Superior Northern Granite Blocks

In our privately run quarries, we can tailor to our customer’s needs and utilize our existing inventory or quarry blocks to specific sizes. We can produce large oversized blocks, or blocks that are smaller manageable sizes that can be optimally handled by your specific equipment. We have a great selection of both Superior Northern Granite and Limestone blocks to choose from.

We regularly cut a wide variety of slab thicknesses for our clients. We can produce slab sizes to best accommodate small or large part needs. Slabs can be finished to your specifications.
