Underlayments are the support materials that lay underneath your tile on a floor. They provide a water-stable base, make the floor more rigid (less chance of cracked tiles), and are better suited for tile adhesion. A well-set tile on a sturdy underlayment should never crack, and will last for decades.
People also ask, what is the best underlayment for tile floors?
Exterior plywood is an acceptable underlayment for tile and is preferred to interior-grade plywoods because the bonding adhesives used are waterproof. If water seeps through the tile installation to the underlayment, it will not cause the wood to swell, as happens with interior-grade plywood.
Furthermore, do you have to use durock under tile? In short, tile and grout are not inherently waterproof. Cement backer board is often used as a tile base on plywood or OSB subfloor. Cement backer board on concrete as a subfloor or underlayment is usually not recommended or needed. In most cases, you can apply tile directly to the concrete.

Can I put tile directly on subfloor?
While you can lay tile directly over a concrete slab using thin-set adhesive, don't make the mistake of applying tile directly to a plywood subfloor. No matter how firm the subfloor; the plywood will expand and contract at a different rate as the tile, causing cracks to develop in the grout lines or tiles over time.Can you lay tile directly on concrete?
While you can install tile directly on concrete, problems erupt when the concrete cracks or shifts. All of the movement in concrete is transferred to the tile. Cracks in concrete immediately become cracks in the tile.How thick should cement board be for tile?
