Moisture impervious panel
First Claim
1. A deck structure comprising first and second adjacent panels each panel comprising a pair of spaced facing sheets interconnected by a central rigid, non-biodegradable, corrugated support sheet forming a plurality of voids between the central rigid sheet and respective ones of the facing sheets, and a mixture of water-swellable bentonite and a compressible filler substantially filling said voids;
- and a wear surface covering the top faces of said first and second panels, said top faces being water penetrable;
said central, rigid, non-biodegradable, corrugated support sheets of said first and second panels overlapping in mating contact.

Abstract
A moisture impervious panel includes a pair of spaced facing sheets interconnected by a central rigid support sheet, such as corrugated fiberglass, to form a plurality of pockets between the support sheet and the facing sheets. The pockets are filled with a composition of water-swellable bentonite and a compressible filler, such as vermiculite.

5. A method of rendering a surface water impermeable comprising, disposing on said surface a plurality of moisture impervious panels, interconnected by a central, rigid, non-biodegradable, corrugated support sheet, each panel comprising a top sheet of a water penetrable material spaced apart from a bottom sheet, said top sheet interconnected to said bottom sheet by said central, rigid, non-biodegradable, corrugated support sheet, said support sheet forming a plurality of voids between the support sheet and both the top sheet and the bottom sheet, and a mixture of water-swellable bentonite and a compressible filler substantially filling said voids;
- and disposing a wear surface on the top sheet of said panels.

8. A method of forming a water-impermeable deck structure comprising filling voids in first and second panels with a mixture of water-swellable bentonite and a compressible filler, each panel comprising a pair of spaced facing sheets, including an uppermost water penetrable facing sheet, interconnected by a central, rigid, non-biodegradable, corrugated support sheet at least one of said facing sheets of each panel disposed to incompletely cover said corrugated central support sheets;
- interconnecting said panels by disposing an uncovered portion of the corrugated sheet of said first panel over an uncovered corrugated portion of said second panel such that the central, rigid, non-biodegradable corrugated sheets of said first and second panels are in direct contact along said uncovered portions to provide a mixture of water-swellable bentonite and a compressible filler above and below the contacting portions of said support sheets and disposing a wear surface on the top sheet of said panels.
