Cracked Tile Corners (Tile)

Floor Detective® Claims and Conditions Guide

Summary

Cracked tile corners occur when fractures initiate at or near the corner of an individual tile and extend inward through the tile body. These fractures commonly develop where localized stress exceeds the tile’s ability to distribute load across its surface. Corner cracking is frequently associated with incomplete mortar support beneath tile corners, concentrated loading, substrate irregularity, or movement stress within the tile assembly rather than uniform failure of the tile material itself. Pattern distribution, fracture geometry, mortar support conditions, and loading relationship are important diagnostic indicators. Proper evaluation requires correlation of fracture behavior, substrate conditions, movement influence, and mortar-support characteristics before conclusions are formed.
