Cantera Stone Advantages

Life cycle—While thin veneer stone is a strong product, it does not have the life cycle of Cantera Stone.

Moisture control—Cantera Stone, with cavity wall construction and IWR, is a significant selling advantage if moisture control is a concern.

Accent capability—Installing brick and custom cast stone accents on top of cultured stone is not possible because there is no bearing point.

Ready order—Cantera Stone uses Reading Rock’s Ready Service program and is available in three weeks or less.

Cost efficiencies—Labor and materials are less than natural stone precuts.

Durability—Other machine produced natural stone products cannot be used at grade or cleansed with acid-based products.

Standards—Cantera Stone is consistently produced to an ASTM standard, ensuring product performance.
