Considerations
Darker granite colors can absorb and retain significant heat in direct sunlight, making surfaces hot. It is a heavy material, requiring substantial effort and equipment for installation, which can increase costs.
Stone × Application
Granite — landscape
Granite is exceptionally durable and weather-resistant, making it ideal for various landscape applications such as paving, curbing, steps, and decorative elements. It resists scratching, fading, and staining, ensuring longevity.
Specifications
- Finish: Flamed, Bush-hammered, or Natural Split finishes are highly recommended for landscape applications to provide excellent slip resistance and a natural, rugged aesthetic that blends well with outdoor environments.
- Thickness: 3 cm to 5 cm for pavers, stepping stones, and curbing to ensure durability and stability. Larger blocks for decorative elements can vary greatly in size.
- ASTM: ASTM C615/C615M (Standard Specification for Granite Dimension Stone). Freeze-thaw resistance (ASTM C666/C666M) and water absorption (ASTM C97/C97M) are critical for outdoor applications. DCOF testing is essential for paved areas.
- Maintenance: Low (requires minimal cleaning to remove debris. Sealing is generally not critical for most landscape applications).
- Installed: $40-$150/sq ft for paving; $100-$5000+ for custom elements (costs vary widely based on granite type, size, and complexity of the landscape feature).
