Repairs and problems
Grout cracking along the same line repeatedly
How this is diagnosed
- Wall-to-floor and internal corners need a flexible sealant joint
- because rigid grout cannot accommodate the movement there.
- Cracking across the middle of a tiled floor
- suggests deflection or a missing decoupling layer under the tile.
Common mistakes to avoid
Wall-to-floor and internal corners need a flexible sealant joint, because rigid grout cannot accommodate the movement there.
Common questions
Is cracked grout letting water through?
Potentially, especially in a shower, it should be dealt with rather than watched.
Can I just fill it?
Only after understanding why it moved; otherwise it reopens.
