What are the most common issues related to cracking in terrazzo countertops, and how can they be avoided?

Terrazzo countertops are prized for their beauty and durability, but they can develop cracks due to various factors. Understanding these issues and implementing preventive measures is crucial for maintaining their longevity and appearance.

The most common causes of cracking include structural movement in the building, improper installation techniques, insufficient substrate support, thermal stress from sudden temperature changes, and impact damage from heavy objects. Hairline cracks often appear first around stress points like edges, corners, or cutouts for sinks.

To prevent these issues, ensure proper installation by experienced professionals who use adequate reinforcement and appropriate expansion joints. The substrate must be perfectly level and strong enough to support the terrazzo's weight. Regular maintenance including proper sealing every 1-2 years creates a protective barrier against moisture and stains. Avoid placing extremely hot items directly on the surface and use cutting boards to prevent impact damage. Address any minor cracks immediately with professional epoxy resin repairs before they expand.

With proper installation, routine care, and immediate attention to any damage, terrazzo countertops can remain beautiful and crack-free for decades, making them a worthwhile investment for any kitchen or bathroom.
