Steps – Performance Issues (Carpet)

Floor Detective® Claims and Conditions Guide

Summary

Carpet installed on steps is subjected to concentrated traffic, repeated flexing, and compressive loading conditions that exceed typical flat-floor use. Stair traffic places repeated compressive, shear, and bending forces on treads and nosing edges, accelerating crushing, matting, soiling, and visible appearance change compared to adjacent level surfaces. Performance on stairs is commonly reduced because traffic is concentrated into narrow travel paths and repeated pivot areas. The condition primarily affects appearance retention and texture uniformity rather than structural serviceability. See also Crushing, Matting, Soiling, and Carpet Problems for broader context.
