penetration of the coating material, and to prevent clay hydration during installation, prior to water-penetration of the coating material.

Abstract: A tool packaging system of complementary plastic planar members snapfit together and interlocked therebetween to allow a planar assembly or a configuration akin to a toolbox. In an alternative embodiment, complementary extruded plastic planar members may be slidably engaged and snapfit to provide either a planar assembly, or rectangular prism assembly which is completed by snap-fitting end caps thereto.
