Cracks in Grout and breaking away in pieces

Cracks in Grout - I RESENTLY HAD CERAMIC TILE INSTALLED AND I NOW HAVE THE GROUT BREAKING AWAY IN PIECES AROUND SOME TILES.I ALSO HAVE ALOT OF FINE CRACKS IN THE GROUT.WHAT IS THE PROBLEM AND HOW CAN I FIX IT?

ANSWER – Cracking grout is a symptom that there is excessive movement in the tile. The excessive movement could be caused by too much deflection within the floor. The industry standard is that the deflection of a floor should not exceed 1/360. If the tiles are not attached properly and are hollow that could also cause the cracking grout too. The first thing to do is determine what the problem is and then you will be able to determine the remediation options to repair the floor. CTaSC does provide installation failure inspections throughout the USA. Please visit  www.CTaSC.com for more information.

Good Luck!
