Cracked tiles after skipping expansion joints: Mandatory or overkill?
Last month, I installed porcelain tile in a 400 sq ft living room without expansion joints, thinking it was overkill for a climate-controlled space. Three weeks later, hairline cracks appeared along the grout lines. Some guys in my crew say expansion joints are non-negotiable, even indoors, to handle substrate movement. Others argue that with proper underlayment and adhesive, it's fine to omit them in residential settings. I'm torn because the repair cost me a full day's labor and materials. What's your stance? Have you seen similar failures, or do you think I just got unlucky?

Expansion joints saved my redo, so I always include them now.

Wow, @david_young, glad to hear expansion joints worked for you. In my experience, they're crucial for accommodating movement in concrete. What type of project were you doing that made them so essential?

Absolutely! Saved my garage slab too (learned from past mistakes).

Our last warehouse pour (joints saved us from a total crack disaster).

Man, reminds me of the basement floor I poured years back without proper joints. Cracked like a dried riverbed, should have listened to @david_young's advice sooner.
