- 7. The invention as recited in claim 3, wherein the plurality of yarns projecting outwardly from the primary base have an average extended length above the primary base of about 0.6 inches.
- 8. The invention as recited in claim 1, wherein the pile layer has a standard pile density in the range of about 2000 to about 3000 ounces per cubic yard.
- 9. The invention as recited in claim 8, wherein the plurality of yarns projecting outwardly from the primary base have an average extended length above the primary base in the range of about 0.3 to about 0.9 inches.
- 10. The invention as recited in claim 1, wherein the average cumulative gap length between edges of adjacent modular surface covering elements is less than 0.05 centimeters.
- 11. The invention as recited in claim 1, wherein the modular surface covering elements are characterized by an average cumulative tuft overhang along all edges in the range of about 2.6 mm to about 5.4 mm as measured according to the procedure set forth in comparative example 14.
- 12. The invention as recited in claim 1, wherein the modular surface covering elements are characterized by an average seamability index of not greater than about 4 when measured according to the procedure set forth in comparative example 13.
- 13. The invention as recited in claim 1, wherein the modular surface covering elements are characterized by an average seamability index of not greater than about 3 when measured according to the procedure set forth in comparative example 13.
- 14. The invention as recited in claim 1, wherein the modular surface covering elements are cut from below the pile fabric face.
- 15. The invention as recited in claim 1, wherein said modular surface covering elements have at least one of a layer of tack, grip and adhesive adapted to adhere to said subfloor.
- 16. The invention as recited in claim 1, wherein said modular surface covering elements further comprise a layer of stabilizing material disposed at a position between the cushioning material and the pile fabric face.
- 17. The invention according to claim 16, wherein the stabilizing material comprises glass.
- 18. The invention as recited in claim 17, wherein the stabilizing material comprises a sheet of nonwoven glass.
- 19. The invention of claim 1, wherein said modular surface covering elements further comprise a load distributing layer disposed at a position between the cushioning material and the pile fabric face.
- 20. The invention as recited in claim 19, wherein the load distributing layer comprises a polymeric adhesive.
- 21. The invention as recited in claim 20, wherein said polymeric adhesive is a hot melt adhesive.
- 22. The invention as recited in claim 1, wherein said modular surface covering elements further comprise a load distribution layer comprising a tie coat material and a layer of stabilizing material disposed at a position between the cushioning material and the pile fabric face.
- 23. The invention as recited in claim 22, wherein the tie coat material is a resilient hot melt adhesive.
- 24. The invention as recited in claim 23, wherein the stabilizing material is glass.
