How does the thickness of granite slabs affect outdoor tree box durability?
The thickness of granite slabs plays a critical role in determining the durability of outdoor tree boxes. Thicker slabs, typically 2-3 inches, provide superior resistance to weathering, heavy foot traffic, and mechanical stress, making them ideal for high-traffic urban areas. Thinner slabs (1-1.5 inches) may be cost-effective but are more prone to cracking under pressure or extreme temperature fluctuations. Proper thickness ensures structural integrity, preventing moisture penetration and root damage. For long-lasting tree boxes, selecting the right granite thickness is essential to balance aesthetics, functionality, and longevity in outdoor environments.
