Red Rock Granite, Inc. in Mosinee, WI is a granite quarry operation that has been family owned and operated since 2001. Prior to owning Red Rock Granite Inc., we owned and operated Koss Trucking & Granite, which was a single-quarry operation with a small fleet of trucks. Business grew rapidly, and in 2001, we purchased Roehl Granite LLC. This provided us with much of the needed resources including several color variations of hard rock through 5 quarries and over 500 acres to mine.

We specialize in crushing and mining road materials and decorative stone all ready and on hand. With several sizes of breaker run, road base, and decomposed rotten granite, we have all you need to get the job done right.

With a large supply of quality products to last over 5 generations combined with family values and customer courtesy, Red Rock Granite, Inc. constantly strives to be your provider for many years to come.
