Our surface mines at the Berkeley Springs facility use hard rock mining methods to produce high-purity sandstone. The plant uses propane, fuel oil and electricity to make whole grain, ground, and fine ground silica. Berkeley Springs also produces a synthetic magnesium-silica product called Florisil.

Since acquiring the facility, we have renovated and upgraded its production capabilities to enable it to produce multiple products through various processing methods, including primary, secondary and tertiary crushing, grinding, flotation, dewatering, fluid bed drying, mechanical screening and rotary drying processing. Berkeley Springs meets a wide variety of focused specifications from customers producing specialty epoxies, resins and polymers, geothermal energy equipment and fiberglass serving end markets such as glass, building products, foundry, chemicals and fillers and extenders. 

Mining at this location has been a part of the local landscape for over a century. The Pennsylvania Glass Sand Company, from Lewistown, PA, came into the area in the late 1800s and acquired much of the land and began what was then known as Berkeley Works. We acquired the Berkeley Springs facility in 1987 by merging with the Pennsylvania Glass Sand Corporation.


U.S. Silica has been a thriving part of the community, employing multiple generations of families from Berkeley Springs and the surrounding area. Many of the Berkeley Springs employees strive to be good neighbors and dedicate their free time to local fire and rescue organizations, youth leadership positions such as coaching and scouts, and to community needs like food drives. The plant also participates in an annual "adoption" of a disadvantaged family at Christmas and donates sand products for local recreational use. The Berkeley Springs facility has been recognized with a Mountaineer Guardian Award for the effectiveness of the company's safety program.
