Gypsum

Description

Some of the largest and most productive Gypsum Rock deposits are owned and operated by National Gypsum in the U.S. and Canada.

The company supplies its raw quarried gypsum to wallboard manufacturers, cement manufacturers and to agricultural users.  Gypsum is the primary core material in the manufacture of drywall, is used by cement manufacturers to regulate the set of Portland cement and by agriculture users for soil amendment and replenishment.

Our quarries, mines and processing plants are conveniently located to major markets. Gypsum is sold in bulk quantities by truck, rail and marine vessels.

Intermediary gypsum products such as gypsum stucco, land plaster and high strength gypsum retarder are offered at select National Gypsum plant locations.
