Many clients come to us with pictures of they're kitchen countertops cracked from moister from inside. This mostly always happens when the calking from the kitchen sink isn't fully stopping the water from entering the granite. When this happens moister enters the metal rod inside the stone making it crack. Good news, We can fix it! What we do first is get the metal rod out of there (it can happen again if we don't) Secondly we grind down the granite to make it flush. We fill the crack with color matching epoxy and re-sand it down again and give it the finish. The final step would be sealing it and its easy as that. With 20+ years of experience we assure you the best outcome for your stone. Thank you for reading.
