ABSTRACT:
A flexible or rigid panel, and method of making the panel, useful as a water barrier including an intermediate layer of a water-swellable colloidal clay, such as pentonite, sandwiched between two layers of sheet material, such as woven or non-woven fabric, or paperboard, wherein at least one one of the sheet material layers has a water-soluble coating material covering substantially the entire outer surface of the sheet material layer. The water-soluble coating is a material that dissolves upon a predetermined water contact period, having a controlled, predetermined water-solubility so that the intermediate water-swellable clay layer is protected against hydration during installation.
