Abstract

Cushion backed carpet tiles and carpet tile installations which can be installed without adhesives are described. The carpet tiles are manufactured according to rigid specifications in order that no corner of any of the individual tiles is 1/16″ or greater off the floor due to curl, and no corner on the tile has cup of greater than 3/16″. In this way, a substantially to entirely adhesive-free carpet tile installation can be achieved, with the installation being capable of withstanding the rigors of a variety of typical types of wear, such as rolling traffic, etc., without shifting or snowplowing over adjacent tiles.

Claims (17)

1. A method of laying no adhesive cushion backed carpet tile on to a surface, comprising the steps of:

a) reversibly securing at least one indicator carpet tile to said surface with a securing device or means;

b) placing a second carpet tile on said surface wherein said second carpet tile and said indicator carpet tile abut;

c) placing a third carpet tile on said surface wherein said third carpet tile abuts at least one of said indicator carpet tile and said second carpet tile;

d) placing at least one subsequent carpet tile on said surface wherein said subsequent carpet tile abuts at least one of said indicator carpet tile, said second carpet tile and said third carpet tile;

e) removing said indicator carpet tile and removing said securing device or means; and

f) replacing said indicator tile or a carpet tile in a location vacated by said indicator carpet tile.

2. The method of laying no adhesive cushion backed carpet tile of claim 1 wherein said third carpet tile abuts said second carpet tile.

3. The method of laying no adhesive cushion backed carpet tile of claim 1 wherein said third carpet tile abuts said indicator tile.

4. The method of laying no adhesive cushion backed carpet tile of claim 1 wherein said subsequent carpet tile abuts said indicator tile.

5. The method of laying no adhesive cushion backed carpet tile of claim 1 wherein said subsequent carpet tile abuts said second carpet tile.

6. The method of laying no adhesive cushion backed carpet tile of claim 1 wherein said subsequent carpet tile abuts said third carpet tile.

7. The method of laying no adhesive cushion backed carpet tile of claim 1 wherein said subsequent carpet tile abuts said indicator carpet tile and said third carpet tile.

8. The method of laying no adhesive cushion backed carpet tile of claim 1 wherein said indicator tile is placed in substantially the center of the surface.

9. The method of laying no adhesive cushion backed carpet tile of claim 1 further comprising the step of repeating said step of placing additional subsequent carpet tile until said surface is substantially covered.

10. The method of laying no adhesive cushion backed carpet tile of claim 1 wherein each of said cushion backed carpet tile has a cup of about 3/16″ or less and a curl of about 1/16″ or less.

11. The method of laying no adhesive cushion backed carpet tile of claim 1 further comprising the step of treating said surface to enhance the coefficient of friction thereof.
