07 Assessment
Advantages
- Exceptional durability (50+ years lifespan with proper maintenance)
- High thermal mass for passive heating/cooling
- Low maintenance requirements
- Slip-resistant surface (especially at lower grit levels)
- Customisable appearance through grit selection
- No VOC emissions from finished surface
- Fire resistant (non-combustible)
- Termite and pest resistant
- Suitable for all Australian climate zones
- Can be repolished to restore appearance
- Compatible with hydronic heating systems
- Cost-effective over lifecycle
Constraints
- High initial installation cost ($50-100/m²)
- Cold underfoot without heating in cool climates
- Hard surface (uncomfortable for prolonged standing)
- Can crack if substrate moves or settles
- Requires professional installation
- Limited acoustic absorption (NRC 0.03-0.05)
- High embodied carbon (240-385 kg CO₂e/m³)
- Cannot be easily modified after installation
- Susceptible to staining if not sealed properly
- Thermal mass can work against comfort if poorly designed
