Abstract
Abstract In a method for installing tiles on a substrate, tiles, having a first surface and a second, machinable surface, are arranged in installed locations on the substrate with the second, machinable surface facing away from the substrate. The machinable surfaces are then machined to reduce tile-to-tile irregularities and adjust for the variations in the subfloor, and the tiles are turned over so that the first surfaces face away from the substrate. A decorative flooring unit is also provided having a tile with a shim layer on its underside, an edge member surrounding the tile and a substrate extending beneath the edge member and the tile. The tile is installed within the edge member with the shim layer facing away from the substrate. The tile may be reversed after sanding the edge member and shim layer.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
114 words
A method for installing tile units on a subsurface, comprising: providing a plurality of tile units, each tile unit having a substantially planar first surface and a substantially planar second, machinable surface; arranging each of said plurality of tile units in installed locations with respect to the subsurface, such that said second, machinable surfaces face away from the subsurface; machining said second, machinable surfaces so as to reduce tile-to-tile irregularities in height from said subsurface; and turning over each of said plurality of tile units so that said second, machinable surfaces face said subsurface and said first surfaces face away from said subsurface, whereby tile-to-tile irregularities in heights of said first surfaces are reduced.
Claim 2
Independent Claim
114 words
A method for installing tile units on a subsurface, comprising: providing a plurality of tile units, each tile unit having a substantially planar first surface and a substantially planar second, machinable surface; arranging each of said plurality of tile units in installed locations with respect to the subsurface, such that said second, machinable surfaces face away from the subsurface; machining said second, machinable surfaces so as to reduce tile-to-tile irregularities in height from said subsurface; and turning over each of said plurality of tile units so that said second, machinable surfaces face said subsurface and said first surfaces face away from said subsurface, whereby tile-to-tile irregularities in heights of said first surfaces are reduced.
Claim 3
Dependent Claim
44 words
The method as claimed in claim 1, wherein each of said tile units of said providing step comprises a decorative layer bonded to a shim layer, said first surface being on said decorative layer and said second, machinable surface being on said shim layer.
Claim 4
Dependent Claim
14 words
The method as claimed in claim 2, wherein said decorative layer is natural stone.
Claim 5
Dependent Claim
29 words
The method as claimed in claim 2, wherein said decorative layer is selected from the group consisting of ceramic tile, wood, metal, plastics, vinyl, glass, terra cotta and carpeting.
Claim 6
Dependent Claim
28 words
The method as claimed in claim 2, wherein said shim layer is selected from the group consisting of plywood, particle board, medium density fiberboard, fiberboard, and cement board.
Claim 7
Dependent Claim
73 words
The method as claimed in claim 2, wherein said step of providing a plurality of tile units further comprises: providing a substantially planar reinforcement component for reinforcing the decorative layer; elongating said reinforcement component in a plane of said reinforcement component; bonding said elongated reinforcement component to said decorative layer; bonding said shim layer to said reinforcement component; and releasing said elongation of said reinforcement component, thereby placing said decorative layer in compression.
Claim 8
Dependent Claim
17 words
The method as claimed in claim 1, wherein said machining step comprises sanding said second machinable surfaces.
Claim 9
Dependent Claim
25 words
The method as claimed in claim 1, further comprising the step of securing the tile units to the subsurface after turning the tile units over.
Claim 10
Dependent Claim
23 words
The method as claimed in claim 1, wherein said machining step is selected from the group consisting of grinding, polishing, planing and milling.
Claim 11
Dependent Claim
70 words
The method as claimed in claim 1, further comprising the steps of: providing a plurality of edge components having front surfaces and back surfaces; arranging said plurality of edge components in installed locations with respect to the subsurface, such that said front surfaces face away from the subsurface; and machining said front surfaces of said edge components to diminish irregularities in height between said tile units and said edge components.
Claim 12
Dependent Claim
64 words
The method as claimed in claim 10, wherein the step of providing a plurality of edge components comprises providing an edge component surrounding each said tile unit, said tile units being removably assembled within said edge components with said second, machinable surfaces of said tile unit facing in a direction corresponding to a direction in which said front surfaces of said edge components face.
Claim 13
Dependent Claim
42 words
The method as claimed in claim 10, wherein said step of providing said tile units further comprises providing a substrate component disposed beneath said tile unit and said edge component, said back surface of said edge component being attached to said substrate.
Claim 14
Dependent Claim
44 words
The method as claimed in claim 12, wherein said substrate is offset from said edge component to provide overlapping edges, and said step of arranging said plurality of tile unit includes overlapping said edges of said tile units with edges of adjacent tile units.
Claim 15
Dependent Claim
42 words
The method as claimed in claim 1, wherein said step of providing said tile units further comprises providing a removable, protective covering over said first surface, and further comprising the step of removing said protective covering after turning over said tile units.
