US Silica Frac Sand Storage

US Silica operates several open-pit sand mines throughout the United States. In 2012, South Industries was contracted to build a storage facility to house all of the material mined from Silica’s “Voca Mine.” South Industries built a state-of-the-art, three dome facility, with the capacity to hold and automatically reclaim 40,000 tons of product. Each storage dome was built over a separate reclaim tunnel, equipped with a material conveyor for loadout. This configuration allows for the storage of three different products, each of which is held in a single component storage structure.
