But how stiff is stiff enough.
How to keep floor tiles from cracking.
How to prevent cracked tile.
Even the hardest tile will crack if a wood framed subfloor deflects too much under load.
However there are steps you can take mitigate tile cracking.
Generally hairline cracks in the concrete will not present an issue to the tile floor above.
This will prevent formation of cracks in the concrete which lead to reflective.
This is known as reflective cracking and it can be easily prevented by adding a crack isolation membrane during installation.
Cracked tile is usually a sign of poor preparation of the substrate.
Take these precautions to prevent tile cracking in the future.
Cracked tiles on floors and walls is a problem because it can be difficult to track down the source of the crack.
For a concrete subfloor the most effective thing to do is add steel reinforcing bars when the concrete slab is poured.
Crack isolation membranes allow for slight shifts or movement of the floor that lies underneath the tile allowing it to move independently without moving and cracking the tiles above it.
However cracks wider than 1 8 inch will eventually transfer to the tile it notes.
But the brittle nature of tiles and the constant foot traffic means that the tiles are likely to crack at some point.
In far more instances the crack was caused by anomalies under or around the tile.
Are you planning to have new tile floors installed.
