07 Assessment

Advantages

  • Exceptional durability and longevity (100+ years)
  • Excellent slip resistance with flamed finish
  • Non-combustible (suitable for all BAL zones)
  • Low water absorption (0.2-0.4%)
  • High compressive strength (150-200 MPa)
  • UV resistant with minimal fading
  • Low maintenance requirements

Constraints

  • Higher initial cost than manufactured alternatives
  • Requires periodic sealing (12-24 months)
  • Heavy weight requires structural consideration
  • Limited thermal insulation properties
  • Can show efflorescence if not properly sealed
  • Natural variation between tiles
