A History of Responsible Excellence

Stewart Mining Industries, Inc., has been a part of Florida’s construction material industry since 1978, when its first location was opened in Fort Pierce. What began as a small sand and fill operation has grown into a diverse company providing construction aggregate materials for concrete products, roadways, golf courses, and beach restoration.

Stewart's first sand mine was donated to the City of Fort Pierce
as a water retention facility. 
Stewart currently operates three mines and is in the process of
establishing additional operations in key areas to help meet the needs of a rapidly growing state. The President and Founder of SMI, Nick Stewart, is a fifth generation Floridian and is committed to keeping Florida beautiful through responsible mining practices and land reclamation.
