US Aggregates’ Flat Rock Quarry serves the Shelby County region. One of their key products is AWP-300, an all-weather patch that remains extremely workable even in low temperatures that would render similar high-priced materials inoperative. The location provides donations and volunteer support for the Flat Rock Fire Department, Marietta Volunteer Fire, Edinburgh EMS, Nineveh Volunteer Fire, Southwestern, Flat Rock School Corps, Invent Learning Hub, and various local youth sports.
