Cracking is generally not covered under the Caesarstone 25-Year Warranty​ as it typically occurs due to a fabrication or installation error, or as the result of mechanical stress and does not represent a fault in the Caesarstone product itself.
If a crack does occur, please contact the interior design company or stonemason who installed your bench top as they will be able to provide further assistance.
External factors which can contribute to cracking include:
Inadequate underbench support
Incorrect placement of cutouts and joins
Lack of consideration for thermal expansion, thermal shock or excessive heat
A severe impact
