An easy DIY way to test if your floor tiles are hollow or drummy, is to give them a light knock or tap. You can use the handle of a screwdriver or lightly tap with a coin a ball bearing. However, please ensure you never tap the tiles too hard, especially if you think they are hollow underneath. As tapping too hard may lead to chipping or cracking of the tile.

Usually people will notice the echoing or hollow sound coming from their tiles in high traffic areas. This is usually first noticed from walking on the tiles in shoes.

Why Is This Happening?

Here we have listed the main reasons (we find), why people have hollow sounding floor tiles:

    • There was not sufficient adhesive applied to the tiles when they were first laid. Floor tiles should have full coverage upon initial installation. We find many floors have only been spot fixed, leaving huge voids between the substrate and tile
    • The tile and adhesive have debonded or separated from the substrate creating the void
    • The tile has debonded from the adhesive and the substrate creating the void
    • Movement in the slab or substrate
    • Water damage such as flooding
    • Lack of or no expansion joints used, causing pressure amongst the tiles. This pressure can lead to tiles not only debonding but floor tiles popping and buckling.
