A simple way to check for the sound in question is to tap on the tiles with a hard object such as a steel ball bearing. Chains or special sounding devices can be used for larger areas. If the tile is well bonded (i.e. attached to the concrete substrate), it will have a high-pitched sound.

Should hollow tiles be replaced?

ANSWER. ANSWER - Hollow sounding tile is not a defect per industry standards. Although a hollow sounding tile can be a symptom of a defect. If all of the floor sounds hollow or a portion of the floor sounds hollow, then it might be due to the materials and configuration of the tile assembly below.

Why does my ceramic tile sound hollow?
