Tile Installation Failures
Tile installation is one of the most technically demanding flooring trades. When installation standards are not followed, failures can appear within months or even weeks. Common tile installation failures include hollow sounds, cracking, lippage (uneven tile edges), loose tiles, and grout problems — all of which can be diagnosed by a certified tile inspector.
Key Takeaways
- Insufficient thinset coverage (below 80% interior / 95% wet areas) is the most common defect
- Lippage — uneven adjacent tile edges — results from poor installation technique or incorrect trowel selection
- Missing or inadequate expansion joints causes stress cracking
- Installing large-format tile without back-buttering leaves air voids and weak bonds
- A certified inspection references ANSI A108, TCNA Handbook, and manufacturer specifications
Frequently Asked Questions
Not always — some hollow sound at tile edges is acceptable. But widespread hollow tile or hollow sounds at tile centers indicate a significant installation defect under ANSI standards.
