A Family Business Since 1935

The story of Mulzer Crushed Stone is very much the story of success. It started in 1935 when Roland, Edgar and Arnold Mulzer, Sr. began building culverts for highway construction. In 1946, the Mulzer brothers saw the need for a close supply of construction aggregates during the post World War II construction boom. To help fulfill that need, the Mulzers opened their first limestone quarry at Eckerty, Indiana, and delivered on their first contract…1,500 tons. The Mulzer family has been delivering quality aggregrate products ever since.
