Claims24
An engineered waterproof plank comprising:
- (a) a veneer layer adhered to a top surface of a waterproof core, wherein the veneer layer is selected from the group consisting of wood veneer, cork veneer, bamboo veneer, tile veneer, stone veneer, rubber veneer, decorative plastic veneer, linoleum veneer and decorative vinyl veneer
- (b) a first waterproof adhesive layer bonding the veneer layer to the top surface of the waterproof core;
- (c) the waterproof core comprising an extruded dust and plastic composite;
- (d) the plank having a first edge with a groove extending laterally into the waterproof core and a second opposite edge with a lateral protrusion from the waterproof core, wherein the groove and protrusion have profiles shaped to form a click-lock edge fastening system.

An engineered rectangular waterproof plank comprising:
- (a) a veneer layer of decorative vinyl adhered to a top surface of a waterproof core by a hot melt adhesive;
- (b) a cover layer over the veneer layer, said cover layer selected from the group consisting of melamine resin with aluminum oxide and polyurethane;
- (c) an underlayer selected from the group consisting of cork, rubber and foam, said underlayer adhered to a bottom surface of the waterproof core by a hot melt adhesive;
- (d) the waterproof core comprising an extruded dust and plastic composite, said waterproof core having substantially planar top and bottom surfaces separated by a thickness defining a first edge along a first side and a second edge along an opposite second side, and third and fourth edges along opposite third and fourth sides, wherein the first edge has a groove extending laterally into the waterproof core and the second opposite edge has a lateral protrusion from the waterproof core, the groove and protrusion having profiles shaped to form a click-lock edge fastening system.

An engineered rectangular waterproof plank comprising:
- (a) a veneer layer selected from the group consisting of cork veneer, bamboo veneer and wood veneer, said veneer layer encapsulated in resin, and said veneer layer adhered to a top surface of a waterproof core by a hot melt adhesive;
- (b) an underlayer selected from the group consisting of cork, rubber and foam, said underlayer adhered to a bottom surface of the waterproof core by a hot melt adhesive;
- (c) the waterproof core comprising:
- (i) at least about 55% of dust selected from the group consisting of wood, bamboo and cork and a combination of two or more of wood, bamboo and cork;
- (ii) at least about 20% of high-density polyethylene;
- and
- (iii) calcium carbonate filler;
- (d) said waterproof core having substantially planar top and bottom surfaces separated by a thickness defining an edge along opposite first and second sides, and along opposite third and fourth sides, wherein a groove extends laterally into the waterproof core along the first edge and a lateral protrusion extends from the opposite second edge of the waterproof core, the groove and protrusion comprising a click-lock edge fastening system.
