The National Lime and Stone Company

Who We Are

Founded in 1903, the National Lime and Stone Company is today one of the major producers of crushed stone in the United States. Three recurring themes have been basic to the way National manages its business:

 •Add meaningful and sustained value to customer operations

 •Seek continued improvement in operational efficiency and effectiveness

 •Pursue controlled, profitable growth

National, through its people, works diligently to develop and sustain its reputation as one of the nation's most dependable sources of high-quality construction aggregates and industrial minerals.

National manufactures a wide variety of products for the nation's infrastructure and a number of basic industries. Crushed stone - in one form or another - is found in most construction projects. Additionally, National produces significant quantities of specialty dolomite-based minerals for the glass and steel industries.

Other major uses of National's products include agricultural and lawn care applications: environmental remediation; and acid neutralization and pollution control. They are also key ingredients in industrial fillers and sound-deadening products used by the automotive and roofing industries.

National is a long-time steward of its non-renewable natural resources. It has well-defined programs to preserve the land and the environment during all stages of commercial production and thereafter.

Driven by a century-old tradition of customer service, National operates highly-automated and efficient production facilities and is unrelenting in its continued efforts to reduce costs and offer superlative customer service.
