NSSGA at the Celebration of Construction on the National Mall


The National Stone, Sand & Gravel Association (NSSGA) represents the producers of aggregates (stone, sand, gravel and industrial sand), along with the equipment manufacturer and service providers that support them. We advance public policies that protect and expand the safe, environmentally responsible use of aggregates that build America’s infrastructure and economy. Our 400 member companies produce more than 90 percent of the crushed stone and 70 percent of the sand and gravel consumed annually in the United States. NSSGA members are responsible for the essential raw materials found in every home, building, road, bridge and public works project in the United States.


NSSGA’s vision is a favorable public policy environment that fosters business growth for the aggregates and construction materials industries. We are committed to rebuilding the nation’s aging infrastructure to ensure America’s economic prosperity and global competitiveness in the 21st century and beyond.

Our Members


Our industry operates over 9,000 locations in the U.S. and employs over 100,000 people in high-paying jobs to source 2.5 billion tons of stone, sand and gravel each year that are used to sustain our modern way of life and build our nation’s communities and infrastructure. These materials are the building blocks of our American infrastructure and play a crucial role in everything we touch: some may be obvious - roads, railways, bridges, tunnels, water supply, sewers, electrical grids and telecommunications; and some may surprise you - televisions, phones, and other consumer electronics. Many of these projects are funded through the recent passage of the Infrastructure Investment & Jobs Act. Our industry drives American growth and opportunity by producing sales in other industries; building new infrastructure; and creating jobs.



NSSGA members are proactive members of their communities who operate sustainable businesses, both during production and at the end of a quarry’s life cycle. Our members value innovation and are effective stewards of the land, water and air. They also add community benefits once extraction is completed and work with their local communities on reclamation efforts which can take many different forms, such as farmland, parks, wildlife habitat areas, water reservoirs, community developments, recreation spots, nature preserves, alternative energy generation and more.
