Overview
Executive summary

Premium quality limestone wall cladding in standard 600x300x20mm format with tumbled edges providing a softened, aged appearance. This sedimentary stone offers excellent durability, thermal mass properties, and complies with AS 4456 series standards for masonry units. The tumbled finish enhances slip resistance and provides a traditional aesthetic while maintaining structural integrity. Suitable for both adhesive fixing (AS 3958.3) and mechanical fixing systems.
