A decorative or utilitarian streetscape is created by first applying a twopart epoxy, then covering it with one of Kafka Granite''s many crushed aggregate options. Kafka Granite does not install streetscapes—instead, we offer a wide selection of aggregate for those who install these projects or anyone looking for material to do so.
High friction surfacing (HFS), bonded to a road surface at high risk locations, has been shown to significantly reduce road fatalities and serious injuries,, HFS saves lives. Calcined bauxite is the preferred aggregate for use in HFS systems due to its unique ability to resist polishing and abrasion by vehicle tires. Calcined bauxite is expensive, negatively impacts the environment due to ...
