A modular flooring assembly including a flooring component adhered to a tray substrate is described. The modular flooring assembly may be interconnected with additional modular flooring assemblies to form a modular floor suitable for most flooring applications. The flooring component may be tile or wood or other materials commonly used in flooring applications. Convention fill-in grout or a snap-in grout may be used with the modular flooring assemblies. One suitable snap-in grout is a right angle grout member.

What is claimed: 1. A component of a flooring system comprising a flooring component, an adhesive, a tray substrate having a tray substrate surface which is an upward facing horizontal surface, a tray substrate bottom with a padding attached to the tray substrate bottom, a plurality of tray substrate vertical tray edges which protrude upward and extend around a perimeter of the tray substrate surface a plurality of tray substrate edges defining an outside perimeter of the tray substrate, the tray substrate edges having a plurality of upward tabs and downward tabs with the upward tabs and the downward tabs extending alternatively from the plurality of the tray substrate edges, wherein the upward tabs each have a convex surface and a valley, and the downward tabs each have a concave surface and a lip, wherein the flooring component is smaller than a tray surface defined by the tray substrate vertical edges and said flooring component is adhered to the tray substrate surface with the adhesive, further comprising a plurality of grout holders each having an angled shape that widens towards the bottom of the tray substrate, with the grout holders located between the altering upward tabs and downward tabs. 2. The component of a flooring system of claim 1 wherein the flooring component is selected from the group consisting of tile, stone, marble, wood, ceramic tile, porcelain tile, and granite. 3. The component of claim 1, wherein the tray substrate vertical tray edges run the entire perimeter of the tray substrate surface. 4. The component of claim 3, wherein the flooring component is selected from the group consisting of tile, stone, marble, wood, ceramic tile, porcelain tile, and granite. 5. The component of claim 1, wherein the upward and downward tabs have grout holes. 6. The component of a flooring system of claim 5, wherein the flooring component is selected from the group consisting of tile, stone, marble, wood, ceramic tile, porcelain tile, and granite. 7. The component of claim 5, wherein the tray substrate vertical tray edges run the entire perimeter of the tray substrate surface. 8. The component of claim 7, wherein the flooring component is selected from the group consisting of tile, stone, marble, wood, ceramic tile, porcelain tile, and granite. 9. The component of a flooring system of claim 1, wherein the flooring component is selected from the group consisting of tile, stone, marble, wood, ceramic tile, porcelain tile, and granite. 10.
