Cemstone is a leading supplier of aggregates, including sand, gravel, base material and decorative materials such as clear limestone, river rock, granite, quartz and trap rock.

We deliver consistency and quality by providing the majority of our aggregate from our own close-by locations in Minnesota and Wisconsin. And we subject all products to testing at our own facilities, where we perform particle size analysis and petrographic examinations to ensure that our aggregates meet and exceed industry standards.

We use surface mining, quarrying and underwater dredge operations–working with the PCA, DNR and local communities to ensure that we are good neighbors. Learn more about habitat restoration and Cemstone’s commitment to environmental stewardship.

Cemstone recycles 100% of all leftover and torn out concrete that comes back to our facilities.  Throughout our strategically placed facilities, Cemstone has a number of recycling operations where we accept torn out/returned concrete and asphalt.

The Cemstone Companies work hard at finding & evaluating potential mining properties.  We are always looking for new properties to mine aggregates and are willing to work to achieve the best result for the property owner and their current tax status or family situation.  If you have a location you’d like us to consider, please contact us.
