Crack on tile floor

Hi All,

I have cracks on my tiles all over my living room. My property is 20 years old. I am worried if these cracks are because of the age of tiles or a structural issue. I am looking for a recommendation on whom to contact to get this checked in Brisbane.

 

Are they drummy ? ie sound hollow when gently tapped with a coin ? If so the tiles arent bonded to the floor and this small gap means when you walk on them they cracked.

 

what kind of property is it ? apartment ? house with concrete floor ? or the standard house with timber joist underneath ?

 

Thanks for the reply.. These tiles don't sound drummy when tapped. My property was build in 1998 iand is house with concrete floor..It's not a Queenslander..

 

Engineer time. Movement ?

 

Ya I was also thinking the same.. I wanted to check if I should call a builder inspector or a structural engineer ?

 

The way the cracks run neatly across tile edges suggests a problem with the slab.
