QUESTIONThe fabricator has installed granite countertops that are cracked all the way through and along the counter. They are saying that is normal because it’s such a delicate stone. Can you please advise me?
ANSWERANSWER - The Natural Stone Institute, formally the Marble Institute of America, Dimension Stone Design Manual states that "Cracks occur in stones as a result of man-made mechanically induced stresses during handling, fabrication, transport, or installation."
When cracks are detected prior to fabrication in slab material with lesser soundness properties, it is common practice to repair the cracks by cementing them together with epoxy or a polyester resin, either with or without dowel reinforcement. Although the repaired cracks should not be noticeable.
