About Us

In April 2004 Tri-State Materials identified the need for a more efficient and cost effective way to deliver landscape products the end user. With a combined total of over 50 years of experience in the landscape supply and trucking industry we were able to streamline the delivery process throughout the western United States. We work hand in hand with our network of landscape architects, contractors and the end user to keep your job on budget. For the residential homeowner, we offer a wide variety of surface boulders and quarried boulders as well as rip rap and decorative gravel for landscaping. For areas you wish paved, check out our lineup of flagstone. We also have available top soil, mulch materials, and more. We look forward to meeting you at one of our locations, in Winchester or Coachella. Come on down and browse around, or check in at the office for some expert assistance in finding just what you need.
