Ceramic, porcelain and natural stone: how tile floors handle flooding
Tile is often the most flood-tolerant flooring in an Auckland home, but the tile body, the grout joints and the layers beneath behave very differently once water arrives. Knowing the material changes what recovery looks like.
How flood outcomes differ across ceramic, porcelain and natural stone, and why the grout and the substrate usually decide the result.
Tile is often the most flood-tolerant flooring in an Auckland home, but the tile body, the grout joints and the layers beneath behave very differently once water arrives. Knowing the material changes what recovery looks like.
Identify the tile type - glazed ceramic and porcelain resist absorption; natural stone and unglazed tile drink water.
Treat grout lines and tile edges as the entry points - the tile face is rarely the problem.
Judge the floor by what is under it - a sound tile over a saturated substrate is not a recovered floor.
