ABSTRACT:
A bentonite composition useful for preventing a flow of water through a structure is disclosed. The composition has substantially all of the bentonite in non-hydrated form by dispersing the bentonite throughout a non-aqueous gel formed from a non-aqueous liquid and a suitable gelling agent for the liquid to form a cohesive mass capable of adhering to a structure while maintaining a desired, cohesive form. The composition can be made into sheets, rods, tubes and the like. For example, the composition can be applied to one side of a water permeable cellulosic fiber containing sheet and the composition side of the sheet secured over an area of potential water flow.
