Article Number
Condition
FINISHED FLOOR IS UNEVEN
Acceptable Performance/Condition
Applied finished flooring shall be installed without visible ridges or depressions. Where visible ridges or depressions occur, the variation shall not exceed 6 mm from the specified plane.
Warranty
One-Year - Work and Materials.
Ridges and depressions caused by normal shrinkage of materials are excluded from the statutory warranty.
Action
Visible ridges or depressions exceeding the acceptable condition shall be repaired.
Remarks
The homeowner must maintain finished flooring in accordance with manufacturer’s recommendations and prevent the accumulation of water on flooring.
When evaluating texture finishes in natural or manufactured floor tiles, the compared tiles shall be from the same room or defined area. Surface variations in natural or manufactured stone tiles are considered to be desirable characteristics of the product. However, when used on a floor or walking surface the variations should not be greater than 6 mm where they would constitute a trip hazard.
Variations in grout and/or flooring colour are to be expected when making repairs. For dye lot variations in ceramic floor tiles see Item 12.34.
For variations in colour in natural stone tile installations (granite, marble, travertine, slate and limestone) see Item 12.35.

For additional details on how the variation is measured, please see Appendix A4 - Measuring Variation from the Specified Plane.
