The granite's reputation for excellence has garnered recognition from architects and developers, who appreciate its superior qualities as an ideal construction material.

Our Quarries

Dakota Granite owns and operates five different granite quarries. Three Dakota Mahogany™ quarries: Sunset, Whetstone, and Superior Black. And two specialty quarries: American Bouquet and Bellingham. Each quarry produces blocks available for any project.

Experience Dakota Granite's hospitality!

We invite you to visit our quarries and headquarters in Grant County, South Dakota. The sales staff and quarry personnel work closely with block inspectors to ensure your needs are met, and block selections have been successful. The personal service, purchasing experience, and shipment of blocks will result in a smooth transaction of goods.

Blocks

Today's quarrying process utilizes wire saws and high-pressure drills. These quarrying techniques have increased quarry yields and minimized stress on the granite blocks themselves. Block inspectors may arrange a block yard visit with our Sales group to select from Dakota Granite's block inventory.

1. Flatbed truck

  • 46,000 lbs estimated capacity
  • single block truck loads - 200 F3 (5.6 m3) maximum
  • two or more block truck loads - 183 F3 maximum

2. Container

  • 43,500 lbs estimated capacity, 200 F3 (5.6 m3) maximum
  • Containers are stuffed at the quarry and transported via truck to the container yard in St. Paul, Minnesota. Blocks are then loaded aboard a train for shipment to the coast to be shipped via vessel.
  • Estimated transport time of 6-8 weeks
  • Container Stuffing Fee Applicable

3. Railcar

  • 200,000 lbs estimated capacity, 850-875 f3 (24 m3) maximum
  • Gondolas are railed to eastern rail sites or Norfolk Port. At the port, blocks are placed into containers and loaded onto an ocean vessel. Shipment times vary depending on the booking schedule.
  • Ocean-going containers can be loaded up to 60,000 lbs when transported to port by railcar.

The estimated weight of granite blocks can vary because of shape and agreed-upon measurements.

TO ESTIMATE WEIGHT, CALCULATE:

  • When sawn to size with packaging for transport: f3 = 190 lbs or m3 = 3.36 tons
  • Rough block size: f3= 220lbs or m3 = 3.88 tons

Architectural

Dakota Granite has a long history of working closely with architects, design teams, and specifiers to solve their granite requirements.

Granite is an all-natural product having many uses and applications in the building and construction industries. Granite is the most durable of the natural stone products and one of the most sustainable materials used in the construction field. Because of the numerous quarries around the country, granite often qualifies for LEED points due to the 500-mile or less radius from the quarry to the project.

Virtually 100% wasted or damaged granite pieces can be recycled to be used in other areas of construction or landscaping. Dakota Granite produces products such as thin veneer, full bed ashlar, and various signage products that are manufactured from "scrap" pieces from our monumental division. Granite is abundant in nature, recyclable, low to no maintenance, durable, affordable over the building life cycle, and adds value to your project.
