Sterling Pit
A closer look at our Sterling pit in action!
Our new wash plant is officially up and running, bringing a whole new range of high-quality materials.
We are currently adding washed products for all your project needs.
We are excited to service our customers with septic sand, C-33 concrete sand, and more!
This mining site supports our Material Sales operations, producing aggregate, gravel, and sand. Powered by a state-of-the-art electric plant and a new wash plant built last year, this facility delivers clean, high-quality material efficiently.
