An excellent choice for patios and walkways, this bluestone is sawed to 1″ or 1.5″ thickness grades. Consistent stone thickness allows for easier installation on the job site. The stone paving surface is “heat treated” which gives a consistent uniform texture. Select Blue Thermal Finish Pattern is hand sorted for clean, blue and gray color tones creating a very uniform and refined look. Standard pattern sizes range from 11.5″x11.5″ to 23.5″x35.5″ adjusting in 6″ increments.
