I do not have access to the latest information on the Aflenz Limestone. However, in general, the suitability of a limestone for heavy use areas depends on several factors such as its durability, hardness, porosity, and density. Generally, denser and harder limestones are better suited for heavy use areas as they can withstand heavy traffic, weathering, and abrasion. It is important to consult with a qualified professional who has experience in working with natural stones and can provide guidance on the suitability of a specific limestone for a given application.
