History
Dayton Sure-Grip & Shore was founded in 1924 by Art & Carl Kinnenger with help from Charles Danis and Fred Kramer. Carl Kinnenger held the patent on the snap tie design (to hold formwork together) and Dayton Sure-Grip & Shore was licensed to sell it in the U.S. out of their Downtown Dayton location.

In 1953, Danis Hunt Construction acquired Dayton Sure-Grip. After beginning bar support production in 1959, Sure-Grip, Inc is founded in 1960, and the company relocated to Miamisburg, Ohio. In 1975, Dayton Sure-Grip purchased C&M Chemical Co. out of Sycamore, Illinois, beginning their production of chemicals. After the purchase of Superior Concrete Accessories in 1982, the company changed their name to Dayton Superior Corporation.

A series of acquisitions followed, leading to international expansion (purchased Superior Concrete Accessories of Toronto and Cogan Wire Company of Montreal), and the purchase of Symons Corporation. Symons specialized in form systems, and manufactured shoring, formliners, and chemicals, drastically expanding Dayton Superior's number of products offered.

In 2006, Dayton Superior went public (NASDAQ: DSUP). Three years later, the company again went private, led by Oaktree Capital Management. The company then relocated to its current headquarters in Miamisburg, Ohio in 2010
