$Uni-Push - Bottom side fracture 1$

The bottom side of the end joint will fracture. This fracture will never be noticed by the installer when being installed. The upper portion will show a raised edge (as seen in other pictures). If the installer forced the edge back down the integrity of the joint will never remain stable and will ev...

Mechanical Joint Compromise (Resilient Plank)

Floor Detective® Claims and Conditions Guide

Summary

Mechanical joint compromise in resilient plank flooring refers to functional degradation, deformation, or partial structural weakening of the locking system without complete profile fracture. Click-lock systems rely on precise geometry to maintain engagement, transfer load, and resist separation. When installation force, disengagement stress, localized deflection, or cyclic loading alters the intended geometry, joint performance may be reduced even if no complete breakage is visible. Compromise may present as looseness, repeat gapping, clicking, vertical play, or progressive separation. Complete structural fracture of the locking profile is addressed separately under “Broken Locking Profiles / Profile Fracture.” The presence of joint compromise does not
