OUR HISTORY

A Legacy of Innovation

How long does it take to prove a company’s innovation leadership? Seems like 70+ years is a good start. For the confidence that comes from decades of innovations, CROM is the clear choice.

Our Company is built on the ingenuity of J.M. Crom Sr., and his sons, Ted and Jack, who are credited as pioneers of prestressed concrete tank technology in the 1930s. Building on his innovation, the CROM Corp. was officially born in the early 1950s. We‘ve been a leader in building and restoring the nation’s essential infrastructure ever since.
