While Caesarstone is a very robust surface to begin with - stronger than both marble and granite in fact - there are simple measures you can take to ensure chipping doesn't occur.
Sharp non-radiused edge profiles should never be used. Caesarstone recommends a minimum radius of at least 3-4mm on any edge profile. The larger the radius, the more resistance the edge will have to impact.
If the benchtop incorporates an undermount sink, then the top edge of Caesarstone sink cut out must be a minimum radius of 6mm to minimise risk of chipping should a heavy pot hit this edge.
Ensure cupboards and drawers are installed correctly and don't make contact with the Caesarstone surface when opening and closing.
Take care to not drop heavy items onto a Caesarstone benchtop.
