Laminated countertop assembly

A laminated countertop assembly comprising:

• a first generally longitudinal slab including
• a first substrate;
• lamination on a countertop side of the first substrate;
• lamination on an edge side of the first substrate at least generally perpendicular and adjacent to the countertop side of the first substrate, the lamination on the edge side of the first substrate extending along a first portion of a length of the edge side of the first substrate;
• a first miter cut angled into the first substrate from where the laminated first portion of the edge side of the first substrate meets an unlaminated second portion of the edge side of the first substrate;
• and
• a first plurality of slots extending into the first substrate along the second portion of the edge side of the first substrate, each one of the first plurality of slots for receiving a biscuit;
• and
• a second generally longitudinal slab configured to abut the first generally longitudinal slab, the second generally longitudinal slab including
• a second substrate;
• lamination on a countertop side of the second substrate;
• lamination on an edge side of the second substrate at least generally perpendicular and adjacent to the countertop side of the second substrate;
• a second miter cut at a corner of the second substrate where the laminated edge side of the second substrate meets an unlaminated end side of the second substrate, the second miter cut configured to abut the first miter cut;
• and
• a second plurality of slots extending into the second substrate along the unlaminated end side of the second substrate, each one of the second plurality of slots for receiving a biscuit, the first plurality of slots and the second plurality of slots aligned for receiving a plurality of biscuits to register the first generally longitudinal slab and the second generally longitudinal slab together at an interface between the unlaminated second portion of the edge side of the first substrate and the unlaminated end side of the second substrate, wherein the first substrate defines a radius at an interface between the first miter cut and the unlaminated second portion of the edge side of the first substrate, and the second substrate defines the radius at an interface between the second miter cut and the unlaminated end side of the second substrate.

A method of forming a laminated countertop assembly, the method comprising:

• forming a first substrate;
• laminating a countertop side of the first substrate;
• laminating an edge side of the first substrate at least generally perpendicular and adjacent to the countertop side of the first substrate so that the lamination on the edge side of the first substrate extends along a first portion of a length of the edge side of the first substrate;
• angling a first miter cut into the first substrate from where the laminated first portion of the edge side of the first substrate meets an unlaminated second portion of the edge side of the first substrate;
• forming a first plurality of slots extending into the first substrate along the second portion of the edge side of the first substrate, each one of the first plurality of slots for receiving a biscuit;
• forming a second substrate;
• laminating a countertop side of the second substrate;
• laminating an edge side of the second substrate at least generally perpendicular and adjacent to the countertop side of the second substrate;
• angling a second miter cut at a corner of the second substrate where the laminated edge side of the second substrate meets an unlaminated end side of the second substrate, the second miter cut configured to abut the first miter cut;
• forming a second plurality of slots extending into the second substrate along the unlaminated end side of the second substrate, each one of the second plurality of slots for receiving a biscuit, the first plurality of slots and the second plurality of slots aligned for receiving a plurality of biscuits to register the first generally longitudinal slab and the second generally longitudinal slab together at an interface between the unlaminated second portion of the edge side of the first substrate and the unlaminated end side of the second substrate;
• and
• forming a radius in the first substrate at an interface between the first miter cut and the unlaminated second portion of the edge side of the first substrate, and forming the radius in the second substrate at an interface between the second miter cut and the unlaminated end side of the second substrate.
