Claims19
An engineered waterproof plank comprising:
- (a) a veneer layer adhered to a top surface of a rigid waterproof core, wherein the veneer layer is selected from a 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 waterproof adhesive layer bonding the veneer layer to the top surface of the rigid waterproof core;
- (c) the rigid waterproof core comprising a plastic composite;
- (d) the engineered waterproof plank having a first edge with a groove extending laterally into the rigid waterproof core and a second opposite edge with a tongue extending from the rigid waterproof core;
- wherein the plastic composite further comprises a plastic and an additive, said additive selected from a group consisting of anti-UV agents, anti-oxidation agents, stabilizers, colorants, anti-fungus agents, coupling agents, reinforcing agents, and lubricants.
