Always Listening, Testing and Improving

We listen to our customers to determine where we mine, what we mine, how we process the materials, what products we develop ⁠— and even how we deliver them. An entire U.S. Silica team dedicated to quality works with our R&D teams and our plants to constantly test our incoming sand, ores and finished products. That's how we ensure that the products we ship to thousands of customers globally are always world-class quality.
