Some of the 16" square tiles have hollow sound when tapped. Apparently the thinset was improperly set. Builder says easily fixed, will drill holes in grout and force agent into hollow to repair. I am a little skeptical, is this a reasonable solution or just expedient? Seems like the thinset might be good on the periphery of the tile and inhibit the new agent flowing into the hollow. Thank you, Seamus J. Wilson
