About Us

MDI Rock specializes in natural stone products designed to enhance and harmonize with the natural beauty of the American Southwest. We’ve been providing quality landscape rock products in Arizona and beyond since 1988.


We carry over 50 colors of decorative groundcover, plus riprapflagstonetopsoilsandgravel, and a huge selection of boulders. Our accent boulders range from basketball size all the way up to compact car size and larger.

We deliver from our Phoenix, Queen Creek, or Prescott locations to all points. Whether you’re across the street or around the globe, we will gladly accommodate you. Not only do we deliver, but our state-of-the-art placement crane will also help you get the right boulder just where you want it for a reasonable price.
