Concrete Materials - Founded in 1930, Concrete Materials produced crushed rock from a small processing plant in west Sioux Falls. The company later added a small sand production plant near Rowene and, after World War II, opened Sioux Falls' first ready mixed concrete plant adjacent to the original rock quarry. Sweetman Construction Co. purchased Concrete Materials in 1952. Since its inception in the 1950s, the company has continued growing and expanding. Concrete Materials owns and operates aggregate and concrete production facilities in Chancellor, Yankton and Sioux Falls, and its service area encompasses eastern South Dakota and neighboring states.

Arrow Magnolia - This NRMCA Associate member was founded by the Hanley family in 1927 as Magnolia Chemical. Arrow Chemical, started by Morris Shwiff in 1963, was led by the Shwiff and Kenner families from the late 1960’s up through 2004. Arrow and Magnolia merged in 1985, forming Arrow-Magnolia International (AMI). ChemCo Chemical (ran by Charles Davidoff and family) was acquired in 1990 and run as a separate division until 2005. This merger created the opportunity to become a NASDAQ-traded company in 1992. In 2005, the Tippeconnic family bought AMI and took it private, creating Arrow-Magnolia International Inc. Read more.
