50 Colors of Crushed Stone and Recycled Materials

Specialty Aggregates produced by Kafka Granite are used in a wide variety of manufacturing, construction, and architectural design applications. As the producer of this specialty crushed stone, we are able to monitor quality starting at the source. Whether it’s blasting at the quarry, crushing to a specific grade, drying a material, or simply the storage of the finished product, every effort is made to ensure a clean and consistent specialty aggregate is delivered to our customers.

Kafka Granite sources granite, marble, and quartzite from dozens of quarries throughout the United States and Canada. This enables us to offer a wide variety of natural stone. When you combine a large assortment of natural colors with our fine tuned custom crushing abilities, we’re able to manufacture a specialty aggregate that meets or exceeds your specifications.

Stone is a natural material and slight color variations may occur. Product is photographed wet to better show color. We encourage you to request complimentary samples before ordering. Granite, marble, and quartz are general classifications. If specific chemical make-up is important, please speak with a sales representative about aggregate testing.
