When a tile sounds hollow, the noise is often the first sign of an adhesion problem with the substrate. This can happen on floors or walls,
whether recent or old, and should not be underestimated: intervening correctly helps avoid more extensive detachment and damage to the rest of the surface.
Why do tiles sound hollow?
The "hollow" sound indicates that a non-adherent space has been created between the tile and the subfloor. The most common causes are
an uneven application of the adhesive, movement of the screed, structural settling, or variations in temperature and humidity. In some cases, the problem can
emerge even long after installation, especially if the substrate was not perfectly stable or if materials unsuitable for the intended use were used.
Evaluating the extent of the problem
Before taking action, it is important to understand if the phenomenon concerns a single tile or a larger area. If the hollow sound is localized and the tile appears
intact and well-aligned, the problem can be resolved with a targeted intervention. If, on the other hand, several tiles are affected, it could be an installation
defect or an inadequate substrate, requiring a more in-depth evaluation.
When it is possible to intervene without removing
In the presence of limited voids, it is possible to consolidate the tile without dismantling it by using injections of specific materials that fill the space below
and restore adhesion to the substrate. This solution reduces the impact of the intervention and keeps the existing covering intact, provided that the subfloor is structurally sound.
When it is necessary to replace the tile
If the void is extensive, if the tile has cracks, or if the substrate is compromised, the most effective solution is to remove the tile and restore the base before
a new installation. Intervening only on the surface, in these cases, might not be enough and could lead to the recurrence of the problem over time.
Preventing the problem with correct installation
Prevention remains essential: installation performed with appropriate adhesives, correct glue distribution, and well-prepared substrates drastically reduces
the risk of tiles sounding hollow. Choosing the right material, based on thickness and intended use, also contributes to the stability of the floor or wall covering.
Intervening with judgment to preserve the surface
Addressing the problem of tiles sounding hollow requires a careful evaluation of the causes and the condition of the substrate. The variety of floor tiles, wall tiles
and solutions from Ceramiche Dordini allows for the consideration of surfaces suitable for correct and lasting installation, favoring restoration work or new installations that are more stable over time.
